Simulation Research on Topological Grinding on Structured Surface of Guide Rail
In order to grind out the structured surface of the sliding guide rail of the machine tool,according to the technical re-quirements of the sliding guide rail scraping surface,three kinds of guide rail patterns of square,diamond and crescent were proposed.According to the limit of the number of high points and the area proportion on the surface of 25 mm×25 mm guide rail,the structured surface of the machine tool sliding guide rail was designed.According to the formation conditions of the structured surface of the grinding guide,the topological mapping matrix between the structured surface and the structured wheel was established,and the corresponding structured wheel was designed.The influence law of grinding parameters on surface morphology was obtained by MATLAB grinding kine-matics simulation.The results show that the topological grinding method can be used to grind the structured surface of the workpiece that meets the requirements of the guide rail surface by selecting the parameters of wheel speed,workpiece feed speed and grinding depth reasonably;with the increase of grinding depth,the length and width of the guide rail pattern increase,and the area ratio of the high point decreases.
