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

Measured MRR (in3/min, optional) Known cycle (min/part, optional)

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.
