Testing critical functions
The situation: we’re in a production line operation. The job here is to test large unit numbers. Often even the entire production run is tested. Using manufacturing and assembly test benches, also known as production test benches when combined together, tests are run on just the key features and functions. Product testing in done on a spot-check basis. The aim is fast testing routines.
As the speed increases, so too does the strain on the machines. And thus the table turns: while laboratory test benches test only a few samples, albeit however in minute detail, manufacturing test benches are on their behalf themselves subjected to a permanent endurance test.
The machines decides between Yes and No
Testing high unit numbers requires automation. And automation wouldn’t be automation if the machines didn’t take over some of the human’s key tasks. Autonomous work is called for. Test benches in manufacturing and assembly require an expert system other than a human being. The machine decides between good and bad. For it to be able to do this complex control systems and programme applications are required.
A little theory of evolution - The development of a production test bench
- Step 1: The development test bench is built
- Step 2: Findings from this are incorporated into the construction of the production test bench
- Step 3: The production test bench is given trimmed-down functionality
- Step 4: Its stability is enhanced
- Step 5: The complexity of the degree of automation increases
