The material efficiency test was also partly compromised in the first run since there were 7 scrapped parts. There was a 12% yield of the material for the first test. The second test resulted in 16% yield of material. The increase is due ultimately to the less scrap parts. This is an improvement over the current method's 10.7% yield of material.
As mentioned before, the first test is the least representative of what a production set up would be like. In reality, the kinks of the process would be worked out. That is what is representative in the second test. There was an improvement as the process was corrected and practiced, however, in an actual production setting, 3 scrap parts out of 24 total is unacceptable. Scrap parts should occur far less often.
​
Overall the project was successful. Comparing the results of this tests to the current method for producing the bottle openers, every metric was exceeded.
The first time test was flawed due to settings on the CNC mill, which resulted in 7 scrapped parts and thus resulted in 9.4 minutes per part.
​
The second test produced only 3 scrapped parts, and ultimately reduced the time per parts to 7.1 minutes per part. This is more accurate and reliable since there was a smooth process going on for this test.
