Compare with the sophisticated equipment overseas, the domestic enterprise especially many Small and medium-sized ones the V-ribbed belt milling machine already appears backward in the production method and the production efficiency, so its hard to guarantee the size and the precision of the V-ribbed belt at present. Because its expensive to import foreign equipments, a lot of money will be saved if enterprises can make a qualified V-ribbed belt milling machine's thenselves, Thus it can be seen, develop a V-ribbed belt milling machine with complete function and low cost, will have a very bright future This article mainly introduces the designing of V-ribbed belt milling machine control system which used PLC as the main part, and the choicing of the main parts of the control system according to the request. After reading a many literature of science and technology and analyzing the foundation of both the domestic and foreign equipment, a design of the control system has come out. This V-ribbed belt milling machine control system is made up mainly by FX2N-32MR (main module), FX2N-1PG-E (high speed pulse module) and the step-by-step electrical machinery driver and so on. a part of software's design has be done too,and some of the program has been made up.
