Abstract

To furthermore optimize the machining parameters and improve the surface quality of the workpieces manufactured by single point incremental forming method, the formation mechanism of the sacle veins on the metal incremental froming workpieces was studied through experiment method. The influence principle of the spindle speed, the feed speed and the material of tip of tools on the length of scale veins was obtained through analyzing the experimental results and building the mathematical model among the length of scale veins, feed speed and spindle speed through measuring the roughness of surfaces and observing the appearance of the forming workpieces. The experimental results showed that, the spindle speed, the feed speed and the material of tool tips have a significant effect on the scale veins formation on the surface of forming workpieces. Therefore, an appropriate group of spindle speed and feed speed can reduce the effect of scale veins on the roughness of single point incremental forming workpieces and furthermore improve the surface quality of forming workpieces.

单点增量成形工件表面“皮纹”的影响因素研究

为了进一步优化单点增量成形加工工艺参数，提高单点增量成形工件的表面质量，通过实验方法研究了金属增量成形工件上锯齿纹的形成机理。通过对实验结果的分析，得出了主轴转速、进给速度和刀尖材料对鳞纹长度的影响规律，并通过对表面粗糙度的测量和对成形工件外观的观察，建立了鳞纹长度、进给速度和主轴转速之间的数学模型。实验结果表明，主轴转速、进给速度和刀尖材料对成形工件表面水垢纹的形成有显著影响。因此，选择合适的主轴转速和进给速度组，可以减小水垢纹对单点增量成形工件粗糙度的影响，进而提高成形工件的表面质量。
