Comment
; Load tool with e.g. five teeth ($TC_DPNT = 5).
; Change G95 F... to G95 FZ..., tooth feedrate active with
0.02 mm/tooth.
Comment
; Tool in spindle 4 (not the master spindle).
; Tooth feedrate 0.5 mm/tooth dependent upon spindle S4.
Comment
; Tooth feedrate 0.03 mm/tooth
; Load tool with e.g. seven teeth ($TC_DPNT = 7).
; Effective revolutional feedrate 0.21 mm/rev
; Load tool with e.g. five teeth ($TC_DPNT = 5).
; Tooth feedrate modal 0.03 mm/tooth,
effective revolutional feedrate 0.15 mm/rev
Comment
; Spindle 1 is the master spindle.
; Tool 3 is changed to spindle 1.
; Speed S400 of spindle 1 (and therefore T3).
; Tooth feedrate 0.03 mm/tooth
; Path motion, the effective feedrate is dependent upon:
- The tooth feedrate FZ
- The speed of spindle 1
- The number of teeth of the active tool T3
; Spindle 2 becomes the master spindle.
; Tool 1 is changed to spindle 2.
; Speed S500 of spindle 2 (and therefore T1).
