Spindle speed clamp value in cutting off cycle

Q: What does Mazak parameter TC49 do?

TC49 is a User parameter in the TURNING group of the MAZATROL SmoothX control (INTEGREX e-670H). Spindle speed clamp value in cutting off cycle (GRV). If 0 or 1 is set up in TC50: This value will be used as the spindle speed clamp value in cutting off cycle (#4/#5). If 2 or more is set up in TC50: Immediately before the cutting off area (*) is reached during the cutting off cycle, this value will be used as the spindle speed clamp value. Within the cutting off area, however, machining will be executed at the speed corresponding to this value. *: Cutting off area = (Starting position X – Ending position X) × TC9/100 TC49 = 0: The spindle speed will be clamped with the RPM value in the common unit. If RPM is zero, the spindle speed will be clamped with the value of parameter SA1.

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.
