Fig. 2-38 Retraction behavior with G460
The last block with active tool radius compensation (N20) is so short that an intersection no
longer exists between the offset curve and the preceding block (or a previous block) for the
current tool radius. An intersection between the offset curves of the following and preceding
blocks is therefore sought, i.e., between N10 and N30 in this example. The curve used for
the retraction block is not a real offset curve, but a straight line from the offset point at the
end of block N20 to the programmed end point of N30. The intersection is approached if one
is found. The colored area in the figure is not machined, although the tool used would be
capable of this.
G460
With G460, the approach/retraction strategy is the same as before.
