NO.
Programs:
N0 G92 X0 Y0 Z0; Tool are positioned at start position X0, Y0 and Z0 when the absolute
coordinate system is specified
N1 G90 G17 G00 G41 D07 X250.0 Y550.0; Start-up cutter, the tool is shifted to the tool path by
the distance specified in D07, geometric radius of
D07 is set to 2.0mm, tool wearing 0, then the tool
radius is 2mm.

Volume I
Perform tool setting in the mode of offset cancellation, after finishing the tool setting, and set the
tool radius D in OFFSET page.

6.2 Offset Path Explanation for Cutter Radius Compensation
6.2.1 Conception for inner side or outer side
“Inner side” and “outer side” will be employed in the following explanations. When an angle
of intersection created by tool paths specified by move commands for two blocks is over or equal
to 180°, it is referred to as “inner side”. When the angle is between 0° and 180°, it is referred to
as “outer side”.
