Seminar on basic knowledge and operation of CNC machine tools

Various types of CNC machines have two or more axes of motion. All metal cutting machines require their axes of motion to be accurately positioned within their respective motion intervals. Compared with ordinary machine tools, the superiority of CNC machine tools is first manifested in the automatic, precise and continuous smooth motion control functions of CNC machine tools. 1. Motion form and its control Generally speaking, the CNC machine tool motion control function has the following items: 1 Motion form control. 2 motion axis and motion direction control. 3 movement amount and movement rate control. The most common forms of motion for machine tools are linear motion and circular motion. There are three types of motion of CNC machine tools. In addition to linear and circular cutting motion, there is also a kind of "Rapid Travel", which is used for
