The "Mill pocket" function is used when you want to mill a pocket on
the end face or peripheral surface.
Before you can program stock removal from the pocket, you must
enter the contour of the pocket and, if applicable, the contour of an
island.
Stock is removed from the pocket parallel to the contour from the
inside to the outside. The direction is determined by the machining
direction (climb/conventional) (see "Changing program settings").
If an island is located in the pocket, ShopTurn automatically takes this
into account during stock removal.
You can select the machining mode (roughing or finishing) for
removal. If you want to rough and then finish, you have to call the
machining cycle twice (Block 1 = roughing, Block 2 = finishing). The
programmed parameters are retained on the second call. For further
details on finishing, please read the Section "Finishing the contour
pocket".
Press the "Milling", "Contour milling" and "Pocket milling" soft
Contour
keys.
