Cutting edge checking
Description
Before a tool is checked for missing teeth or excessive runout, it is
first set for radius/diameter. The diameter Cutting edge check cycle
then moves the rotating tool into the beam until the teeth interfere
with the beam by the cutting edge runout tolerance value. This value
is defined by the R06=k input.
The spindle speed is calculated from the minimum pulse signal delay
RENC[15] of the NC1 system and the number of teeth on the cutting
tool. This ensures that when each tooth enters the beam, a
permanent beam cut signal is held unless a tooth is either missing or
is out of tolerance. The beam cut signal is monitored for a minimum of
two revolutions.
