CNC machining time calculator
Machining Time
From drawing to a real time estimate in minutes. Upload the drawing, the app recognizes holes, threads and contours, and calculates machining time using your actual tools, materials and machines.
Features
AI drawing recognition
Upload a PDF drawing and AI automatically recognizes holes, threads, contours and material — ready for the calculator, with manual correction available.
Machining time calculator
Drilling, contour milling, roughing and tapping — each operation by its own formula, plus setup, tool changes and buffer.
Tool library
Your actual tools with diameters and cutting parameters per material — auto-suggested when you pick a tool for an operation.
Machines and materials
Manage your list of machines and materials with aliases (e.g. S355, S355J2) so they find the right cutting parameters automatically.
Job history
Every saved part keeps its drawing, data and calculated time — reopen it instead of calculating from scratch.
How it works
- 1 Upload the part's drawing (PDF) — AI recognizes holes, threads and contours automatically.
- 2 Review and correct what was recognized, pick a machine and material from your lists.
- 3 The calculator computes machining time per operation — setup, tool changes and buffer included.
- 4 Save the part to your history — reopen it instead of calculating from scratch.

Drawing privacy
Uploaded drawings stay private to you — they're not publicly accessible and aren't visible to other users.
AI recognition is optional: you can enter the data manually without the drawing ever being sent for automatic analysis.
When AI recognition is used, the drawing is processed through Anthropic's (Claude) API — by default it isn't used to train models and is automatically deleted within 30 days.
