Design and Manufacturing of In-Process Grinding Gauge

Abstract

The purpose of this project is to design and fabricate an in-process grinding gauge. This project is funded by Hybrid Engineering and will serve as proof of high-level capability of Hybrid Engineering. The gauge will be used to measure external diameter of the shaft which is being grinded by grinding wheel and once the shaft reaches the desired diameter then grinding process will be stopped. This gauge will help to make a grinding process an automated one. One LVDT probe is utilized to take the readings with an accuracy of 1 micron. The accuracy and precision requirements are specified by the Hybrid Engineering. The design of machine components is dictated by the dimensional constraints rather than stress and loading conditions since most components are stationary and have light in weight components to hold. The design is optimized to minimize the effect of friction on it. It is mainly due to innovative arrangement of carbon tips which will measure diameter of shaft and will make line contact with the shaft and thus will reduce the impact of friction. V-type shape is used so that it can get fit on the shaft and thus measure diameter of the shaft accurately.
