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.
When you enter the function

FUNCTION TURNDATA CORR you can

specify by soft key the effect of the tool compensation:

FUNCTION TURNDATA CORR-TCS: The tool compensation is

effective in the tool coordinate system
FUNCTION TURNDATA CORR-WCS: The tool compensation is

effective in the workpiece coordinate system

Tool compensation

FUNCTION TURNDATA CORR-

TCS is always effective in the tool coordinate system,

even during inclined machining.
