Paul W. Critchley saw the power of lean as a plant manager at a growing medical device company. As the orders increased, every day the two-person shipping department struggled to make deadlines, getting in at 6:30 a.m. and rushing all day in order to make the UPS truck deadline at 5 p.m.
For more than 50 years, coordinate measuring machines (CMMs) have been improving measurement productivity and quality. The power of CMMs has made many complex inspection tasks seem almost trivial. With this much measurement capability, is it possible operators are taking their CMMs for granted?
In conventional 3D scanning measurement methods the CMM performs all the movements necessary to acquire the surface data. Acceleration forces induce inertia deflections into the CMM 3d scanning frame structure, which in turn induce measurement errors.
