Classification of robots according to the motion trajectory of CNC lathes(2)

When processing, it is necessary to control not only the starting point and the end point, but also the speed and position of each point in the entire processing process, so that the CNC lathe robot can process parts with complex shapes according to the drawings. Its auxiliary functions are also relatively complete.

　　CNC processing is classified by numerical control device

cnc processing

　　(1) Hard-line CNC lathe robot processing (commonly known as ordinary CNC, namely NC). The input, interpolation and control functions of this numerical control system are realized by integrated circuits or discrete components.

　　 Generally speaking, CNC lathe robots are different, and their control circuits are also different, so the versatility of the system is poor, because it is all composed of hardware, so the functions and flexibility are also poor. This system was widely used before the 1970s.

　　 (2) Flexible wire numerical control lathe robot processing (also known as computer numerical control or microcomputer numerical control, namely CNC or MNC). This system uses medium, large-scale and very large-scale integrated circuits to form numerical control equipment, or uses a microcomputer and special integrated chips. Its main numerical control functions are almost completely realized by software. For different CNC lathe robots, only need to compile different Software implementation, and hardware are almost universal.

　　Therefore, it has flexibility and adaptability, and is easy for mass production. The software and hardware are modularized, which improves the quality and reliability of the system. Therefore, modern CNC lathe robots all use CNC devices.

　　Cnc processing is classified by process usage

　　 (1) Ordinary CNC lathe robot processing. Compared with the traditional ordinary lathe processing, this kind of CNC lathe robot processing has CNC turning, milling, boring, drilling, grinder and other machining methods. The possibility of this CNC lathe robot processing technology is similar to that of ordinary machine tools, but the difference is It can process parts with complex shapes.

　　(2) CNC lathe robot processing. This CNC lathe robot processing is developed on the basis of ordinary CNC lathe robot processing.

In the ordinary CNC lathe robot is equipped with a tool magazine (which can accommodate 10-100), the equipment composed of tools and automatic tool equipment uses automatic tools to change the CNC lathe robot (also called multi-step or boring and milling machining center, the CNC lathe robot is usually called For machining centers), the development direction of CNC lathe robot processing is further automated and efficient.

　　(3) Multi-coordinate CNC lathe robot processing. Some parts with complex shapes cannot be processed by robots with three-coordinate CNC lathes, such as the processing of propellers and aircraft surface parts, which require a comprehensive movement of more than three coordinates to process the desired shape.

　　 Then appeared a multi-coordinate CNC lathe robot to process the robot, which is characterized by a large number of CNC equipment control axes and a complex lathe structure. The number of coordinate axes usually depends on the processing requirements of the processed parts.
