Abstract
The dimensional accuracy of built-in parallel rollers is generally considered a significant factor affecting the movement accuracy of high-precision machining tools. A previous report based on the V-block method examines dimensional distortion of 1200 parallel rollers to obtain it's effect on movement accuracy of machining tools equipped with these rollers. Yet, these results are based on roundness measurements of a single cross-section, and thus lack preciseness in illustrating the complete dimensional profile of the rollers. Thus in this report, we introduce a newly developed method enabling mearurement of simplified cylindricity. The roller was supported at two points by two independent V-blocks, while measurements were simultaneously taken at three points ; namely the two cross-sections supported by the V-blocks and a third cross-section. These results were combined to provide the cylindricity of the measured roller. Furthermore, 200 parallel rollers of a uniform standard were measured to analyze the distribution of radius, roundness, and cylindricity.
