高速铣削钛合金Ti-6Al-4V切削力仿真研究

切削力对工件的机械加工性和刀具磨损有重要的影响。基于有限元仿真技术,针对钛合金Ti-6Al-4V高速铣削力进行数值仿真,重点研究切削参数对铣削力的影响规律。结果表明:随着每齿进给量和径向切深的增加,切削力有不同程度的增加;随着轴向切深的增加,切削力呈正比增加趋势,但主轴转速对铣削力影响并不明显。分析结果为钛合金Ti-6Al-4V高速铣削加工工艺参数优化奠定了基础。

Simulation Research on Cutting Force in High Speed Milling of Ti-6Al-4V

The cutting force of titanium alloy Ti-6A1-4V was simulated by FEM. Cutting force was taken into account due to its predominant roles to determine machinability and tool wear during machining of Ti-6A1-4V. It was focused to study the effects of Cutting Parameters on the cutting force. Results of the study show that the cutting force increase in def： erent degree with the increase of feed per tooth and radial cutting depth, while cutting speed doesn＇ t have obvious influ- ence on the cutting force; The cutting force increases in direct ratio with axial cutting depth. This work will be a＂ base for process parameter, optimization
