Precision machining does not begin until rough processing has been inspected.
Calipers, micrometers, and gauges are used by the inspectors to check dimensions. Machinists recheck vertical, inclined and shaped surfaces following machining. All semi-finished products are thoroughly checked in terms of size. These measures eliminate flaws and minimize the chances of rework.
Key checks include:
- Tightness and alignment of workpieces.
- Reference edge and positional size compliance.
- Size checking after rough machining.
- Check machining to draw accuracy.
3) Surface Finish Inspection
Product quality is directly related to surface quality and product functionality. Burrs and sharp edges are eliminated after machining. The visual inspection proves smoothness on all surfaces. Goods are tested on their roughness or scratches.
Measurement of surface roughness is done using precision instruments such as profilometers. Stricter checks are required on treated parts, including anodized or painted parts. Finishes on the surface are tested within established limits on the depth of coating and consistency.
Common checks include:
- Measurement of surface roughness.
- Burr and defect confirmation.
- Visual examination in controlled light.
- Coating thickness tolerance.
4) Other Inspection Tests
In addition to dimensional checks, special tests confirm mechanical properties and durability. Salt spray tests are used to test the resistance to corrosion of coated surfaces. Load-bearing strength of critical parts is verified by tensile tests. Hardness tests are used to measure the resistance of the material against deformation and wear.
