Tool radius compensation
The NC block for programming a tool movement contains:
■
RL or RR for compensation in the tool radius
■
R+ or R– for radius compensation in single-axis movements
■
R0 if no radius compensation is required
Radius compensation becomes effective as soon as a tool is called
and is moved in the working plane with RL or RR.
The TNC cancels radius compensation if you:
■
program a positioning block with R0
■
depart the contour with the DEP function
■
program a PGM CALL
■
select a new program with PGM MGT
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
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
Tool movements without radius compensation: R0
The tool center moves in the working plane to the programmed
path or coordinates.
Applications: Drilling and boring, pre-positioning
(see figure at right)
Tool movements with radius compensation: RR and RL
RR
The tool moves to the right of the programmed contour
RL
The tool moves to the left of the programmed contour
The tool center moves along the contour at a distance equal to the
radius. “Right” or “left” are to be understood as based on the
direction of tool movement along the workpiece contour (see
illustrations on the next page).
