Measuring Instruments
Not only in today's machine shops have the machine tools advanced in technology and ease of use but the measuring instruments and inspection machines have also kept pace. They now have equipment in the inspection departments of some shops that you can virtually take a finished part and lay it on the table of this inspection machine. With a scope that is built on the machine it looks at the part and tells you after pushing a few buttons the dimensions of that certain part and whether or not it meets it's specifications. From start to finish the whole process is completed in a matter of minutes. It wasn't all that long ago when the inspection machines had to be programmed to the finish specifications of the part and the part had to be setup on the machine and then a stylus went around the part and touched it in certain places to take measurement readings. This process from the start of programming to complete checking the part could take hours. Just another example of how fast technology is propelling us into the future.

Technology is great as long as someone checks the cordax and understand that manual checks performed should come very close to the machine. Problem at the shop i work at is the machine is always right. What if someone bumped it? Or if dirt got into the part. And if it averages the bores and turns then the part can show correct but acutally be out of tolerance. I believe it takes more than a machine alone to measure parts we still have to manually check and recheck ourselves. But yes machines are more accurate in a controled environmnet and faster.
