3.5 Pocket cycle with a profile
A pocket is composed by an external contour or profile (1) and a series of internal contours or profiles
(2). These internal profiles are called islands.
• In 2D pockets (top left figure), all the walls of the outside profile and of the islands are vertical.
• In 3D pockets (top right figure), one, several or all the walls of the outside pocket and/or of the
islands are not vertical (up to a maximum of 4).
Programming 2D pockets with profile.
When defining the profile, one must indicate, besides the outside contour of the pocket, the contour
or contours of the islands.
The machining in Z is defined with the following parameters:
Zs Safety plane coordinate.
Z Part surface coordinate.
P Pocket depth.
I Step in Z.
Fz Penetrating feedrate in Z.
The following must be defined in the data area for the roughing operation:

The sideways penetration angle.

The milling pass.
The following must be defined in the data area for the finishing operation:

The sideways penetration angle.

Finishing stock on the side walls.

z Finishing stock at the bottom.
N Number of finishing passes in Z.
This key accesses the pocket-with-profile operation.
There are two types of pocket with profile; 2D and 3D.
