Research On High-speed Cnc Engraving And Milling Machine

High-speed CNC engraving and milling machine is a high-tech equipment in which CAD/CAM, image processing, HSM, CNC, precision mechanical design and manufacture, engraving and milling technology, motor driver technology and build-in motor spindle technology are integrated. The main purpose of this dissertation is to research and develop high-speed CNC engraving and milling machine.At first, this dissertation introduces the basic technology of high-speed CNC engraving and milling machine, such as CNC technology, engraving and milling technology and ultra-high speed machining technology. Then, from the viewpoint of characteristic, structure, performance and application, high-speed CNC engraving and milling machine is discussed in detail; furthermore the information of the similar one is also mentioned in home and abroad.The key of the paper is in chapter 3 to chapter 6, in which, control system, system software and CAD/CAM integrative automatic programming software are studied detailedly.The constitution of control system of high-speed CNC engraving and milling machine is analyzed in chapter 3, given emphasis to motion controller, spindle driver and feed driver.System software is designed and programmed in chapter 4, including the analyses and researches on software structure, module of vital manage, module of tool compensation and module of interpolation.The design of CAD/CAM integrative automatic programming software is made in chapter 5. The development of computer aided programming system is introduced, as well as the function analysis is performed. In addition, CAD/CAM integrative automatic programming software is developed in the 2-D graphics and image processing filed.The test of high-speed CNC engraving and milling machine has been carried out and running examples are exhibited in Chapter 6.Finally, the research contents of this dissertation have been summarized and the prospect of engraving and milling machine has been opened up.
