Feed Rate

The speed at which a cutting tool advances along the workpiece in CNC machining, typically measured in mm/min (millimeters per minute) or IPM (inches per minute).

Feed Rate

Definition

The speed at which a cutting tool advances along the workpiece in CNC machining, typically measured in mm/min (millimeters per minute) or IPM (inches per minute). Use this entry as a shop-floor reference, not as a detached textbook definition.

Formula / Rule

  • vf = fz × z × n

Typical Range & Scenarios

  • Keep feed tied to chip evacuation and rigidity.
  • Review the result against setup, rigidity, and inspection method.

Common Errors / Troubleshooting

  • If finish drops, inspect runout before cutting feed.
  • Recheck state, datum, and measurement chain before editing offsets or code.

Source-grounded Evidence

  • 来源将进给速率定义为刀具中心点的运动速度，单位可为 mm/min，并可结合每刃进给与刀刃数计算。
  • 来源说明进给速度通过 F 代码控制，支持 G94 每分钟进给与 G95 每转进给两种模式。
