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 WATER JET SET DESIGN FOR EDUCATIONAL PURPOSES AND ITS IMPLEMENTATION
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 are given at vocational schools, vocational high-schools and faculties. However; these information are not given practically in most of the educational institution. The reason for this is not being able to purchase expensive CNC machine by educational institution 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.
CAD/Generative process planning with TIPPS
Abstract Two approaches to computer aided process planning are defined—variant and generative. The variant approach retrieves existing plans for a similar part while the generative approach synthesizes plans from built-in knowledge. The generative approach to process planning is normally considered more complex and the more automated of the two approaches. This paper discusses a generative process planning system called Totally Integrated Process Planning System (TIPPS). TIPPS uses a computer aided design (CAD) model as direct input, eliminating part coding or description from the planning process. Currently, TIPPS is capable of planning prismatic parts with one access direction. Relevant issues encountered in constructing a generative process planning system as well as the TIPPS design philosophy are discussed. Process planning using TIPPS is illustrated. This paper also discusses future research directions in automated process planning.
