7.5.5 3D tool offset: Inside/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.
