Milling Contour Pocket (Cycle63) - Siemens SINUMERIK 840D sl Operating Manual

8.5.10

Milling contour pocket (CYCLE63)

Function
You can use the "Mill pocket" function to mill a pocket on the face or peripheral surface.
Before you remove stock from the pocket, you must first 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
(climbing or conventional). If an island is located in the pocket, the cycle automatically takes
this into account during stock removal.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
Machining type
For solid machining, you can select the machining type (roughing or finishing). 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 when the cycle is called for the
second time.
During insertion with oscillation, the message "Ramp path too short" will appear if the tool is
less than the milling cutter diameter away from the insertion point along the ramp. If this
occurs, please reduce the angle of insertion.
