CNC Machining Tolerances and Specifications
Final capability depends on material, part size, geometry, feature depth, wall thickness, tool access, fixturing, surface finish, production quantity, and inspection method.
| Requirement | Typical Approach | Buyer Guidance |
|---|---|---|
| General Dimensions | Manufactured to drawing or agreed general tolerance | Mark functional and assembly dimensions separately |
| Tight Tolerances | Reviewed according to geometry, size, material, and feature location | Apply tight tolerances only where functionally necessary |
| Positional Accuracy | Controlled through datum, setup, and inspection planning | Clearly define datums and GD&T requirements |
| Surface Roughness | Machined finish or specified roughness after process review | Identify sealing, sliding, bearing, and cosmetic surfaces |
| Deep Features | Evaluated based on tool access, depth, width, and material | Avoid unnecessary deep and narrow cavities where possible |
| Inspection | First-piece, in-process, visual, and final dimensional checks | State required reports and documentation before quotation |
