Tool radius compensation
The block for programming a tool movement contains:
G41
or
G42
for radius compensation
G40
, if there is no radius compensation
The radius compensation is effective as soon as a tool is called and
traversed with a straight line block in the working plane with
G41
or
G42
.
The TNC automatically cancels radius compensation
if you:
program a straight line block with
G40
depart the contour with the
DEP
function
Select a new program with
PGM MGT
For radius compensation, the TNC takes the delta values from both
the
T
block and the tool table into account:
Compensation value =

Contouring without radius compensation: G40
The tool center moves on the machining plane along the
programmed path orto the programmed coordinates.
Applications: Drilling and boring, pre-positioning
