Dear Answer Man,
We need to know about your bar feeder. Can it make two different, alternating pushes? I need to turn 2-inch–long and 3-inch–long pieces from the same bar stock. Can I alternate them?
Yes, you can do multiple bar pushes with the Haas Servo Bar 300. The I, J, and K commands will override the macro variables for the program line in which they occur (the macro values in Current Commands will not change). The J code is for part length plus cut-off, so to feed 2.0 inches of bar stock would require the line G105 J2.0.
Sincerely, Answer Man
