Hello everyone,
Greetings and good day.
We have started using the minitab software, and we have taken a project in one of our manufacturing process “Crimping Operation“ to change the existing destructive testing method to attribute type non-destructive testing based on customer requirement
What is crimping operation ??
Crimping is the process of distorting the top thread of the nut, by using a tool with the necessary projections. This tool is fitted in a power press (or) special purpose machine (SPM).The load is directly applied on the thread / cone angle for distortion. The Schematic diagram is as given below:
In this process, after distortion, the physical changes are crimping depth and reduction in ID of the thread.
Expected outcome is the 1st installation, 1st removal and 5th installation torques which can be done only by destructive testing.
As a part of study, we have taken trials with 50 Nos. of samples from one of the subject part # and individual values are taken for:
Crimping diameter – Non destructive – variable measurement
Crimping depth – Non destructive – variable measurement
1st installation – Destructive – variable measurement
1st removal – Destructive – variable measuremen
5th removal – Destructive – variable measurement
Our idea, is to find out the relationship between the (Crimping ID & Crimping depth) to (1st installation, 1st removal and 5th removal)
Values are attached herewith for reference.
Initially I have conducted the normality test on all the 5 variable and found OK
Probability test OK
Pearson Correlation test conducted for each variables in tandom
Related minitab file with all datas attached herewith.
Pl.let me know if the above tests are sufficient enough to prove the relationship (or) is there any specific test to prove the relation.
It will be helpful, if you tell me the steps to follow.
Thanking you in advance.
