It allows to completely trim the connector while following the shape of the crown. There are three options: <CUTHOLDERS> <CUTHOLDERS1> is the same as <CUTHOLDERS> and it has the same behavior <CUTHOLDERS2> is used with the "red" links and can be used to make a partial trim in contact with the tooth. <CUTHOLDERS> There can be both of these options in the same strategy: <CUTHOLDERS...>: <CUTHOLDERS1> with a Z limit (for example between -2 and 2) ; <CUTHOLDERS2> with a Z limit 0 and 2. In this case the red link will be reduced near to the tooth surface, without being cut. Sample: TRIM CONNECTOR<CUTHOLDERS> <LOCK> For use with: Any Machining The Machining Parameters and the selection of the Curves / Surfaces cannot be automatically modified by the software during the template implementation step. In this case, you can lock certain variables on a machining operation like: • Tool Axis Orientation • Delimitation / Boundary Curve Value • Surface Selection • Machining Parameters These items will not change during the template implementation step. <NOSEL> (Obsolete) For use with: Any Machining This function indicates that the selection of surface cannot be automatically modified in the machining process <NOROT> For use with: Any Machining This function indicates that the machining is done in 3-axis without using optimization angle during the import phase, regardless of the possible remainder of material in undercut areas. <UNDERCUT> or <UC> For use with: Zig-Zag, Z-level Profiling, Profile 3D Pocketing With 3D Profile Pocketing <UC> works in continuous 5-axis and there are 4 parameters (always optional). For Example: <UNDERCUT20/20/0,5> Max Undercut 20°/ Start Angle on Border 20°/ Final Angle (In the internal cavity) 0 degree, Angular Step on the XY 5 degree. Aside from these parameters it is also possible to perform 5 axis continuous machining with different increments adding the <SPIRAL> parameter. For instance, it is possible to work with the codes: <UNDERCUT15/10/10><SPIRAL0/5/0.05><SPIRAL5/0/0.15> to machine the first 5 mm with step 0.05 and the rest of the cavity with step 0.15 <UNDERCUT> or <UC> With Zig-Zag machining for both sides, it is possible to indicate where the material was milled from the opposite machining. To activate this option, the MZ (Mirror Z) parameter is required. Example: <UNDERCUT0.2,MZ>. The value is optional and it allows to manage different Z value increment. These values reduce the stress on the tool. In case of 5 axis simultaneous cavity machining, the behavior can be optimized when the starting angle has not been defined. The actual behavior suggests its use only by setting the maximum inclination angle, without the indication of the starting angle (e.g.: <UNDERCUT10> instead of <UNDERCUT10,10>). The execution time will be reduced, maintaining the same machining quality. Sample: INTERNAL FINISHING<UNDERCUT10/3/3> <DMIN> .. <DMAX> For use with: Drilling This function indicates the minimum/maximum diameter for machining holes. With these variables, you can ensure that a particular operation will only be applied to holes that meet this setting’s minimum or maximum diameter. This allows the user to place logic into the strategy so that smaller tools (like 1mm) aren’t trying to drill out larger holes (like a 4mm diameter access hole) that can be easily accomplished with larger tools (like a 2 / 3mm tool). <BREAK> For use with: Drilling If an item is present that has a blind hole, you can use the command <BREAK> on drilling operations to punch through. In machining name add the "BREAK" word and the software will calculate the drilling processes also without cylinders. <SPIRAL> Strategy for "3d curves pocketing", for a 3-axis continuous spiral machining. Either a "standard“ or a "lollipop“ tool with a thinner stick, can be used to eliminate the "undercut“ . This strategy also includes the possibility to set the distance from the border where to start and end the machining. For instance, it is possible to input: <SPIRAL0/5> or <SPIRAL2/10> or <SPIRAL5> or <SPIRAL-5>. Moreover, it is possible to create a machining with different zones and different increments. For instance, it is possible to input, inside the machining's name, the words: "<SPIRAL0/5/0.05><SPIRAL5/0/0.15>" to set which kind of machining to execute: with 0.05 mm increment for the first 5 millimeters of the cavity, starting from the "prepline", and with 0.15mm increment for the rest of the cavity. <SPIRAL> The parameters of the "<SPIRAL...>" strategy are 3: start, end and increment. The start and the end can be negative, in this case the machining will begin from the back and not from the border. The third parameter (increment) is not mandatory, in case it is not specified the applied increment will be the value shown in the table of machining parameters. The increment value shown in the table of machining parameters must be always specified. Sample: INTERNAL FINISHING<SPIRAL0/2/0.05><SPIRAL2/0/0.1> <SLOPE> For use with: Z level Profiling This function allows you to indicate two angles: one for the stock and one for the model. The machining will "draft" and the lateral side of tools will not be in contact with stock/model. Example: <SLOPE5> indicates a descent angle of 5° to stock. <SLOPE2/20> or <SLOPE25/3> indicate two different angles. Sample : INTERNAL ROUGH<SLOPE2> <DVAR> For use with: Drilling This function is used to increase or decrease the diameter of a hole during the drilling operation. This would be for any hole that the drilling operation is applied to. Syntax: <DVAR2> or <DVAR-2> DVAR2 adds 2mm onto the diameter of the drilling operation DVAR-2 reduces the diameter to be drilled by 2mm. Without <DVAR2> <DVAR-0.5> <OSO> Strategy that is used to mill the element until the end of the disk in only one side. This machining is used to generate a quick trial implant to test on the patient. To use this strategy add in the name the option <ONESIDEONLY> or <OSO>. Currently the supported machining types are: pocketing and ZLevel contouring. With this option the machining will be done until the end of the disk instead of the max external point. Sample: RESTMATEXTFINISM&S5A<OSO><LTH><TS5,6><T:/D1B/REFMS5-ST-?> <MILLCONE> Strategy that allows to mill, with flat tip tools, the conical parts of the screws by means of a drilling machining. When drilling with a spiral milling, the conical parts need specific tools with the tip shaped to fit the support part of the screw's head. Alternatively, these parts can be milled by means of "XY contouring" machining, using flat tip tools . So it is possible to execute a drilling with a spiral mill using flat tip tools, obtaining a radial re-machining of the conical parts. To enable this operation, please write <MILLCONE> in the name of the machining or <MILLCONE,20> if, for example, you want to set 20 as the number of "radial" cuts to be performed. Sample: PRE-HOLE SIDE 0<DMIN2.11><ZI1><MILLCONE,40><TS3,4,12> <PORTIONn/m> For Use With: POCKETING PORTION allows you split the roughing into 2 or 3 phases in the Z axis and spread this across multiple operations, therefore allowing you to sequence other operations in the middle. Tool breakage / overheating can occur during the roughing of the first side, when the tool tends to plunge down rapidly into cavities which may have low clearance (ie: The space between two connectors). In this case the material that has not yet been removed from the other side could impede the cutting, which may cause excess heat and stress resulting in failure of the tool – This can especially be the case with high speed machines. In the example below, we have split the roughing of the same side into 2 phases and arranged the roughing step from the other side in between the two phases. This allows us to rough out a hole from the other side of the disk to create extra clearance for cutting on the original side & avoiding a potentially damaging accumulation of the material during the first roughing steps. <PORTIONn/m> SYNTAX: To set the "phase“, it is necessary to input the code <PORTIONn/m> in the name of the machining N: Sets the current number of the phase and M: Sets the number of total phases. For instance: <PORTION1/2> or <PORTION2/2> We can also split the same portion across multiple operations as well. To do this , the code “DEEP” or “DEPTH” has been added that allows you to set the depth of the machining to perform or start from. For instance, <PORTION1/2,DEPTH1.5> will machine only the first 1.5 millimeters depth of the portion 1: <PORTIONn/m> CONTINUED: <PORTION1/2,DEPTH-1.5> will machine the rest of the portion 1 starting from the first 1.5 millimeters, and working downward. NOTE: The code DEEP (or DEPTH) can also be performed alone (without <PORTION...>). E.g.: <DEEP2.3> <PORTIONn/m> Example of machining sequence: - roughing of the cavities side with <PORTION1/2> - roughing of the opposite side, without codes "<PORTION...>" - roughing of the part still to be machined of the cavities’ side, with <PORTION2/2> - other machinings Otherwise: - roughing of the first portion of the cavities side with <PORTION1/2> - eventual elimination of the stock interference with the axes of the cavity, to free the access to the cavities with strong inclination - roughing of the cavities - finishing of the borders - finishing of the cavities - roughing of the opposite side, without codes "<PORTION...>" - roughing of the part still to be machined of the cavities’ side, with <PORTION2/2> - finishing of both sides <MATRES> For Use With: POCKETING This feature will prompt the creation of a dynamic “RAW” with a specified tolerance in the background of the software that the CAM can check toolpaths against during calculations. This should only ever be applied during the FIRST roughing step, otherwise, the progress from earlier operations will be lost as the Dynamic RAW will be reset. MATRES accomplishes the following: 1) Resets the Dynamic RAW 2) Assigns the value set as the tolerance for updates of the dynamic RAW that occurs after each subsequent calculation (when the parameter “Update Worked Model” is selected under General Parameters. For instance <MATRES0.04> means that before performing the machining, the “Dynamic Waw" will be reset and the tolerance of 0.04mm will be applied to the next operation of update of the machined model. <MATRES> This new option brings two main advantages: a) to manage different tolerances in different situations, with the purpose to apply always the best possible choice between processing time and precision of results. This allows to set a higher tolerance value to manage the "dynamic raw" only during roughing, or to set a lower tolerance value to manage the "dynamic raw" in finishing strategies (identification of the rest material in finishing). b) to reset the "dynamic raw" in the different phases of the machining. For instance: to perform a general roughing using tools with different diameter, which identify the rest material to be removed on the basis of the condition of the model. Then to "reset" the machined model to perform the roughing with different tools inside the cavity, eventually reducing the tolerance of the "dynamic raw" and working with a model that is lighter than the one obtained at the end of the general roughing. <LTH> For use with: Pocketing, Z Level Profiling This feature forces the operation to stop calculation when it reaches the lowest connector. This will save time and prevent the operation from cutting material that will be passed over from the other side of the stock. Syntax: <LTH> or <LIMIT-TO-HOLDERS> Without <LTH> With <LTH> <TYPESEL> / <TS> For use with: Any Machining <TYPESEL> or <TS> Allow us to tell a specific operation to only apply to an imported item that is categorized accordingly. When the strategy is imported, any milling operations that do not apply to a particular TS of the items that you’ve imported for machining will not be imported into the job. This allows for us to store the cutting parameters for many different restoration types within the same strategy – simply by separating them using TYPESEL Codes. The values which can be associated to the <TYPESEL...> command are: 1 Single Coping 2 Coping/Framework Bridge 3 Abutment 4 Implant Bridge 5 Model 6 Single Die 7 Glue Object/Hybrid Abutment 8 Inlay-Onlay-Veneer 9 Anatomic Crown 10 Anatomic Bridge 11 Bite Splint 12 Anatomic Bridge Implant 13 Framework 14 Telescopic Crown (Only from 3Shape / Exocad) 15 Bar 16 Scan Abutment NOTE: You can also choose to explicitly exclude specified TS items from a milling operation by preceding the TYPESEL number with a “-” SYNTAX: <TS1,2> Operation only applies to items specified as 1 and 2 (Copings and Framework Bridges) <TS-1,-2> Operation applies to any TYPESEL item except for 1 and 2. <DMIN0> For use with: Drilling When drilling from the top of a screw access hole on abutments, this feature can be used to prevent the tool from going too deep in a hole and trying to machine out a hole with a lower diameter. This is particular behavior that can be observed when working with flat screw rest seats on Titanium Abutments as shown below. Syntax: <DMIN0> With Without <IOF> For use with: Pocketing, Z-Level Profiling, Profile 3D Pocketing, Zig-Zag The <IOF> code can be used to activate an "internal" delimitation curve offset. This offset is different from the one that is set in the offset parameter for the selected delimitation boundary curve. This parameter can be extremely useful for example when we want to machine between two areas but we want to preserve stock around the inner curve (like the area between the part border and a margin – Image below) Syntax: BRIDGE FINISHING<IOF-0.3> <MSVY / MVSN> For use with: Pocketing, Z-Level Profiling (Model Milling) MILLVERTICALSIDEYES> or <MVSY> and <MILLVERTICALSIDENO> or <MVSN> These codes have been introduced for the optimization of the models’ machining. They are used in case you want to calculate, with <MVSY>, the tool-path of vertical areas (in Z) or in case you want to exclude these zones from the machining with <MVSN>. Usually the machining is calculated both from upside and from downside, to reach the "middle Z level" of the item. Some geometrical items, like bars or implants, could present large vertical areas. SUM3D Dental includes these areas in the machining "side 180" (the one which is generally performed first). In some strategies it could be necessary to invert this behavior so, to this end, we added the possibility to set these codes. <BFH> For use with: Pocketing, Z-Level Profiling This code starts the machining from the deepest connector. This code could be useful, for example, to perform the roughing on one side with the code <LTH> and then a “ZLevel Profiling" (which is faster) starting from the end of the last roughing step, setting <BFH>. <DINC> It was noticed that during the roughing, when the tool dips in blind-end narrow cavities, it overheats and/or breaks because it cannot output the rest material. For this reason, an option was introduced to apply a "peck drilling cycle" by setting <DINC...> (Depth Increment for Narrow Cavities ). "<DINC…>" // Depth Increment for Narrow Cavities allows to set a "peck drilling cycle" when the tool descends in narrow and deep cavities. The set value represents the "Z" step increment to be applied for the "peck drilling cycle". When the tool descends in very narrow cavities, every "xxx" millimeters (value set by <DINC...>) of milled depth, the tool rises outside the cavity and then descends again to the previous milled Z level, to reach the lower preset raising point. By means of this raising the tool can cool down and output devices (water, air or suction) can clear the chip. Also in case the "<DINC...>" parameter is not set, a "default" value of one/third of the tool’s diameter will be applied. Sample: CROWN ROUGH<DINC0.2> <MINC> To complete the options given from the <DINC...> code during the "pocketing" operations, it is now possible to set the code <MINC...> to specify a minimum "diameter" of the cavities to mill. For instance, writing "<MINC5>" in the "pocketing" name, the cavities with a diameter lower than 5mm will not be milled. We introduced this option to avoid to descend into cavities which are just a little bit larger than the tool. It will be possible to mill those cavities later on with a lower diameter’s tool, which uses the "dynamic rough " to detect the areas where the previous tool has left the material. <MAO> or <MILLATTACHMENTONLY> This code allows to set to machine only the engagement meshes (<MAO>) or to machine all meshes except those of engagements (<MAO0>). The split up of engagement meshes, is only possible (at the moment) importing an Exocad nesting file, but could be developed for other “structured” files (containing more information than STL), according to the demands recognized by the customers. <T:/> A new “keyword”, recognizable by the machine name has been added to be able to recall a tool from the tools archive: <T:.....>. After the sign ':' and before '>' there is the "name" (description) of the tool that you want to "call" from the tools archive. A tool with the "name" requested from those assigned to the selected machine tool, or from those that do not have it. Since every tool can have different cutting parameter for several material, from the archive, the tools associated to the related material have been extracted. This code has been added in order to simplify the strategy changes, intervening on the tools archive instead of the strategy files, to change the tool length or the cutting parameters of the recalled tools. If the called tools are not in the archive, a table with the with the list of missing tools is shown and the machining is not started. <T:/> Using codes TOOLSTABLE and REPOTOOLS, now is possible to use the same tool number with name partially different. Comparing the tool names (description) the text after "/" is ignored (including the "/" char). It means that two tools with description "D1/A" and "D1/B", with the use of TOOLSTABLE and REPOTOOLS, are considered as the same tool. This possibility has been added in order to recall the same tool with different parameters using the "<T:....>" code. The use of several copies of the same tool of the tool archive, is needed when you want to use it for different machining, applying different machining parameters. Sample: FINISHING EDGE<FF><TS3,4,12,15><T:/D06F/FE-SP-?> <EZS> This code (Extend Z Start) allows to start the roughing machining a bit higher. The value set is used to extend the Z of roughing machining start. It could be useful if you suspect the use of irregular raw part. Sample: INTERNAL ROUGH<SLOPE2><EZS0.3> <ZI> In case of deep holes milling, the tool overheating could happen. To help its cooling, the code <ZI…> has been added in the holes milling. If this parameter is set, an up movement to the hole starting level is applied at every achievement depth corresponding to the set value. For example, <ZI3> indicates that every 3 millimeters of depth, an up movement was applied before continuing with the machining. Sample: PRE-HOLE SIDE 180<TS3,4,12><ZI1><FF><T:/D1F/PH180-SP-?> <4A/5A> In order to use the same “strategy” both on 5 and 4 axis machines, we have added the possibility to set in the name of the machining the abbreviations: “<4A>” for the machining that must be used only on 4 axis machines. “<5A>” for the machining that must be used only on 5 axis machines. For example, if a specific operation (e.g.: finishing of internal cavity of a crown) has to be executed in a different way on 4 axis and 5 axis machines, it is possible to set both operations in the same “strategy”, setting the abbreviation “<4A>” in the name of the machining that has to be used on 4 axis machines, and “<A5>” in the name of the machining that has to be used on 5 axis machines. Sample: INT FIN 5 AXIS CONT<FF><UNDERCUT10><5A><TS1,2,9,10,14><T:/D1B/IF5-?> <MT> In the name of machining, the <MT:...> code has been added, in order to point out that the machining is applicable (or not) to the listed materials. The name of material must be written using the following acronym: Zirconium: zr Zirconium translucent: zrt Pmma: pmma Composite Pmma: pmmac Wax: wax Polyurethane: pu Gypsum: gyps Titanium: ti Titanium grade 2: ti2 Titanium grade 5: ti5 Chrome cobalt: crco Aluminum: al Glass ceramic: gc Ultimate: ult <MT> It is possible to set several materials, separated by a comma. To specify that the machining is not applicable to a material, you have to set the letter '-' before the name of material. Examples: <MT:zr,zrt> <MT:pmma> <MT:-pmma> <MT:-ti,-ti2,-crco,-al> Sample: INTERNAL ROUGH<#STANDARD//1><RR><SLOPE2><MT:-PMMA><T:/D2B/IRST-?> <LMIN...> ...<LMAX...> They are used to set the value of length (minimum and/or maximum) that curves in the machining must have. Accordingly, the curves with a development (length) less than the value set by <LMIN…> or greater than the value set in <LMAX…> are excluded from machining. It is possible (but not necessary) to set both codes in the machining name. <FA…> In the “Z level profiling” roughing machining, the managing of <FA…> code (Fence Angle) has been added. You have to use it together the activation of “Constant oversize toolpath”. The various “Constant oversize toolpath” types have in common the application to the object areas with a “low slant”. Usually the separation between the area where the toolpath “Constant oversize toolpath” is applied and the remaining part of machining is located where the angulation of the object is about 45°. Using <FA…> code it is possible to set the angle to be used to determine the separation threshold of the area of “Constant oversize toolpath”. <GRIND...> This funtion allows for roughing and in some cases the finishing of Glass Ceramics or Lithium Disilicate blocks. This is only used with Zig-Zag or “one way” milling operations. GRIND4 & GRIND5 are the newly managed codes and are more efficient for dental application using a stock blank. <GRIND...> This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> It is necessary to set the code "<GRIND...>" followed by some optional parameters. The first parameter can be 1 (default) or 2 (<GRIND1> or <GRIND2>) and sets respectively if it is a roughing of half of the block or a rest material removal on the lower half of the block, left from the previous roughing. We usually suggest to rough the block on both sides with <GRIND1> or <GRIND> (it's the same) and then to perform two more machining with <GRIND2> on both sides to remove the rest material left from the previous roughing on the lower half of the block. With the “3D curves pocketing” 5 axis machining of cavities, it is possible to use the parameter “increment between Z repetitions”. In this way it is possible to manage the maximum working height of tool. The other parameters of the <GRIND...> code are: a) machining tilt angle b) minimum angle of pitching. This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> Both values are optional. For instance: <GRIND1/30/5> sets a tool (or an item) angle of 30 degrees and applies a minimum pitching angle of 5 degrees. The first value allows (with an high value) to partially or fully reach the "anatomic" parts of the "occlusal side" of the tooth. The second value avoids the tool’s milling with its lower central part, which cannot remove material. It is also possible to perform 3 axis millings, by setting <GRIND1/0> or <GRIND1/0/10> (10 degrees of pitching angle), the only disadvantage will be that the anatomic parts of the occlusal side of the tooth will not be milled. It is considered the use of ball tools, but it is possible to use bull tools too, at the moment only with 3 axis machining. The use of bull or different tools, with 4 or 5 axis will be managed on demand. During the <GRIND2> machining the following parameters (the angles) won’t be considered as it is a 3 axis machining. As previously said, it is possible to select a "zigzag" or " one way" milling. This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> In case of a 3 axis machining (<GRIND1/0>), there’s no difference between the two machining. In case you are working with a tilt angle, the choose between ZIG-ZAG or ONE WAY milling can be determined by the speed of the machine’s rotating axis. The suggested parameters managed for these machining are: a) passes’ direction angle (which must be perpendicular to the block’s assembly axis). b) increment between passes. c) Z step increment, sets the maximum height the tool can remove. d) passes’ extension value, sets a safety value to compensate eventual position’s defects when clamping the block. For instance it can be suggested a value from 0.5 to 1 mm. The "raw" (block) sizing must not be increased during its creation, to grant “safe” values, as this value is aimed at this use. This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> The managed parameters between those selectable for these machining (zig-zag machining parameter table) are: a) passes direction angle, that must be perpendicular to the block mounting axis. b) increment between passes. c) Increment of Z value, that represents the maximum height removable by the tool. d) Extension value of the passes. It is used to set a safety value to compensate possible closing position imperfections of block. A value can be suggested, for example, between 0.5 to 1 mm. The raw part dimensioning (the block) have not to be increased in its creation in order to grant “safe” values, because this value is used for that scope. We suggest to apply a next operation of <GRIND2> on both side of block, to remove the material eventually left from previous roughing, below the half of block size. This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> <GRIND3...> The machining with <GRIND1...>, in many points implies that the tool retracts to rotate and back down almost in the same position, to start the next pass. This "retraction" is executed for safety reasons, above all using machines without the TCP managing. When the machine allows safe rotation avoiding to move the tool away from the contact point, it is possible to set <GRIND3...> instead of <GRIND1...> in order to reduce the number of "retracts" (only those with inversion between two complete passes are removed). <GRIND4...> • This value allows for extra clearance outside of the part border to completely mill out the extra stock – therefore, leaving less material for the 180 side to rough out. This would not be recommended for finishing. – – This allows us to save time. Example Images below for Grind 4: <GRIND5...> • This value allows for the exact clearance of the Offset when machining around the part during the roughing or finishing steps. – – This is recommended for use when the Grind4 roughing has been applied to the initial step. The excess material from the blank will have been machined so we can save time by cutting less material in the 2nd roughing step and subsequent Finishing Steps. Examples of this are below: GRIND OPTION • <NCF1,0.5> Narrow Cavity Filter 1 = Cavity diameter (Measured in mm) 0.5 = Cavity depth (Measured in mm) Activates a “filter” for the Grinding Operation in order to recognize the small cavities on the surface of a restoration (This may include occlusal fishers, internal prep areas, or simply any concavity on the surface of a part). The tool may physically be able to fit within the area, but due to an excessive amount of vibration that would be caused from trying to machine within - these areas will be skipped and left to be milled with a subsequent tool (Usually a smaller diameter), thus reducing the stress on the tool & material. GRIND OPTION • <PD2.5,0.05,1,0.5> Previous Diameter 2.5 = Previous tool diameter 0.05 = Oversize left by the previous tool 1 = Cavity diameter (related to NCF of previous tool) 0.5 = Cavity depth (related to the NCF of previous tool) The machining become like a restmill so the tool will work only in the small cavity not machined previously. – Here is an example of how to use this code: <PLANEZ…> This feature has been superseded by the newer Grinding Operations <GRIND4> & <GRIND5> This a code is used for Glass Ceramics and Lithium Disilicate blocks. (For use with 3D PROFILE POCKETING only). It raises or lowers (relative to the Z=0 position) the depth of the toolpath in the Z axis. This parameter can be positive or negative (declared in mm) Samples: <PLANEZ-1> <PLANEZ1> <LEVEL> This code is used for disilicate blocks. It adds a flattening at the start of a roughing operation. Sample: INTERNAL ROUGHING PART1<TS1,2,8,9,10><GRIND4,0.15><LEVEL><R> <TA> For the 5 axis continuous machining of glass ceramic, to specify a value pair of "Tilting Angles" in the machining name <TA...,...>. For example: <TA5,10> means that you want the tool axis inclined by 5° along the working direction and 10° transversely to the cutting direction. The first value is meant to indicate a positive inclination toward the movement direction. The second value is meant to indicate a positive slope on the right side of the cutting direction. This code is used for the operation named: - zig-zag - bitangency - rest milling - XY contouring - pocketing Considering the frequent direction changes of toolpath in these kind of machining, it makes sense to refer only to the first of two angles associated with this code (the angle along the direction of movement) omitting the lateral angle to the direction of movement. However, the system apply the second angle (lateral angle) when indicated <CI…> (Only applies to Zig-Zag Machining) This code is used for Glass Ceramics or Lithium Disilicate blocks. It applies a ZIG-ZAG operation that will ensure a uniform surface texture on areas that could have excess material during the machining by applying an additional toolpath that is perpendicular with the current zig-zag toolpath. The numerical value is the distance between each step over to be applied on this additional toolpath. This overrides the “Constant scallop height traverse machining” value under Machining Parameters. Example: <CI0.05> (The step increment is 0.05mm) <BTH…/…> The acronym <BTH.../...> (Blank o Block Thickness) it is used to indicate that the operation can be executed only with stocks having the thickness between the set limit values. The first value specifies the minimum thickness and the second one the maximum. For instance <BTH0/10> or <BTH10.1/30> It is possible to set more than one code <BTH…/…> for the same machining.
