Project Background
The client is an automation equipment manufacturer (name withheld under NDA).
Scope: precision motion components used in an automated machine.
- Material: 7075-T6 aluminum
- Process: CNC machining
- Part characteristics: long dimensions, high precision requirements
Key challenges:
- Long parts tend to deform during cutting;
- Tight flatness on mounting faces;
- Stable batch supply required.
Key Requirements
Primary control items:
- Length dimensions;
- Flatness of mounting faces;
- Hole position accuracy;
- Surface treatment consistency.
Technical requirements:
- Dimensional tolerance: ±0.05 mm
- Mounting-face flatness: 0.03 mm
- Stable dimensions after anodising.
Process
Drawing Analysis
Based on the geometry:
- Stock allowance reviewed;
- Deformation risk assessed;
- Machining route optimised.
Process Optimisation
Setup:
- Multi-stage machining;
- Stress-relief control;
- Finishing pass for final dimensions.
First-Article Validation
Workflow:
- First article produced;
- Full-dimensional inspection;
- Series production released after sign-off.
Quality Control
Includes:
- In-process patrol inspection;
- Recording of critical dimensions;
- Pre-shipment inspection.
Verifiable Documentation
- Part photographs;
- Inspection report;
- Material certificate;
- Shipping documents.
Outcome
- Client validation completed;
- Delivery met project requirements;
- Subsequent orders supported.
