Multi Objective Optimization Of Burnishing To Eliminate Heat Treatment In Reamer Shank Manufacturing By Using Taguchi Coupled Principal Component Analysis (PCA)

ABSTRACT

Burnishing is a well-known cold working technique for improving the surface integrity. It is cost-efficient and effective technique for enhancing surface finish as well as hardness. The use of burnishing to replace current heat treatment including grinding process on the reamer shank is offered as a unique strategy for reamer shank processing. This change in processing reduces cycle time and resources while also conserves energy required for processing during heat treatment and grinding. In this work, principal component analysis (PCA) is coupled with Taguchi optimisation technique to deal with multi-response problem to determine optimum parameter values of burnishing process to attain required surface finish and hardness in order to fulfill all functional requirements of shank. Test outcomes are convincing and show that suggested technique has ability to substitute current heat treatment along with grinding operation for reamer processing.
