The numerical control equipment in the 21st century will be an intelligent system. The contents of intellectualization include all aspects in the CNC system: in order to pursue the intellectualization of machining efficiency and quality, such as adaptive control of machining process, automatic generation of process parameters; In order to improve the drive performance and use the intelligence of connection, such as feedforward control, adaptive calculation of motor parameters, automatic identification of load, automatic selection of model, self-tuning, etc.

The common lathe has a wide range of machining objects, a wide range of spindle speed and feed adjustment, and can process the internal and external surfaces, end faces, and internal and external threads of workpieces. This kind of lathe is mainly manually operated by workers, with low production efficiency, and is suitable for single piece, small batch production and repair workshops.
