To correctly operate CNC machine tools, to avoid problems caused by improper operation, we need to understand and master the composition of CNC machine tools and work steps, the next I will introduce you to the composition of CNC machine tools and work steps:.
CNC machine tools consist of four components: CNC unit, servo system, position feedback system, and mechanical parts of the machine pair. Here we understand the four components one by one.
CNC unit is the core of CNC machine tools, by the information input, processing and output of three parts. CNC unit to accept digital information, after the CNC control software and logic circuit for decoding, interpolation, logic processing, will be a variety of instruction information output to the servo system, the servo system to drive the implementation of the parts for the feed motion.
Second, the servo system. By the driver, drive motor, and with the machine tool on the implementation of the components and mechanical drive components of the CNC machine feed system. Its role is to convert the pulse signal from the CNC device into the movement of the moving parts of the machine tool.
Third, the position feedback system. Servo motor feedback of the angular displacement, CNC machine tool actuator (table) displacement feedback. Including grating, rotary encoder, laser rangefinder, magnetic scale, etc.
Fourth, the mechanical components of the machine tool. CNC machine tool mechanical components are similar to the composition of ordinary machine tools, but the transmission structure requirements are more simple, in terms of accuracy, rigidity, seismic requirements, and its transmission and speed change system is more convenient to achieve automated expansion.
CNC machine tool work steps: divided into the preparation stage and programming stage
Preparation stage: According to the drawing of the processed part, determine the relevant processing data, and select the relevant other auxiliary information according to the processing process, tool type, etc.
Programming phase: according to the machining process information, write the CNC machining program and fill in the program sheet.
