Calculate CNC is the machinist's shop-floor toolkit, and the only one that turns a part you sketch into real lathe G-code. THE PROGRAM PROTOTYPER Sketch a turned profile right on your phone. OD, ID, grooves, tapers, fillets, and Calculate CNC posts out Fanuc G-code you can take straight to the control. Lay in roughing and finishing passes, facing, grooving and drilling, preview the profile, and export the program. No CAM seat, no desktop, no $2,000 software. Just your phone on the bench. Then back it up with 40+ calculators and reference charts. Every formula and chart is checked against published standards (ASME, ISO, ANSI, Machinery's Handbook), so you can trust the number, then verify before you cut. Works fully offline. No account, no sign-up, no ads, no tracking.
