A study on the design of CNC lathe for education and application
Abstract As the factory automation progresses, the number of specialized products increases rapidly. Furthermore, there is an increased need for engineers trained in CAD/CAM for process design and operation. This development necessitates thorough and systematic education in CAD/CAM and educational numerical control machine tools. Inexpensive educational CNC machine tools will facilitate the required education in Korea. In this study we design and manufacture a prototype of an inexpensive CNC lathe. This will facilitate the CNC education in Korea as these activities become active. The designed CNC lathe has power rating of 0.5 kW and includes a CPU board, main motor board, step motor board, and power supply board. The specification for lathe meets the KS and DIN standards.
Eğitim Tipi CNC Freze Tezgâhi Prototip Tasarimi ve İmalati
In today’s manufacturing industry, any products are manufactured by using CNC (Computer Numerical Control) machine. CNC machine developed and sustained its improvement becoming an indispensable part of manufacturing sector. In order to educate operators that would use CNC machine which have important role for manufacturing industry; theoretical courses such as basic level machine utilization, machine programming is given at vocational schools, vocational high-schools and faculties. However; this information is not given practically in most of the engineering faculty. The reason for this is not being able to purchase expensive CNC machine by faculty and maintenance services being ineffective. In this study, low-cost education set that would enable more active learning in which students who are taught CNC education can practice on their own was designed, its prototype was produced and application was done.
The Integration of CAD and CAM by Application of Artificial-Intelligence Techniques
This paper reports on the development of a new type of process planning system by application of two artifical-intelligence techniques: “Production system” and “Backtrack search”. This system can automatically generate the optimum machining sequence for the finished geometry in the data base given as the out-put from the CAD system. This system uses empirical knowledge about machining stylized into Production Rules, and a separate deductive algorithm. The system is written in PASCAL which permits use of user-defined data structures and recursion. These features bring flexibility, generality, and simplicity to the system. The results are put into an EXAPT part program which is ready for execution. This allows for the integration of COMPAC and EXAPT.
