When you want to select the materials used in the production. Analysis of the transformation of material (Von Mises Stress) that the materials used in the design that can bear loading on the materials or not, by using the simulation method. And Modeling of the system of machine Chamfer by here will create a prototype made Chamfer to simulate production than the design so that it can be used. Can reduce the running time of the original work by people in work and increase work efficiency. The original can be produced per day, 2000 pieces per day into a working machine can produce up to 7 500 pieces per day. for work increased by 3.75 times from the original work itself
