Cutting-length machining time
Inputs
User-entered total path length while cutting; entries, exits, repositioning, and toolpath strategy are not derived.
User-entered cutting feed rate; tool, material, speed, chip load, and quality are not selected or derived.
User-entered aggregate allowance for stated non-cut time; setup, handling, and machine motion are not predicted.

tcut = Lcut / Ffeed; ttotal = tcut + tallowance
A first-pass number, not a code check, certification, or approval. Read the method and its limits below. What this is and is not.

Method
Formula, when it applies, and when it does not
Divide cutting length by feed rate and add a non-cut allowance without selecting tools, cutting data, materials, machines, or process strategy.
tcut = Lcut / Ffeed; ttotal = tcut + tallowance
When
- One scalar cutting-time relation
Don’t
- This divides only user-declared cutting length by declared feed rate and adds a declared non-cut allowance. It does not select tools, feeds, speeds, materials, machines, or process strategy; calculate tool life, quality, cost, capacity, safety, suitability, or approval.
