The study deals with a new machining concept by making use of 6-axis control. 6-axis control implies that a cutting tool allows three rotational movements for positioning as well as three translational ones. A 6-axis control machining center equipped with a main spindle capable of tool orientation in addition to conventional 5-axis control structure is developed. A non-rotational cutting tool is mounted at the main spindle to carry out 6-axis contorl machining, which allows a variety of machining possibilities. Namely, 6-axis control machining with a non-rotational cutting tool can show the potential of new machining technology. Two kinds of new machining technologies are investigated in the study.At first, a control software to finish workpieces with sculptured surface in the coarse pickfeed is presented together with cuting experiments. As a result, it is found that 6-axis control machining reveals the possibility of finishing with good surface roughness.Secondly, the study deals with the development of a software system for asymmetrical grooving on a sculptured surface by use of a non-rotational cutting tool. The shape of the tool is the same as the cross section of the groove. Asymmetrical grooving, which is improssible to machine with 3-to 5-axis control, is one of the characteristic features of 6-axis control machining. The system consists of two stages : the first is to define a groove path and a groove shape with an asymmetrical cross section, the second is to paste the groove path together on the workpiece surface and to generate CL data corresponding to the groove shape, taking account of overcutting and collisions. Generated CL data are then converted to NC data for a 6-axis control machining center by the postprocessor. This software system shows the validity of 6-axis asymmetrical grooving.

该研究利用 6 轴控制来探讨新的加工概念。 6 轴控制意味着切削刀具允许三个旋转运动用于定位以及三个平移运动。开发出除了传统的5轴控制结构外还配备了能够刀具定向的主轴的6轴控制加工中心。主轴上安装非旋转刀具，进行六轴控制加工，实现多种加工可能性。即，使用非旋转刀具的六轴控制加工可以显示新加工技术的潜力。本研究研究了两种新型加工技术。首先，结合切削实验，提出了一种粗进给精加工雕刻表面工件的控制软件。结果发现，6 轴控制加工揭示了精加工具有良好表面粗糙度的可能性。其次，该研究涉及开发使用非旋转切削刀具在雕刻表面上进行非对称切槽的软件系统。刀具的形状与凹槽的横截面相同。 3轴至5轴控制无法加工的非对称切槽是6轴控制加工的特征之一。该系统由两个阶段组成：第一阶段是定义具有不对称横截面的凹槽路径和凹槽形状，第二步是将凹槽路径粘贴到工件表面上，并生成与凹槽形状相对应的CL数据，同时考虑到过切和碰撞。生成的 CL 数据随后由后处理器转换为 6 轴控制加工中心的 NC 数据。该软件系统展示了6轴非对称切槽的有效性。
