The CNC machine has eliminated an entire process for me. He added that he is able to use the additional time to run other tests and has been able to increase the lab's test capacity to more than twice what it handled before the CNC machine arrived. We could see major production increases coming and we had three alternatives. The engine must pass a leakage test that verifies assembly integrity. Cummins decided to focus on ensuring that one test station could adequately handle increased production.
Any leakage then causes the leaking cavity to lose pressure.
Any leakage between the cavities shows up as a pressure increase in the larger cavity. Two operators work i n tandem to conduct the test, one tending the water side and the other focusing on the air-oil side. Operators receive a green signal for a pass and red for a fail, similar to what the previous system provided. Cummins has reaped numerous benefits by using the InterTech Development testers. Faster fill and better stabilization, combined with the quicker response of the system's mass-flow technology, allowed the system to shorten our test cycle time to 40 seconds.
