| Research Abstract |
The demand for efficient and accurate machine tools and machining technology is rapidly increasing in recent years. The intensive manufacturing technology capable of the whole machining at one setup allows machine tools to realize the efficient and accurate machining. The study proposes a new machining method of combining sophisticated. 5-axis control machining with 6-axis control, one using non-rotational cutting tools. However, the cutting speed of 6-axis control machining is low, which causes the deterioration of machined surface quality. Thus, the ultrasonic vibrational cutting was employed to solve the problem. The study is summarized as follows :
1. The-main processor to generate cutter path (CL) data for 6-axis control machining, based on workpiece shapes defined by 3D-CAD system, was developed, especially for character line machining and asymmetric grooving, taking account of collision avoidance between tool and workpiece.
2. Cutting experiments by use of a vibration tool were carried out on a 6-axis control machining center with NC data converted from CL data by use of our own post processor. As a result, the workpiece with fine surface quality can be obtained.
3. A part of the integrated multi-axis control CAM system was achieved to perform the efficient machining ,by unifying the effective 5-axis control CAM system and the 6-axis control one developed in the study.
