在铣削过程中获得良好的表面粗糙度对于减少塑料模具的生产时间非常重要。然而，关于五轴控制加工中心切削条件对表面粗糙度影响的研究还很少。本文在计算机模拟中考虑了球头铣刀的径向和轴向运动，包括加工中心的主轴轴线以及切削刃的轮廓。在实验中，还通过改变主轴轴线相对于工件表面的倾斜角度来进行实际铣削。模拟结果与实验结果吻合较好，在倾斜角度5°左右时获得最佳表面粗糙度。此外，还可以清楚地看出，精加工表面上存在多种图案，这些图案的生成对应于切削刃的角度位置和刀具相对于工作台位置的线性位置以及刀具的跳动之间的关系。
It is very important to get fine surface roughness in the milling process for reducing the production time of plastic molds. However, few research works on the effect of cutting conditions to the surface roughness have been conducted in the fiveaxis controlled machining centers. In this paper, both of the radial and axial motions of the ball-end mill including the spindle axis of the machining center are considered in the computer simulation as well as the profile of cutting edge. In the experiments, actual milling has been also done changing the tilting angle of the spindle axis relative to the surface of the workpiece. The simulated results have a good agreement with the experimental ones, and the best surface roughness is obtained at around 5 degrees of the tilting angle. In addition, it is made clear that there are several patterns on the finished surface and those patterns are generated corresponding to the relationship between the angle position of cutting edge and the linear position of tool relative to the table position as well as the run-out of the tool.
