Cutting Simulation with Force Feedback Device

Abstract

While calculation of reaction force in object cutting, we have to subdivide the original mesh of finite element method in the field where the stress concentration can be observed.
It causes a huge computational complexity. We constructed object cutting simulation system that is able to output reaction force to force feedback device using OpenGL library. The system consists of high speed deformation calculation using rough mesh, and static and dynamic calculation method of calculates reaction force to cutting tool.
