MfgWorkbench: Formula-First Shop-Floor Calculators

mfgworkbench.com Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

A manufacturing reference with calculators for machining parameters, tap drills, material-removal rates, chip thinning, and related production math.

Landing page captured for the 2026-09-04 issue.

Field notes

The site turns recurring shop-floor calculations into separate tools with explicit inputs and visible units. Its milling calculator covers spindle RPM, table feed, and chip load, while the machining-time tool accounts for approach, rapids, and tool changes rather than only cutting distance. A reference layer explains equations such as the surface-speed formula and includes a metric/UNC/UNF tap-drill chart, positioning the site as both a calculator set and a reviewable technical reference.
