Cutting Time Calculator

Calculate cutting time by dividing total tool path length by feed rate, then multiply by number of passes. Add rapid traverse time, tool change time (typically 15-30 seconds per change), and setup time. Add 10-20% buffer for real-world conditions. This calculator automates these calculations.

Machining time (or cutting time) is the time the tool is actually cutting material. Cycle time includes machining time plus rapid moves, tool changes, and other non-cutting operations. Total job time adds setup time to cycle time multiplied by quantity.

Estimates are typically within 15-25% of actual times for simple operations. Complex geometries, material variations, and machine differences can affect accuracy. Always add buffer time for quoting and track actual times to improve future estimates.

Feed rate has the biggest impact on cutting time. Doubling feed rate roughly halves cutting time (if other factors allow). Tool path efficiency, number of passes (depth of cut), and machine rapid rates also significantly affect total job time.

Optimize feed rates for material/tool combination, reduce tool changes by using tooling that can perform multiple operations, minimize rapid distance with efficient tool paths, use high-speed machining strategies where appropriate, and consider tooling investments that allow higher speeds.

Yes, always include setup time. First-article setup takes longer than repeat jobs. For small quantities, setup time often exceeds machining time. Track your actual setup times to quote accurately. Consider offering price breaks for larger quantities where setup is amortized.
