CNC Lathe Assistant

Built for lathe work at the machine. Calculate threads, taper and arc coordinates, get conservative feeds and speeds, review risks, and copy reference code offline.

CNC Lathe Assistant is an offline tool built for real lathe work at the machine.

It helps machinists, setup operators, programmers, and small shop owners handle common lathe calculations faster, reduce manual math, copy reference values quickly, and review risk before running a job.

This is not a general-purpose calculator bundle. It is designed as a focused workspace for real turning scenarios, so users can go from input conditions to practical results with fewer taps.

Key features:

• G76 and G92 threading assistance
• Taper, arc, groove, chamfer, and coordinate calculations
• Conservative feeds and speeds recommendations for common turning operations
• Reference program skeletons for supported controller styles
• Pre-run risk checks and warning prompts
• Local machine profiles, material presets, and tool presets
• Saved history, reusable templates, favorites, and local backup import/export

Why users may find it useful:

• Works fully offline
• No login or account required
• Fast copyable results for machine-side use
• Designed around real lathe tasks instead of abstract formulas only
• Keeps frequently used inputs and references available locally

Important notice:

• All outputs are reference values and must be checked by the user
• Program output is a reference skeleton, not a finished production program
• The app does not connect to CNC machines
• The app does not send code to hardware
• The app does not control machine motion
