Metal cutting is used to remove excess metal from the surface of the workpiece with a tool to obtain the desired shape and size of the workpiece. The essence of the cutting process is that the workpiece cutting layer produces plastic deformation under the extrusion of the front edge of the cutter, and becomes a complicated process of cutting.
In the process of many physical phenomena such as cutting force, cutting heat, tool wear and tool life, chip curling and the chip-breaking, etc., have close relationship with the deformation of the metal, will affect the machining quality, productivity and production cost. In actual production, PURROS think, need to know the basic principles of metal cutting, need to grasp the regularity of deformation process of metal cutting, active processing control effectively, so as to create more advanced processing methods and efficient cutting tools.
