Metal cutting is a material removal and forming method in metal forming process, and it still accounts for a large proportion in today’s mechanical manufacturing.
The metal cutting process is a process of interaction between the workpiece and the tool. The tool removes excess metal from the workpiece to be processed, and under the premise of controlling productivity and cost, the workpiece is made to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements.
To achieve this process, there must be relative motion between the workpiece and the tool, that is, cutting motion, which is provided by the metal cutting machine tool. The machine tool, fixture, tool and workpiece constitute a mechanical processing system.
Various phenomena and laws of the metal cutting process will be studied in the motion state of this system.
