摘要
主要采用有限元软件对金刚石空心磨头磨削工程陶瓷过程中金刚石空心磨头的结构破坏分析,对刀具强度和刚度影响较为显著的壁厚和外径进行仿真,结果表明随着刀具壁厚的增加,刀具整体受到的等效应力明显减小,刀具外径增大的同时磨削力增大,材料去除率增大且刀具较易破坏,最终找出磨削工程陶瓷合理的刀具结构参数。最后利用金刚石空心磨头对工程陶瓷进行加工,金刚石空心磨头未发生破坏。
This paper mainly studies about the cause of diamond hollow grinding structural failure when diamond hollow grindingis milling engineering ceramics by finite element software,and this paper is proceed from some factors of considerably affect to strength and rigidity of diamond hollow grinding to analyse external diameter and cutter thickness by finite element software simulation.The results show that the increase in cutter thickness as the cutting tool,the whole of cutting tool is forced the equivalent stress decreased significantly,while increasing the tool diameter result to increase grinding force,material removal rate is larger and damage the tool easier.At last this paper finds a reasonable milling tool structural parameters to mill engineering ceramics.Finally,using the diamond hollow grinding for experimental processing to grind engineering ceramics,diamond cutter doesn＇t be damaged.
