| 中文摘要: |
| 本文基于ABAQUS软件的Johnson-Cook材料模型以及ALE网格划分技术对钛合金稳态切削加工过程进行了有限元模拟，并研究了钛合金的切屑成型过程、切削层的塑形应变以及工件温度的分布，从切屑形状上看，模拟结果与试验结果基本吻合。在此基础上分析了不同切削前角、切削深度和切削速度等参数对切削力的影响，发现在一定范围内适当增大切削前角或减小切削深度有利于切削的进行，此外切削速度的变化在一定范围内对切削力影响较小。 |
| 英文摘要: |
| The titanium alloy steady cutting process was simulated and analyzed by Johnson-cook material constitutive model and ALE meshing technology based on ABAQUS. The chip forming, the distribution of plastic strain in the cutting layer, and the temperature distribution of work-piece in the cutting process have been studied. The simulation results are in agreement with the experimental results from the chip shape. Then the influences that different parameters (tool rake angle, cutting depth and cutting speed) have on cutting force have been discussed. It has beens found that in a certain range, increase of cutting angle or decrease cutting depth is good for cutting. Besides, the change of cutting speed only has a little effect on the cutting force in a certain range. |
