Material Removal Rate
Compute volume removal rate Q (MRR) from depth ap, feed f and speed v.
Inputs
Formula
Q = ap·f·v
Higher MRR usually trades off finish and tool life.
Fundamentals
Compute volume removal rate Q (MRR) from depth ap, feed f and speed v.
This tool computes Material Removal Rate from the formula: Q = ap·f·v
History
Manufacturing evolved with machine tools and CNC; cutting-parameter calculation is central to process planning.
Engineering applications
Used for cutting parameters, tooling and forming process design.

Formula
核心计算关系：Q = ap·f·v
输入变量：
- Depth ap
ap— mm - Feed f
f— mm/rev - Cutting speed v
v— m/min
输出结果：
- MRR Q
Q— cm³/min
假设/适用：Cutting params (v, f, a_p) must stay within tool/workpiece recommended windows.
Worked Example
根据公式 Q = ap·f·v，取 Depth ap = 2 mm；Feed f = 0.2 mm/rev；Cutting speed v = 100 m/min。
代入计算得：MRR Q = 40 cm³/min。
Key Points
- Cutting params (v, f, a_p) must stay within tool/workpiece recommended windows.
- MRR scales with feed speed, depth and width; sets required spindle power.
- Feed f = f_z·z·n; match per-tooth feed with spindle speed.
