(8)If the last cut exceeds a depth of cut in inner surface roughing (No. 2)
In inner surface roughing in which a cutting area is divided as shown
in Fig. 2.5 (d), the blank figure is cut in such a way that the last tool
path goes along with the figure of the part. If the taper angle of the
figure is large, the last cut may exceed the depth of cut made by one
cut.
This occurs under the following conditions:
À At the cutting area division point (DS), part elements before and
after the division point intersect at an acute angle.
Á The arrow dividing the cutting area overlaps with the blank figure.
For these conditions, take either of the following measures:
À Make a slight chamfer at the division point (DS) (as a measure for
condition À).
Á Divide the cutting area in outer surface machining, which precedes
inner surface machining, as shown in Fig. 2.5 (e) (as a measure for
condition Á).
