Description
Number of times that the feed rate is to be
reduced during the #4 and #5 cutting-off
cycles of a grooving unit
Program type M
Conditions Immediate
TC50
Unit Times
Setting range 0 to 65535
The staring feed value for cutting-off is a feed value that has been
designated in unit data, and the ending feed value for cutting-off is a feed
value that has been designated in sequence data. The feed rate from the
start of machining to the end is reduced in steps according to the number
of times that has been designated here.
Example:
Feed rate set at feed item in unit data = 0.5
Feed rate set at roughness item in sequence data = 0.1
TC50 = 3
Workpiece
Workpiece
Feed rate: 0.5
Feed rate: 0.3
Feed rate: 0.1
When 0 or 1 is set for TC50, the feed rate is unchanged.
