切断侧工件的最大加工径φD1（图-3）φD1=Dmax从程序上来讲，如图-4所示刀尖超过
工件的中心后工件落下，所以刀片和工件不会产生干涉。
（刀片和工件的最大加工径的清除值的半径值为0.2mm）

D1=Dmax. Even
if
the
cutting
edge
runs

the

the
workpiece,
since
the

(The

between
the
insert
and
the
work
is
0.2mm)
进行该加工的时候即使刀尖到达工件的中心的时候工件也不会掉落，刀尖越
工件的中心后刀片会和工件发生干涉，最大加工径也会改变。
例）程序上，进行如图-6所示刀尖越过工件中心1mm的设定的情况下切断
侧的工件的最大加工径φD2（图-6）
φD2=〔φDmax-1mm×2〕(mm)

In
this
case,
when
the
cutting
edge
runs
beyond

center
line,
the
insert
will
contact
the
workpiece,
since
the
workpiece

Therefore
the
programmed

must
be
considered.
When

(Max.

is
