Quality Control: Marking, Straightening, and CMM Measurement

that's why we don't have 16 verticos anymore this is the fun stuff right here you know this this probably is my favorite room the two my two favorite rooms in comp camps would be the test sales we have in the back in our quality room and when i first started at comp in 1995 i wanted cnc grinders and i want them so bad i could taste them i tried everything in the world to get my boss scooter brothers to buy a couple of cnc grinders and it really wasn't going well and so what happened is eventually he just took me aside he said billy you want to make ball bearings you want to measure them with the wood calipers and he said something that was probably one of the most influential things i've ever been told he said billy you can't make something better than you can measure it and that led to basically this room in here in 1998 he and i flew to marlborough massachusetts to meet with the addison cole corporation and we sat down and talked to them about what they have been just making is the state of the art rotary cmm's for camshafts and you can see our first one over here so we bought this unit in 1998 so this this camshaft was measured on it um you can see it has the degree head down here has got two high and high and diffraction grading encoders on it on about a 12 inch head this can measure an angle down way way not to the millionths but not even to the trillions but actually further than that into a degree actually calculated one time it's a wavelength of light on 12 inches time two because you have opposite encoders on it you have the same height and height encoders on the probe that goes out and measures the camshaft so we had these before we had the cnc grinders and it works very much the same way you know when the guys when the when the cam comes into qc after it's been grounded the operator goes in here and he puts in the information about camshafts types of serial number and it will tell them everything about the camshaft then they take that and they go over to them to the ag hole and they input what's the core number and what's the sequence when they start the routine to ask it what's the intake design id what's exhaust id what's the load separation advance it then creates a temporary part data file and it measures the camshaft 3.3 cuts a load to a quarter or a tenth of degree depending on the machine so either 1440 points or 3600 points on all three cuts on every load [Music] and it compares that to actually the design so whatever whatever chris…
