1. Controlled manufacturing process
No part enters serial production without a documented and validated process route.
In practice
- Each part gets a process sheet: machining route, cutting parameters, tooling, and inspection plan
- New parts go through process validation on sample pieces before series production begins
- Machining parameters are documented and locked down, so repeat orders reproduce the same result
- Any material substitution or process change is justified and approved by the customer
Result
Consistent quality from the first part in a batch to the last, from the first order to the tenth.
