Tool call
Just as in Milling mode, turning tools are called with the TOOL CALL
function. You merely have to enter the tool number or tool name in the
TOOL CALL
block.

Tool compensation in the program
With FUNCTION TURNDATA CORR you can define additional compensation
values for the active tool. In FUNCTION TURNDATA CORR you can enter
delta values for tool lengths in the X direction DXL and in the Z direction
DZL
. The compensation values have an additive effect on the
compensation values from the turning tool table. FUNCTION TURNDATA
CORR
is always effective for the active tool. A renewed TOOL CALL
deactivates compensation again. When you exit the program (e.g.
PGM MGT), the TNC automatically resets the compensation values.
