5.3 Entering Electrode-Related
Data
Introduction
Besides the electrode data and compensation you must also enter the
following information:
„
Feed rate F
„ Miscellaneous functions M
Feed rate F
The feed rate is the speed (in millimeters per minute or inches per
minute) at which the electrode center moves. For eroding, the feed
rate is defined by machine parameters. It can also be selected for
positioning with eroding.
Input range:
F = 0 to 30 000 mm/min (1 181 inch/min)
The maximum feed rates can be different for the individual axes and
are set in machine parameters.
Input
Answer the dialog question in the positioning block:
Enter the feed rate, for example F = 100 mm/min.
Rapid traverse
For rapid traverse you can enter F = FMAX. The rapid traverse can also
be programmed directly.
FMAX is only effective in the program block in which it is programmed.
Duration of feed rate F
A feed rate entered as a numerical value remains in effect until the
control encounters a block with a different feed rate. If the new feed
rate is FMAX, then after the block with FMAX is executed, the feed
rate will return to the last feed rate entered as a numerical value.
Feed rate override
You can adjust the feed rate with the override knob on the TNC
keyboard.
