Hi, I love this powerful impact video demo. I always wanted to redesign an auto part to any vehicle.. but don't no how to go about it. its a redesign of a GAS LINE with better flow of gas wear in we do have go to the gas station for about a 30 day or more. its just my idear.

When I was in Jr. High, often the teachers would tell you that you could correct your own test. Whenever I got the chance to correct my own test I ALWAYS got an A. This is the issue with inspection on the machine that cut the part. Any of the errors in the setup of the machine will be masked in the inspection. If the Axis are not square the measurements will be made and not reveal that error in the part - the measurement tool is out of alignment an equal value as the tool that produced the geometry. Any other machine misalignment will be masked as well. Checking the part with a probe on the machine that has the same error will not provide you with a true quality check of the part. You will always get an A. There are ways around this. By checking the part to and from a standard that is independent of the machine, it will take only simple calculations to determine dimensions. Caveat Emptor!
Hi Mike, you raise valid points. On-machine verification (OMV) does not replace traditional inspection routines using co-ordinate measuring machines (CMMs) - it complements them.
OMV helps manufacturers and CNC machinists in a number of ways.
1) It helps with part setup - particularly useful when working with stock material that is either large/heavy or of an unusual shape (making it hard to “clock” parts into a known datum position).
2) It can help identify gross manufacturing errors during the machining process and avoid having to transfer the part from the CNC machine tool to the inspection department. Probing the part on the machine allows issues to be found and steps to be taken to avoid the problem snowballing into something that could be far more costly to resolve.
3) For the most demanding of manufacturing facilities, OMV can even be used to check the kinematic accuracy of the CNC machine tool itself (e.g. checking for, and correcting, any inaccuracy found in the rotary axes).
Hopefully this helps explain OMV a bit more. If you have further questions please feel free to contact us 1 855 612 9998.
