Visualization Process for Design and Manufacturing of End Mills Sung-Lim Ko, Trung-Thanh Pham, and Yong-Hyun Kim Department of Mechanical Design and Production Engineering, Konkuk University, CAESIT(Center for Advanced E-system Integration Technology), 1 Hwayang-dong, Kwangjin-gu, Seoul 143-701, South Korea slko@konkuk.ac.kr Abstract. The development of CAM system for design and manufacturing of end mills becomes a key approach to save the time and reduce cost for end mills manufacturing. This paper presents the calculation and simulation of CNC ma- chining end mill tools using on 5-axes CNC grinding machine tool. In this study the process of generation and simulation of grinding point data between the tool and the grinding wheels through the machined time are describes. Using input data of end mill geometry, wheels geometry, wheel setting, machine setting the end mill configuration and NC code for machining will be generated and visual- ized in 3 dimension before machining. The 3D visualizations of end mill manu- facturing was generated by using OpenGL in C++. 1 Introduction The flat end mills are commonly used in industry for high speed machining. They are characterized by a complex geometry with many geometric parameters, which deals with some complicated processes in machining with grinding CNC machine. In the previous studies by Ko [1, 2], the development of CAM system was limited in 2D cross sections of the tools and the results of simulation were restricted to the main fluting operation. Ko already provided a machining simulation for specific 5-axes machines in 2D. Dani Tost pre
