PROGRAMMING

G94 Feed per Minute

By G94 all F (feed) values are in mm/min (inch/min).

G95 Feed per Revolution

By G95 all F (feed) values are in mm/revolution (inch/

revolution).

G96 Constant Cutting Speed

Unit: m/min feet/min

The control computes the spindle speed for the

actual diameter continuously.

With diameters decreasing to 0 the speed should

increase to infinite.

In fact it increases to the maximum speed of the

machine and the program runs on without alarm.

If the maximum speed is to high (e.g.: limited chuck

speed, unbalanced work pieces, ...) G92 has to be

programmed additionally to delimit the speed.

Feed is automatically set to G95 (mm/rev, inch/rev).

No zero offset in X direction must be active.

G97 Constant Spindle Speed

Unit: rev/min

G96 will be deselected and the spindle speed will be

holded at the last valid value. Afterwards S will be

programmed in rev/min.
