| Research Abstract |
The objectives of the research have been successfully attained after two years of research. The major research results obtained are as follows; 1. Design and manufacture of ultra-precision intelligent machining control system The main part of the system was designed and manufactured according to the original plan. The main body is made of super-invar in order to cope with the thermal and dynamic problems. 2. Development of knowledge base and control algorithms for intelligent control The softwares were developed for the intelligent control of the system and implemented to a 16bit personal computer. 3. Analysis and evaluation of fundamental properties of developed system The accuracy, the rigldlty, the thermal property and the dynamic response of the developed system were mainly analyzed and evaluated. It is confirmed that the system performance Is satisfactory. 4. Evaluation of cutting performance of developed machining control system The system was engaged in actual ultra-precision cutting tests of various metals. It Is confirmed that the system performance is satisfactory. 5. Evaluation of overall performance of developed system The hardware, the software, the cutting performance and the ease of usage of the developed system were tested. It was confirmed that the system performance is satisfactory. 6. Examination of system for practical application The system was evaluated in order to put to practical use In actual production shop.
