Abstract
This paper presents the hybrid approach for optimization process of surface roughness in die sinking electric discharge machining (EDM) process. The optimization process is based on hybrid Harmony Search (HS) and Artificial Bee Colony (ABC). The data was collected from the experimental machining conducted using EDM AG40L. Harmony search (HS) algorithm is applied to optimize the surface roughness (Ra) performance of EDM process. However, HS was not sufficient enough to give better results to perform local search for numerical application in terms of fine-turning characteristic and convergence rate. Thus, hybrid HS-ABC is proposed to improve the weakness of the HS algorithm to get accurate optimal solution for EDM process. It was found that the optimal solution of the proposed HS-ABC has outperformed the result of single HS algorithm. � 2020 IEEE.
