Inside Corners/Outside Corners And Intersection Procedure (G450/G451) - Siemens SINUMERIK 840D sl Programming Manual

Description
Pocket milling with inclined side walls for circumferential milling with CUT3DC
In this 3D tool radius compensation, a deviation of the mill radius is compensated by infeed
toward the normals of the surface to be machined. The plane in which the face end of the
mill is located remains unchanged if the insertion depth ISD has remained the same. For
example, a mill with a smaller radius than a standard tool would not reach the pocket base,
which is also the limitation surface. For automatic tool infeed, this limitation surface must be
known to the control, see section "3D circumferential milling with limitation surfaces".
For more information on collision monitoring, see
Literature: /PG/ Programming Manual Fundamentals, "Tool Offsets" section.
8.5.5

Inside corners/outside corners and intersection procedure (G450/G451)

Function
Inside corners/outside corners
Inside and outside corners are handled separately. The terms inner corner and outer corner
are dependent on the tool orientation.
When the orientation changes at a corner, for example, the corner type may change while
machining is in progress. Whenever this occurs, the machining operation is aborted with an
error message.
