5.3 Tool compensation

Tool radius compensation

The block for programming a tool movement contains:
RL or RR for radius compensation
R0 if there is no radius compensation
Radius compensation becomes effective as soon as a tool is called
and is moved with a straight line block in the working plane with RL
or RR.
The TNC automatically cancels radius compensation
if you:
program a straight line block with R0
depart the contour with the DEP function
program a PGM CALL
Select a new program with PGM MGT
For radius compensation, the TNC takes the delta values from both
the TOOL CALL block and the tool table into account:
Compensation value = R + DR
R: Tool radius R from the TOOL DEF block or tool table
DR Oversize for radius DR in the TOOL CALL block
:
TOOL CALL
DR Oversize for radius DR in the tool table
:
TAB
Contouring without radius compensation: R0
The tool center moves in the working plane along the programmed
path or to the programmed coordinates.
Applications: Drilling and boring, pre-positioning
