Elimination of Rough Milling and Grinding Machining Operation in Casting Bay Parts

摘要

This project involves the elimination of the rough machining and grinding operation by designing newer type of fixture for gear housing component (Vertical Machining Center). Various types of operations are involved in gear housing component. Some of them are rough milling, grinding, drilling, tapping, boring etc.. Here rough milling and grinding operation is pre-processed before it get machined in VMC center. In VMC (present method) three types of fixture are used to finish the gear housing component to required shape. With the help of newer type of fixture (proposed method) it not only eliminates the rough milling and grinding operation but also reduces the number of fixture into two. It automatically reduces the setup time and machining time. Newer type of the fixture is designed with the help of solid works software. As the rough machining and grinding operations are eliminated cycle time, fixture setup time, machining cost, man power will get reduced and productivity get increased.
