4.2 Programming example for the pocket on a structur-
al part
Inclined inner and outer walls are a typical feature of structural parts. The most effective way to
create these is to use the circumferential milling technique. The following programming example
relates to the milling of a pocket with inclined walls. It illustrates the functions required to achieve
this, such as orientation interpolation and tool radius compensation, by showing what actually
happens in practice.

; Activate TRAFO
; Select tool zero
; Shift tool zero to center of pocket!
; (Rotate pocket if required)
; Tool orientation in WCS
; Large circle interpolation of orientation
; 3D tool radius compensation (TRC)
; Insertion depth of tool = 0
; The contour has been programmed on the pocket floor,
; not on the workpiece surface
