## What is 数控快算?

At the lathe, the slow part is often lookup and hand math—not cutting. CNC QuickCalc puts shop-floor calculations and reference G-code on your phone. Enter parameters, get coordinates and macro skeletons, copy in one tap.

WHY IT FITS REAL SHOP WORK
• Fully offline—no login; data stays on device
• 18 cut-point scenarios: OD, bore, and profile with tool-nose compensation
• Machine presets: FANUC, GSK, KND, Syntec headers
• One-tap copy for quick entry at the machine
