RPM Range

Some turning centers have gear boxes that set the maximum spindle speed of the machine. The RPM Range list sets the gear box to a specific maximum range. If you set RPM Range to a value of 1-4, then the range is set explicitly. If RPM Range is set to Auto then FeatureCAM sets the range for you based on the following rules:

  1. If the feature is a turned Hole or another turned feature without Constant Surface Speed set, then the range is determined based on the Spindle Speed.
  2. If the feature is a turned feature with Constant Surface Speed set, then the range is determined based on the Max RPM.
