  • Default value: Yes

Max Speed of Ref Circle

  • When an arc is machined, the machine tool will vibrate due to centripetal force. To reduce this kind of vibration, the software limits machining speed during machining an arc in terms of centripetal acceleration.
  • Take default setting as an example, the maximum line velocity of the reference circle (diameter: 10mm) is 1800mm/min. The formula to calculate centripetal acceleration is α=v²/r; among it, r=(10/2)mm, v=1800mm/min. Thus centripetal acceleration α can be calculated; when other arcs are processed, this centripetal acceleration is the maximum allowable centripetal acceleration. Arc apeed will be limited if it is too large causing centripetal acceleration larger than α calculated in this formula.

  • Default value: 5000
