8 Services from machining-calc.x402tookit.com

Returns the recommended tap drill size (metric and inch) for a specified thread, along with formula verification and thread dimensional data.

Calculates bend allowance, outside setback, bend deduction, and flat pattern length for sheet metal bends given angle, inside radius, material thickness, and K-factor.

Calculates ISO bolt preload force and tightening torque using T = K·F·d for property classes 8.8, 10.9, and 12.9

Calculates machining cut time in minutes and seconds for a given cut length, using either a direct table feed rate or RPM plus feed-per-revolution, with support for multiple passes.

Converts between spindle RPM and surface speed (SFM or m/min) for a given cutter or workpiece diameter.

Calculates ISO metric thread dimensions including pitch diameter, minor diameters (internal and external), thread height, and tensile stress area from a nominal diameter and pitch.

Calculates milling table feed rate from spindle RPM, number of flutes, and chip load per tooth — or back-calculates chip load from a given feed rate.

Calculates metal removal rate (MRR) for milling (width × depth × feed) or turning (surface speed × feed × depth of cut) in imperial or metric units.
