摘 要: 建立了切削过程三维温度及热应力模型,整体模拟了金属的切削过程,得到不同切削速度下的切削力,工件变形区的应变、应力分布以及切削温度的分布,并对切削速度以及刀具前角对切削温度分布的影响进行分析。结果表明,提高切削速度对于减小主切削力,降低切削温度是有利的。三维仿真能更加真实地揭示刀具和工件的切削状态。 The establishment of the cutting process three-dimensional model of temperature and thermal stress ,the overall simulation of the metal cutting process ,have different cutting speed of cutting force ,part of the contingency deformation zone ,cutting the stress distribution and the distribution of temperature and knives before cutting speed and angle Cutting the temperature distribution in the analysis. The results showed that the increase cutting speed for the main cutting force reduction,lower cutting temperature is favorable. 3D simulation can be more truly reveals the cutting tool and the workpiece state.
