ool Compensation
Tool radius compensation
The NC block for programming a tool movement contains:
n
RL
or
RR
for radius compensation.
n
R+
or
R–
, for radius compensation in single-axis movements.
n
R0
, if there is no radius compensation.
Radius compensation becomes effective as soon as a tool is called
and is moved in the working plane with RL or RR.
For tool radius compensation, the TNC takes the delta values from
both the
TOOL CALL
block and the tool table into account:
Compensation value =
R
+
DR
TOOL CALL
+
DR
TAB
where
Contouring without radius compensation: R0
The tool center moves in the working plane to the programmed path
or coordinates.
Applications: Drilling and boring, pre-positioning.
The TNC automatically cancels radius compensation if
you:
n
program a positioning block with
R0
n
depart the contour with the
DEP
function
n
program a
PGM CALL
n
select a new program with PGM MGT
R
is the tool radius
R
from the
TOOL DEF
block or tool
table.
DR
TOOL CALL
:
is the oversize for radius
DR
in the
TOOL CALL
block
(not taken into account by the position display).
DR
TAB
is the oversize for radius
DR
in the tool table
