Cycle time estimator.

Rough machining cycle time per part — based on stock envelope, removal percentage, material-specific MRR, feature complexity, and setup. Planning-grade estimates, not formal quotes.

Units: Inches Millimeters

Stock envelope (rough cube before machining)

Width Length Height

Material removal estimate %

Rough percentage of stock that becomes chips. Block 10-20%, frame/bracket 30-50%, deep-pocketed 60%+, hogged-out 80%+.

Material

Feature complexity

Simple = pocket + holes. Medium = many features, multiple tools. Very complex = 5-axis surfaces, tight tolerances, multiple finishing passes.

Setup time (hours) Run quantity

Rough estimate only. Actual cycle times depend on geometry specifics, fixturing, tool selection, and machine capability. Use this for sanity-check planning — request a formal quote for production-grade numbers.
