项目摘要

The purpose of this research work is a development of basic software package useful for manufacturing high-quality molds and dies automatically without the assistance of skillful manufacturing engineers. In this three years project, the following technologies for the skill-less manufacturing are realized;1. We developed a new method for accelerating the inverse offset computation of the part surface, which is the most important computation for generating the milling path. This technology can achieve 10 to 100 times acceleration by using the 3D graphics devices equipped in personal computers.2. Laser sintering is a promising technology for fabricating mold and die directly from its solid model in computers. We develop a new fabrication system based on our "green tape" technology and did several experiments for evaluating the manufacturing time and surface quality of the fabricated objects using this technology.3. Subdivision surface technique is known as a powerful method for generating a smooth surface based on a set of point data on the surface. This technology is applicable for generating a high-quality milling path running through some measured points on the inverse offset surface of the object.4. By properly changing the tool orientation in machining, further quality improvement of the machined surface is possible. We developed several basic algorithms for efficiently determining the optimum tool orientation in such multi-axis machining process.

本研究工作的目的是开发一个基本的软件包，用于自动制造高质量的模具和模具，而无需熟练的制造工程师的帮助。在这三年的项目中，实现了以下无技能制造技术：1。提出了一种新的方法来加速零件曲面的反偏置计算，这是生成铣削路径的最重要的计算，该技术利用个人计算机中配备的3D图形设备可以实现10到100倍的加速.激光烧结是一种很有前途的模具制造技术，它可以直接从计算机中的实体模型制造模具。基于“绿色胶带”技术，我们开发了一种新的制造系统，并进行了几次实验，以评估使用该技术制造的物体的制造时间和表面质量.细分曲面技术是基于曲面上的点数据生成光滑曲面的一种有效方法。该技术适用于生成高质量的铣削路径，该路径通过物体反偏置曲面上的一些测量点.通过适当地改变加工中的刀具方向，可以进一步提高加工表面的质量。我们开发了几种基本算法来有效地确定此类多轴加工过程中的最佳刀具方向。
