# 锯切进给：如何计算进给速度

锯切进给速度 = 每齿咬入量 × 齿数 × 转速。如何为圆锯和带锯计算进给速度，而不烧焦或闷车。

## 进给公式

进给速度 vf 等于每齿咬入量（fz）乘以齿数（z）乘以锯片转速（n）：vf = fz × z × n。对圆锯，结果为 mm/min；除以 1000 得到 m/min。

## 算例

一片 24 齿锯片在 4000 rpm、每齿咬入 0.05 mm 时：vf = 0.05 × 24 × 4000 = 4800 mm/min ≈ 4.8 m/min。硬木和高密度板需要更小的咬入量，软木可更大。

## 进给不对的迹象

太慢：烧焦、刃口釉化、变钝——锯片在摩擦而不是切削。太快：电机过载、跑偏、切面粗糙。干净的切屑和稳定的电机声，说明进给是对的。

## 带锯

带锯要用每齿咬入量、每米齿数和锯条线速度（m/min）来思考：vf = fz × 每米齿数 × 锯条速度。例如：0.05 mm 咬入、6 齿/cm、锯条 700 m/min → 进给 ≈ 21 m/min。

## 雕刻机与铣床的进给

铣削用的是同一个思路——每齿进给 × 刃数 × 转速。[进给与转速](https://nestingcalc.com/cn/feeds-speeds-calculator/) 按材料内置每齿进给预设，让雕刻机和 CNC 的进给与上面的锯切算法保持一致。
