Constant Cutting Speed Gx96 - HEIDENHAIN CNC PILOT 640 User Manual

Constant cutting speed Gx96

The spindle speed is dependent on the X position of the tool tip or
on the diameter of the drilling or milling tool.
G96: Main spindle
Gx96: Spindle x (x: 1...3)
Parameters:
S: Cutting speed in m/min or ft/min
If you call a drilling tool while a constant cutting speed
is active, the control automatically calculates the
spindle speed from the programmed cutting speed and
activates it with Gx97. To prevent inadvertent rotation of
the spindle, program the
T.
