The FEM Analysis and Optimum Design of Elbow Link-Style CNC Punch

The FE analysis and calculation have been done through the finite element software COSMOS to the newly developed Elbow link-style CNC punching machine with researching in the deformation and the stress distribution of the body in the nominal pressure stroke and the influence of the structure towards the stress and the strain of the body.Optimized design of the body structure has been presented which can further reduces the weight of the body, the production cost,and raise its competition guaranteeing the rigidity of the machine based on the results.
