TC50

Number of times that the feed rate is to be reduced during the #4 and #5 cutting-off cycles of a grooving unit

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
What it does

Number of times that the feed rate is to be reduced during the #4 and #5 cutting-off cycles of a grooving unit

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 When 0 or 1 is set for TC50, the feed rate is unchanged.
