Tool radius compensation
The block for programming a tool movement contains:
RL
or
RR
for radius compensation
R0
, 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
RL
or
RR
.
The control automatically cancels radius compensation
in the following cases:
Straight-line block with
R0
DEP
function for departing from the contour
Selection a new program via
PGM MGT
For radius compensation, the control takes the delta values from
both the
TOOL CALL
block and the tool table into account:
Compensation value =
R
+
DR
TOOL CALL
+
DR
TAB
with
R
: Tool radius
R
from
TOOL DEF
block or tool table
DR
TOOL CALL
: Oversize for radius
DR
in the
TOOL CALL
block
DR
TAB
: Oversize for radius
DR
in the tool table
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
