Abstract

Cylindrical articles can be manufactured in a process wherein their dimensions are determined or measured with a gaging device. As shown in Figure 1, gaging device 1 is equipped with spindle 3, wheel 5, and handle 7 mounted on base 9. Gage spindles can be manufactured to rotational accuracies of 25 millionths or less. Typically, adaptors lla, llb, llc of various sizes are mounted on spindle 9 to fixture fabricated parts 19 for inspection. The adaptors are held in place with adaptor hold down screws 13 and centering/jacking screws 17 through centering collar 15. When adaptors are mounted onto the spindle as shown in Figure 1, it can be time consuming to locate, by means of mounting and centering with the jacking screws, the adaptors to replicate the inherent accuracy of the original spindles. Thus, the gage is normally utilized for measurement of production parts with inherent gaging errors of 100 to 400 millionths on each end, since an assembly is normally required on each end of the part. Accordingly, there are also gaging error measurements in the measurement data in addition to actual part variation measurements. Further, to mount the adaptor to the spindle results in an assembly with 2 or 3 pieces.
