12.11 Circular pocket

Geometric parameters: 

Roughing parameters:

The roughing operation empties the pocket leaving the following
finishing stocks: 

Both stocks are defined as finishing parameters.

The roughing operation defining parameters are: 

Xc, Yc Center of the pocket.

R

Pocket radius.

Z

Part surface coordinate.

Zs

Safety plane coordinate.

P

Total depth.

δ

Finishing stock on the side walls.

δ

z

Finishing stock at the bottom of the pocket.

∆

Maximum milling pass or width.

The cycle recalculates the pass so that all the passes are
identical, with the same value as or smaller than the one
programmed.

If programmed with a 0 value, it assumes a value of 3/4 of the
diameter of the selected tool.
