So, I am using a romer arm to measure concentricity of two holes. With a traditional CMM (and different software) we have found the concentricity of the holes to be 0.26mm. However, with the romer arm it shows the concentricity to be 2.9mm. If you take the acuals from the two holes and calculate the concentricity it should read like the traditional CMM???? Why is PC DMIS not giving me the correct reading? Any suggestions on how to measure this dimension with the Romer ARM?
As for the cost of the equipment.... that thing is a MANUAL machine. You must control it, it will not do it for you, and all it takes is a little slop on the part of the operator and all the data is bogus.
