How do I simulate a CNC toolpath?

Open this page and use the live Lead–Lag Compensator tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a CNC toolpath from your own measurements.

Zero (rad/s)

Pole (rad/s)

A lead compensator (pole above zero) adds phase near the crossover to boost stability margins and speed; a lag compensator (pole below zero) trades phase to raise low-frequency gain and kill steady-state error. Educational tool.

Max phase shift55°

At frequency3.16 rad/s

Governing equation

C (s) = \frac{1 + s /1.0}{1 + s /10.0}

Reading this result: Pole above zero makes this a lead network: it injects up to 55° of phase near 3.2 rad/s, widening the stability margin and speeding the response right where the loop crosses over.
