Where : Is :
XY
The coordinates thatspecify the centerofthecircularpost.
Z
The coordinate (along the plungingaxis)thatspecifies the bottomofthe circular
pocket.
R
The radius of thecircular post. This parameter mustbe programmed.

circularpostto the outer perimeterofthecircularpocket.
P
Directionofroughing cut.
H
Finishallowance.
D
