| More and more people come to like the relief sculpture due to its peculiar artistic glamour. So the demand of the relief sculpture artwork has greatly increased. To make suitable to this change, what we can do is to introduce the advanced CAD/CAM technology to improve the traditional manufacturing process of the relief sculpture. This paper introduces an ObjectARX application - 3D relief sculpture CAD/CAM software system, which works inside AutoCAD 2000. We select ObjectARX 2000 as our major development tool, as it provides an object-oriented C++ application programming interface and helps us develop fast, efficient, compact applications.As will be discussed in the next chapter, we have taken many advanced technologies to solve various problems of our task. Some major technologies are as follows:?To simplify the design of 3D object, we adopt layer-based design thought throughout this system.?To make the solid have realistic surface, we adopt advanced solid modeling method -Constructive Solid Geometry.?To free end-user from overwork, we presents and realizes many auto-processing algorithms, such as searching of inner-point, definition of polygon's counter-clockwise direction, as well as generation of numeric control codes. ?To checkout the collision and interference between cutter and part, we accomplish numeric control machining simulation, which can help end-user validate the correctness and rationality of numeric control codes, so it is needless that do repetitive test-cut before normal manufacture.Due to the exertion of these advanced CAD/CAM's technologies, the enterprises are able to meet needs of the variable market requirements with the quickest speed, the best quality, the lowest cost, the most excellent service. So the enterprise can take up the advantageous position in the high-efficiency, high-quality and high-technology market competition. |
