8.1 Tangential control (TANG, TANGON, TANGOF, TLIFT, TANGDEL)
Comments
; 1. Defining the tangential tracking.
; Activating the coupling.
; Radius
; Deactivate the 1st coupling.
; Delete the 1st definition.
; 2. Defining the tangential tracking.
; Activating the new coupling
Comments
; Y1 is geometry axis 2.
; Deactivating tracking with Y1.
; Delete the 1st definition.
; Y2 is the new geometry axis 2
; 2. Defining the tangential tracking.
; Activating tracking with the 2nd definition.
