Further information
Path and orientation
The type of circumferential milling used here is implemented by defining a path (guide line) and
the associated orientation. In this type of machining, the shape of the tool on the path is not
relevant. Only the radius at the tool intervention point is decisive.

Comment
; Definition of tool D1:
; Type (end mill)
; Length compensation vector
; Radius
; Selection of the tool.
; Activation of the transformation.
; Activation of the 3D circumferential milling,
; continuous orientation changes at outside corners,
; insertion depth: 10 mm
; Orientation change at a corner through specification of axis po-
sitions.
; Traversing block with orientation change,
; specification of the orientation with direction vector.
; Traversing block with constant orientation.
; Traversing block with orientation change.
; Block without traversing information.
; Traversing block with change of the insertion depth.
; Deactivation of the tool radius compensation.
