FEM Simulation of NC Machining Processes Objectives To predict the effects of insitu residual stress redistribution due to complex 3D machining of bulk components. To streamline process design so as to minimize part fit-up issues. Bottomline : To reduce manufacturing cycle time thereby achieving productivity improvement and cost savings. FEM Simulation of NC Machining Processes Approach Pseudo-simulation of machining process through automated material removal using NC cutting files (apt or cl files) as input. Assumption Apriori residual stresses in depth of work-piece influence resulting distortions more than surface residual stresses introduced by cutting process.
