(21) If the tool escapes to the position blank figure inner surface +
clearance” in inner surface roughing
If the cutting end point (point C in Fig. 2.5 (ag)) is on the blank
figure, the specification states that the tool is to escape to the position
blank figure inner surface + clearance in the Xaxis direction.
This is intended to keep the tool from interfering with the workpiece.
In other words, the tool is moved in the xaxis direction because it
is determined that if the cutting end point is on the blank figure, the
tool interferes with the blank figure when it escapes in the Z–axis
direction. Even if the cutting end point is on the blank figure,
moving the tool in the Zaxis direction will output a tool path where
the tool crosses the blank figure in the case shown in Fig. 2.5 (ah).
