14.3 CUTTER COMPENSATION
When the tool is moved, the tool path can be shifted by the radius of the
tool.
To make an offset as large as the radius of the tool, CNC first creates an
offset vector with a length equal to the radius of the tool (start-up).
The offset vector is perpendicular to the tool path. The tail of the vector
is on the workpiece side and the head positions to the center of the tool.
If a linear interpolation or circular interpolation command is specified
after start-up, the tool path can be shifted by the length of the offset
vector during machining.
To return the tool to the start position at the end of machining, cancel the
cutter compensation mode.
