Take 10. No. of components from the batch for inspection by eddy current testing machine (ECT).
2- Ensure that the material of the parts, heat wise tested is ok.
3- Adjust the ECT as per material, with respect to the following-
- Material checking after Pre- machining
- All 10 no. are from one heat
- Material checking is done heat wise
4-Ensure that the sine curve generated by the master rejection sample show distinctly sine wave curve in comparison with 10 ok parts checked by the master sample.
5- Take trial with ok and not ok (out of tolerance) parts to see the behavior of sine wave curves.
6- If the results are ok give the clearance to the operators for segregation of the lot in ECT machine.
