Description of function
Table for workpiece materials WMAT.tab
In the table for workpiece materials WMAT.tab, you define the workpiece material. You must save this table in the TNC:\table folder.
The table for workpiece materials WMAT.tab provides the following parameters:
Parameter | Meaning |
---|---|
WMAT | Workpiece material (e.g., aluminum) Input: Text width 32 |
MAT_CLASS | Material class Categorize the materials into material classes with the same cutting conditions (e.g., in accordance with DIN EN 10027-2). Input: 0...9999999 |
Table for tool materials TMAT.tab
In the table for tool materials TMAT.tab, you define the tool material. You must save this table in the TNC:\table folder.
The table for tool materials TMAT.tab provides the following parameters:
Parameter | Meaning |
---|---|
TMAT | Tool material (e.g., solid carbide) Input: Text width 32 |
ALIAS1 | Additional designation Input: Text width 32 |
ALIAS2 | Additional designation Input: Text width 32 |
Cutting data table *.cut
In the cutting data table *.cut, you assign the matching cutting data to the workpiece materials and the tool materials. You must save the table in the TNC:\system\Cutting-Data folder.
The cutting data table *.cut provides the following parameters:
Parameter | Meaning |
---|---|
NR | Sequential number of the table rows Input: 0...999999999 |
MAT_CLASS | Workpiece material from the WMAT.tab table Table for workpiece materials WMAT.tab Selection by means of a selection window Input: 0...9999999 |
MODE | Machining mode (e.g., roughing or finishing) Input: Text width 32 |
TMAT | Tool material from the table TMAT.tab Table for tool materials TMAT.tab Selection by means of a selection window Input: Text width 32 |
VC | |
FTYPE | Type of feed:
Input: FU, FZ |
F | Feed rate value Input: 0.0000...9.9999 |
Diameter-dependent cutting data table *.cutd
In the diameter-dependent cutting data table *.cutd, you assign the matching cutting data to the workpiece materials and the tool materials. You must save the table in the TNC:\system\Cutting-Data folder.
The diameter-dependent cutting data table *.cutd provides the following parameters:
Parameter | Meaning |
---|---|
NR | Sequential number of the table rows Input: 0...999999999 |
MAT_CLASS | Workpiece material from the WMAT.tab table Table for workpiece materials WMAT.tab Selection by means of a selection window Input: 0...9999999 |
MODE | Machining mode (e.g., roughing or finishing) Input: Text width 32 |
TMAT | Tool material from the table TMAT.tab Table for tool materials TMAT.tab Selection by means of a selection window Input: Text width 32 |
VC | |
FTYPE | Type of feed:
Input: FU, FZ |
F_D_0...F_D_9999 | Feed rate value for the respective diameter You don't need to define all columns. If a tool diameter is between two defined columns, the control linearly interpolates the feed rate. Input: 0.0000...9.9999 |
Note
In the corresponding folders, the control provides sample tables for automatic cutting data calculation. You can customize theses tables and specify your own data, i.e. materials and tools to be used.
