Manufacturer-reference beta. Table transcription and arithmetic have been checked. Machinist application review and cutting trials are pending. Results are starting data, not a machine-approved setup.
Current coverage: M.A. Ford 277 / 277N / 277W profile milling in three steel conditions; Sumitomo AC8020P steel turning with NFE, NLU and NMU chipbreakers. Metric inputs. Other tools and materials are not covered.
Use actual tool and machine limits for your setup.
RPM, FEED & SOURCE
Your starting cut.

KNOW WHAT THE NUMBER MEANS
Table data in.
A traceable starting point out.
The calculator selects cutting speed and feed from a specific manufacturer row. It converts cutting speed into spindle RPM, applies your entered RPM limits, then calculates feed from the resulting RPM. The result shows what was selected and whether your entered feed limit is exceeded.
Milling uses feed per tooth and your effective flute count. Turning uses feed per revolution. The two calculations have separate tool, material and depth requirements.
Match the actual tool and material
Milling covers eight exact diameters from 3 to 20 mm and four radial-engagement columns. Turning covers six insert-size families. Confirm the complete insert designation and application. Hardness means the material’s condition when it is cut, before any later heat treatment.
What is checked
Selected table coverage, positive inputs, entered RPM and feed limits, milling depth versus cutting length, and the transcribed depth and hardness conditions. No interpolation or substitute tool data is applied.
What still needs application review
Available spindle power, holder and stickout, workholding, coolant, interrupted cuts and other setup conditions. This beta does not calculate force, power, deflection, temperature, chatter, tool life or a finish guarantee. Review the source and setup before cutting.
