5축 레이저 컷팅기 전용 CAM 시스템 개발

5-axis laser cutting has great advantages when it is applied to 3-dimensional machining requiring high cutting quality. For developing 5-axis CNC laser cutting systems, however, many problems such as rotating a laser head or a working table, 5-axis servo-control mechanism, tool path generation and post processing, and collision avoidance between a laser head and a work-piece should be solved. In this paper, we develop a prototype system of 5-axis laser cutting machine. A table-titling type is adopted as a machine configuration and servo-control mechanism of five axes is implemented on the machine. CL data generation and post processing methods for five-axis CNC machine are also developed.
