- Castings will normally meet MIL 2175 Grade B or C dependent on wall thickness and variation in sections.
- Leak testing can be carried out as necessary.
- Dye penetrant testing is carried out to BS M39 or ASNT level 2.
- Fully automatic co-ordinate measuring machine (CMM) with statistical process control (SPC) software.
- Mechanical/destructive testing carried out to suit your requirements.
Inspection criteria :
- Specify co-ordinate systems where necessary (see Appendix: Datum systems).
- Ensure that critical dimensions are agreed prior to tooling manufacture. Keep these dimensions to a minimum, preferably no more than five.
- Agree control measurements for production.
- Agree touch points for machining and co-ordinate measuring machine.
Relaxing tolerances in some areas may allow others to be tightened.
