(5)Cutting start point for a cuttingoff process (B option for the automatic
process determination function)
The cutting start point for a cuttingoff process is determined as shown
in Fig.a when there is no C/R (chamfer/corner R) at the cutoff section
and as shown in Fig.b when there is a C/R at the cutoff section.

there is no C/R at the cutoff section
Fig. b Cutting start point when
there is a C/R at the cutoff section
(6)Division direction for inverse processes (B option for the automatic
process determination function)
The division direction at division point DS for an inverse process is
one of the following three types (outer surface machining is taken as
an example):
Division starts at point j, proceeds toward
the subedge of the inverse tool, and inter-
sects first with the part figure
Division starts at point j, proceeds toward the
subedge of the inverse tool, and intersects with
the material figure at less than two points
Division starts at point j, proceeds toward the
subedge of the inverse tool, and intersects with
the material figure at two or more points
