Abstract

In this work, Statistical process control (SPC) and Design of experiments (DOE) was used to reduce the cycle time of gear hobbing process. The roller lever shaft and gear shaft occupies about 35% production capacity of gear hobbing machine in a month. Statistical Process Control (SPC) analysis was done to identify how the process is performing against its specification limit. In order to increase the production without compromising the quality, the process parameters is should be enhanced to improve the quality. In this process, Hob tool, Feed rate, RPM and Hob material were considered as the most influencing input parameters. Cycle time was considered as a response variable. For experimentation Hob tool, Feed rate and RPM are used to found the best process parameter to get optimized cycle time. And finally it is observed that the feed rate is the dominating parameter to reduce the cycle time. The optimal parameter leads to decrease in processing time of gear hobbing in roller lever shaft by 26.29%.
