The closer you move quality measurement and inspection to the place where the work is being done, the sooner you'll know when something goes wrong. You'll catch it, you'll correct it, and you'll continue to make workpieces that meet all of the customer's requirements. And let the customer know you've moved your quality control to the work station and how that step benefits them. It's a plus, especially when seeking contracts from global companies. Fact is, some large companies won't even consider you as a supplier if you haven't taken this step.
Some shops have a mind set about quality assurance.
They still think of it as the last step before parts are shipped. By then, it's too late. You've lost the time, and you've lost the work. Besides, your customer doesn't even want to think about a part that's out of spec getting past your quality assurance procedures and in his door. The good news is if your shop has a personal computer, you are already halfway to moving measurement to the shop floor.
