DR. MOHD RIDHA MUHAMAD
Ridha is a Senior Lecturer in the Department of Mechanical Engineering and is jointly an associate member of Advanced Manufacturing and Materials Processing (AMMP) Center at the University of Malaya. He obtained Doctor of Engineering from Utsunomiya University Japan in 2015, specializing in magnetic abrasive finishing for finishing of tube internal surface. Prior to his doctoral study, he worked in Yamazaki Mazak Corporation as a Senior Mechanical Design Engineer focusing on CNC prototype machine design and evaluations for mass production. He performed more than 100 types of lathe cutting conditions such as OD and ID cutting, ID boring, intermittent cutting, roundness cutting using diamond tool, etc to confirm the machine limits and capabilities. Currently, he is working on magnetic manufacturing method for various applications in heat exchangers and surface finishing. In a separate project, he is collaborating with Joining Welding Research Institute (JWRI), Osaka University Japan to optimize friction stir welding process in a sustainable way to be implemented in manufacturing industry in Malaysia. The project explores the possibilities of joining similar and dissimilar materials such as polycarbonate/aluminium, aluminium/stainless steel, magnesium/steel, aluminium/copper for various applications in automotive industry. In managing the current pandemic, he tries to develop mask sterilizer machine to disinfect N95 for reusage and design & developing an aerosol collector during dental treatment for infection prevention.
