Research Overview

• Advanced Manufacturing Processes
  
  Our research activities are primarily focused on modeling of various manufacturing processes viz. laser bending; laser micro-machining; thin-wall machining; single point diamond turning. Physics based models are being developed using analytical as well as numerical techniques (FEM). Moreover we also carry out experimental study on these processes. Our objective is to understand the physics of the processes using numerical modeling and to develop accurate predictive models which will help to improve the productivity of the process.
