Cutting Speed

Surface speed at the contact point between tool edge and workpiece.

Cutting Speed

Definition

Surface speed at the contact point between tool edge and workpiece. Use this entry as a shop-floor reference, not as a detached textbook definition.

Formula / Rule

  • vc = (π × D × n) / 1000

Typical Range & Scenarios

  • Start from material family, then tune to stability.
  • Review the result against setup, rigidity, and inspection method.

Common Errors / Troubleshooting

  • If chips discolor early, speed may be too high.
  • Recheck state, datum, and measurement chain before editing offsets or code.

Source-grounded Evidence

  • 来源定义切削速度 VC 为刀具刃口相对工件表面的速度，并支持恒切削速度控制。
  • 来源说明在 G96 恒线速控制下，S 值表示切削线速度，系统会自动调整主轴转速维持恒定。
