4.11 HOW TO PROGRAM A LATHE WITH THE BARFEEDER
There are many ways of programming a lathe with the barfeeder SS2400T/S. Generally, the
End of Bar test should be in the program before feeding to ensure that an arbitrarily long bar
can be clamped in the lathe at start of the automatic cycle.
4.11.1 FEEDING TO STOPPER
If end of bar is not reached, the barfeeder moves the bar to the stopper in the tool head. The
arrival at the end of bar initiates the bar replacement subprogram.
Main program (feeding)
5. Tool head departure to the tool replacement position
6. Alignment of the tool head stopper with the spindle axis
7. Spindle stop
8. End of bar test (at end of bar, jump to subprogram for new bar loading)
9. Stopper arrival in front of the cut-off bar
10. Clamping device opening
11. M-code (the barfeeder pushes the bar to the stopper)
12. Stopper departure to the machining position (the barfeeder continues to push the bar to
the stopper)
13. Clamping device closing (the barfeeder returns)
14. Dwell for pusher retraction to the rear position
15. Tool head departure to the tool replacement position
16. Technological program
17. Jump to program start
Subprogram (new bar loading)
50. Spindle positioning (necessary for non-circular sections)
51. Clamping device opening
52. M-code (the barfeeder ejects the rest)
53. 8 s dwell for ejection evaluation
54. Stopper arrival in front of the clamping device
55. M-code (the barfeeder pushes the new bar to the stopper)
56. Stopper departure to the position for new bar squaring
57. Clamping device closing (the barfeeder returns)
58. Dwell for pusher retraction to the rear position
59. Tool head departure to the tool replacement position
60. Tool replacement
61. New bar squaring
62. Tool head departure to the tool replacement position
63. Stopper selection
64. Return from the subprogram to line 5
