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.
CNC Desktop Vertical Machining Bench Design and Cooling Fluid Application
Today's manufacturing technologies, the human work force is used and at least a minimum level of margin of error is used in CNC machines. Desktop CNC machine tools and CNC machine tools are developed in parallel with the development of personal computers. This study provides CNC training institutions for education, small and medium-sized enterprises for commercial purposes use the low-cost desktop machine has been designing and manufacturing of CNC vertical machining was carried out. Desktop CNC machine tools and production capacity to handle the kind of material was applied to increase the cooling fluid. Through A199 and Fe37 the cooling fluid application desktop CNC machine tools, such as processing of materials that are difficult to successfully processed.

TOJICAP — A System of Computer Aided Process Planning System for Rotational Parts
Summary This paper presents an interactive computer aided process planning system for rotational parts. This system has been created at Tongji University and named “TOJICAP”. It was designed to run on the VICTOR 9000 microcomputer and its program has been written in MS-BASIC. Through the use of the principle of group technology and according to the standard plans of Master Parts, the planning sheet of new part in certain family can be generated automatically. This system also provides the interactive approach by which the user can plan the process step by step for any other rotational part that is not included in part family. The output of system - planning sheet is easy in editing, modifying and completing. By means of TOJICAP system the efficiency of planners can be increased greatly. The operation of TOJICAP system is simple and the benefits are remarkable. In this paper, the principle and structure of TOJICAP system are described, and an example is illustrated.
