Abstract
In the fields of machining process, 3D models are used for the purpose of representing motions of tool and workpiece. However, 3D models can't describe changes of state to time direction continuously, so representing machining process efficiently is difficult. The objective of this study is to represent 5-axis cutting processes explicitly by using 4D mesh models, which can describe changes of state to time direction continuously. In order to show the availability of 4D representation, tool and workpiece are defined as "4D models of accumulated volume" which have information of motion records. In this report, 4D mesh models are obtained from time-series data of 3D voxel models which are made from 5-axis cutting simulation. Generated 4D mesh models are observed as 3D models by cross-section extraction. Also, cutting areas are obtained by collision detection between tool and workpiece.
