Data Formats and Slicing Algorithms for CAD/CAM of Ideal Functional Material Components

Ideal Functional Material Components (IFMC) is designed with optimum functional performance,and is constructed by homogeneous materials,composite materials,functionally gradient materials,and functional mi-crostructure.For its Digital Concurrent Design and Manufacturing (DCDM),it is urgent to construct and acquire the information of IFMC.Data formats and slicing algorithms for DCDMof certain IFMC composed of homogeneous materials,composite materials and functionally gradient materials (FGM) are presented.The simplex-subdivisionbased data formats are used to represent the whole geometry,topology and material information of IFMC.Based on the data formats,a uniform slicing algorithm,which is verified by an example,is developed.
