Cutting setup
Set starting parameters before a trial cut.
CNC calculator workbench
CNC Calculator Workbench
Use free CNC calculators for feeds and speeds, machining time, cost, ROI, TCO, and machine readiness checks. Start with the shop question in front of you, then move into the next release calculation.
4
Quote and capacity
Turn time and cost assumptions into a release number.
Machine readiness
Check the machine, power, and maintenance assumptions.
Continue from a first result
Use these follow-up paths when the first calculation needs power, tooling, cost, or tax validation.
Check spindle loadFeeds -> PowerAfter speed, feed, and MRR look plausible, verify horsepower before quoting or trial cutting.
Price the jobTime -> CostAfter cycle time is credible, turn setup, machine time, tooling, and overhead into a quote screen.
Estimate tool-life riskCutting -> LifeAfter cutting data is set, check Taylor tool-life exposure before approving unattended runs.
Model tax timingROI -> TaxAfter ROI and TCO are reasonable, separate depreciation timing from the operating case.

Procurement gate
Use positioning accuracy language when a shortlist needs acceptance-test evidence.
Cutting speed formulas
Engineering reference
Check SFM, RPM, feed, and chip-load formulas before releasing parameters.
