Data from the erosion table
When you are working with an erosion table, the following erosion
parameters are also available in Q parameters.
Q parameters when not using erosion tables:
Q90 to Q99
If you are working without erosion tables, you must use the
Q parameters for eroding (Q90 to Q99).
The machine tool builder can give you more information about these
Q parameters.
Electrode data: Q108, Q158 to Q160
The TNC stores the electrode data that you entered in the TOOL DEF,
TOOL CALL and EL-CORR blocks in the following Q parameters:
Erosion parameters Parameters
