Tool radius compensation(G40~G42)
Tool radius compensation codes can move the tool just with the offset of tool radius, shown as Fig. 3-42.
To make the offset value the same with the radius value, the system needs to build up a offset vector
(start tool), whose length equals to the tool radius.
The direction of the offset vector is perpendicular to that of tool motion, with part pointing at the tool
center.
If linear interpolation or circular interpolation is schemed after tool start, tool offsets in certain vector and
then starts machining.
Finally, cancel the tool radius compensation to move the tool back to the origin.

Tool compensation types
Tool (cutter) compensation should be established before executed and cancelled after workpiece
machining completed. To establish tool compensation is to move the tool to the edge of workpiece in a
reasonable way, while to cancel tool compensation is to move the tool to the specified point from the
edge of workpiece.
Generally, establishment of tool compensation includes two establishing segments, as segment 1 and 2
in Fig. 3-43.This software offers 3 types of establishing tool compensation.
1) Normal type: the programming path is translated by 90 degrees to get the segment 2 for
establishment, next, make the starting point of segment 2 the end point of the segment 1. Segment
1 and 2 constitute the tool nose path with tool radius compensated. Please note that this type is not
