Abstract
The paper deals with a CAM kernel independent of platforms. In the recent years, CAD modeler have become popular. However the products using domestic kernel have been decreased. Moreover, efficiency of development of a software is made lower by dependency on a platform. We are aiming to develop open CAM kernel independent from platforms. IGES a general-purpose intermediate format of three-dimensional CAD data is used in the system as a native format. In this paper, we report outline of the system and a sample CAM system based on the system.
