Interactive machining calculator

It is a shop-floor calculator where Vc, diameter, RPM, feeds and pass time are linked: move any value and the rest recalculate instantly. It has three modes — milling, turning and drilling — with locks to pin whatever you don't want to change.

n = (1000 · Vc) / (π · D). If you know two of the three (cutting speed, diameter or spindle speed), the calculator finds the third. Units: Vc in m/min, D in mm, n in 1/min. Applies equally to a milling cutter, a turned part or a drill.

In milling: vf = fz · z · n (fz feed per tooth, z teeth). In turning and drilling: vf = f · n, with f in mm/rev. If you enter vf, fz (or f) is solved keeping the rest; with the lock you can pin whatever you don't want to change.

tc = lf / vf (minutes). lf is the cutting distance including entries and exits (in drilling, the depth). If you set a target time, the distance equivalent to that progress is adjusted.

From the GetGCode materials catalog: you choose the material, the tool material (HSS or carbide) and the type of cut, and indicative Vc and feed are proposed. Always adjust for clamping, overhang and machine condition.

The chip flow rate Q (cm³/min) and the cutting power P = Q·kc/60000 with an indicative kc per ISO group. If you indicate the kW of your spindle, it warns you when the cut requires more power than you have.

The cutting parameters calculator recommends the starting point (Vc, feed, roughness, threading) by material and tool. This interactive calculator is for adjusting those quantities live at the machine: linked scales, locks, your machine's limits and pass time.

Yes. The calculation runs in the browser, without registration. The latest values ​​for each mode are saved on the device, and you can share a link that opens the calculator already set to your values.
