项目摘要

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 is equipped with a main spindle cpable of tool orientation in addition to conventional 5-axis control sturcture. Non-rotational cutting tool is mounted at the main spindle to carry out the 6-axis control machining, which allows a variety of machining possibilities. The study deals with the development of a software system for corner shaping by use of a non-rotational cutting tool. Conrner shaping is one of typical examples of 6-axis control machining. The corner shape formed by conventional rotational tools has a round, which is impossible to remove without manual finishing. Thus, a non-rotational cutting tool was developed to remove the remaining. The tool can not only finish a sculptured surface of a corner with the side cutting edge, but also form a sharp curved line of a corner with the top cutting edge. A sharp curved line without a round is obtained by feeding the non-rotational cutting tool along the curved line, while keeping the cutting edge tangent to the sculptured surface. From an experimental result of corner shaping, it is found that the system is valid to obtain workpieces consisting of sculptured surfaces without round conrner. The method is further expanded to machine a pocket milling consisting of planes and sculptured surfaces. A non-rotational cutting tool is fed along with a cross-sectional curved line between sculptured surface and a given plane. A generated CL data are transformed to the actual 6-axis control NC data. The validity of CAM software developed in the study is also found from experimental results.

该研究通过使用6轴控制来处理新的加工概念。 6轴控制表明，切割工具允许三个旋转运动以及三个转换工具。除常规的5轴控制稳固外，一个6轴控制加工中心还配备了刀具方向的主轴。非旋转切割工具安装在主轴上，以进行6轴控制加工，从而允许各种加工的可能性。该研究涉及通过使用非旋转切割工具的软件系统开发用于角落塑造的。 Conrner塑形是6轴控制加工的典型示例之一。传统旋转工具形成的角形具有一个圆形，如果没有手动完成，这是不可能删除的。因此，开发了一种非旋转切割工具来消除其余的。该工具不仅可以用侧切边缘完成角落的雕刻表面，而且还可以形成带顶端边缘的角落的锋利弯曲线。通过沿弯曲线喂食非旋转切割工具，在保持雕塑表面的切割线时，获得了无圆的尖曲线。根据角塑形的实验结果，可以发现该系统有效获取由雕刻表面组成的工件，而没有圆形的conrner。该方法进一步扩展到机器，以机器铣削，由平面和雕塑表面组成。非旋转切割工具与雕刻表面和给定平面之间的横截面弯曲线一起喂食。生成的CL数据转换为实际的6轴控制NC数据。从实验结果中也发现了研究中CAM软件的有效性。
