Before you release the project
- Define the function, environment and the question this batch must answer.
- Specify material grade, geometry, quantity, finish and the dimensions that control fit.
- Agree the inspection method and the evidence required to accept the parts.
- Record the drawing revision and approval before production begins.
Common planning questions
Which CNC process should I consider first?
Start with the geometry. Rotational parts are usually candidates for turning; pockets and planar faces suggest milling. Tool access, setups and hardened features decide whether multi-axis machining or EDM adds value.
Should every dimension have a tight tolerance?
Specify tight limits only where fit or function requires them, and define how those features will be measured. Broad tight-tolerance notes can add cost without improving the part.
What should accompany the CAD model?
Provide a controlled drawing, material grade, quantity, critical dimensions, finish and inspection requirements. Identify cosmetic and sealing surfaces before the quote.
Move from guidance to a reviewed project
Send the CAD model and drawing with material, quantity, finish and inspection requirements. Use the relevant service page to review the available manufacturing route.
