Programming:
„ Program constant surface speed G96
„ Program G991 and G1 (path before the parting operation or return
path) in one block.
„ Result in V300:
„ 0: Not cut off
„ 1: Cut off
Values for controlled parting G992
G992 overwrites MP 808, MP 858, ... for controlled parting. The new
parameters are effective from the next NC block and are retained until
G992 is reprogrammed or the parameters are edited.
„ Parting control with G917 is preferable to G991.
„ Tool breakage results in speed differences which in turn
might affect the monitoring result. It is therefore
advisable to monitor the reverse path too.
Parameters
S Speed difference (in revolutions per minute)
E Monitoring time (in ms)
