CNC Quoter turns STEP files into rough machining estimates
A browser-based calculator reads a STEP file’s geometry and produces an itemized, ballpark CNC machining quote.
- For
- CNC shops preparing preliminary machining estimates
- Worth noticing
- Multi-solid assemblies can be quoted body by body or treated as a single part.
Field notes
The page accepts .step/.stp files up to 50 MB and displays geometry measures including bounding box, part volume, surface area, stock envelope, and estimated setups. Shop settings include material, quantity, hourly machine rate, stock allowance, setup and programming time, margin, and range width; the page says these settings are saved in browser localStorage. Multi-body files can be quoted body by body or as one part, while the site explicitly lists several machining factors its estimate does not account for.
