Abstract
While the usage of 5-axis machine has dramatically expanded, issues for application technology of 5-axis machine such as collision remain in practical use. Recently, the usage of Geometric simulation before cutting to prevent collision has prevailed in 5-axis and multitasking machine. However, collision accident when used manually still occurs, and both user and machine builder are highly focusing in collision free machining. In this paper, a development of on-line collision check system that is used by Geometric simulator and CNC openness is presented, and discuss the effectiveness.
