The NC Simulator is widely used to reduce machining time since it can verify shapes after machining and the tool path without actual machining processes. NC Simulators currently used have been developed with emphasis mainly on speedy presentation of shapes after machining. Consequently, the geometric accuracy of these simulators varied depending on viewpoints and the size of a screen. The purpose of this study is the development of a speedy and accurate NC Simulator based on a Boundary-Map geometric model. The Boundary-Map geometric model we are proposing is a solid model developed to accommodate CAM functions. This paper refers to three functions we have developed to use the Boundary-Map geometric model as a basic geometric model for the NC Simulator. The first is a function to create discrete point groups per interpolation cycle time according to the tool path. The second is a function to change a tool at a given point to Boundary-Map presentation. The third is a function to remove the tool shape from the work shape. The results are the achievement of speedy, accurate performance of the machining simulation by using the Boundary-Map geometric model.
