Abstract: In automobile industry gear manufacturing is highly important. To increase the production without sacrificing quality one of the most effective ways is by improving the substrate material hob. The influencing parameters for cutting process should be known and possible to control. Through the theoretical studies and experimental investigations of significant parameters such as feed, hob material, feed, surface finish, cost. A continuous process optimization is necessary to satisfy the customer demands. A basic approach in optimization of operation times, is changing the substrate material. Taguchi method can be used for selecting the design of experiments and suitable optimization method can be used to optimize the process. This research paper focuses on improving the productivity by using different cutter materials.

Keywords: Optimization, Taguchi, Gear hobbing, Productivity.
