摘要
Abstract
The process of diamond tool cutting granite is essentially the process that a large number of diamond particles discretely distributed on the surface of diamond cutter complete the process of friction,plow and brittle cutting.To understand the complex cutting process,it is necessary to study the single particle cutting and the sequential cutting of particles,yet there are difficulties in conducting and analyzing the cutting experiment.In order to solve this problem,a numerical cutting model was built by using non-linear software LS-DYNA.The breaking and fracturing process of granite was analyzed by using its effective stress cloud diagram,from which the cutting force value was obtained.Besides,the influence of different cutting parameters on the cutting performance of single particle and particle in sequential cutting was studied.Cutting force of diamond particle could be accurately predicted,which provides references for selecting and designing diamond tools,improving the service life and processing quality of diamond tools,and selecting cutting parameters under different real working conditions.关键词
