CONTROL OF CUTTER MARKS ARRAY BY SIMULTANEOUS MULTI-AXIS CONTROLLED MILLING USING BALL-END MILL

摘要本研究旨在探讨球头铣刀多轴联动控制铣削所产生的刀痕阵列。我们提出了一种分析方法，使用球面近似的刀痕。实验结果与刀痕球面近似的解析结果吻合较好。其次，圆柱形表面加工沿着螺旋刀具路径的同时多轴控制铣削。结果表明，三轴联动控制铣削加工中，进给方向上的刀痕宽度可以通过旋转轴和平移轴的合成速度来控制。然后，介绍了应用分片铣削技术加工球面的实验结果。结果表明，对于任意三角形曲面片，通过适当设置每齿进给量和横向进给量，可以控制刀痕阵列相对于进给方向的倾斜角。

The purpose of this study is to control the cutter marks array generated with simultaneous multi-axis controlled milling by using ball-end mill. We propose an analysis method that uses spherical approximation of cutter marks. The experimental results agree well with the analytic results of the spherical approximation of cutter marks. Next, a cylindrical surface was machined along a spiral tool path by simultaneous multi-axis controlled milling. It was found that the cutter mark width in feed direction to the simultaneous 3-axis controlled milling can be controlled by using composition velocity of rotary and translational axes. And then, the experimental results of applying a patch division milling technique to a spherical surface are described. It is shown that the inclination angle of cutter marks array against the feed direction can be controlled by the appropriate setting of feed per tooth and cross feed for an arbitrary triangle patch.
