Use the G88.3 post milling roughing cycle to rough out a circular post in a
workpiece. This cycle makes multiple circular cuts at a programmed width
and depth.
The G88.3 block used to rough out a circular post has this format:
G88.3
X__Y__Z__R__Q__P__H__D__L__E__F__;
Where :
Is :
X Y
The coordinates that specify the center of the circular post.
Z
The coordinate (along the plunging axis) that specifies the bottom of the circular
pocket.
R
The radius of the circular post. This parameter must be programmed.
Q
Unsigned incremental value that specifies the distance from the sides of the
circular post to the outer perimeter of the circular pocket.
P
Direction of roughing cut.
H
Finish allowance.
D
Roughing cut thickness.
L
Incremental plunge depth.
E
Plunge feedrate.
F
Roughing feedrate.
