Development of advanced CAD/CAM techniques for high-performance 5-axis milling of sculptured parts

随着CAD/CAM技术的进步，具有雕刻零件的机械产品已广泛应用于航空、汽车、模具等行业，这些行业一直致力于更好的质量和更高的生产率。由于数控加工通常可以使零件质量更好，成本更低，交货时间更短，因此它是制造业中的一项重要技术。然而，作为一流的，高性能的五轴加工的雕刻零件仍然是一个巨大的挑战，即使这种技术是迫切需要的。造成这种情况的主要原因是一些关键技术尚未成功解决。申请人提出了先进的、创新的关键技术研究，包括(i)五轴雕刻零件加工的刀具尺寸优化，（ii） NURBS刀具路径生成以获得光滑、精确的表面，以及（iii）在五轴表面铣削中高效、精确的刀具/工件啮合。

With the advances of CAD/CAM technology, mechanical products with sculptured parts have been widely adopted in the aeronautical, automotive, and dies/molds industries, which always commit to better quality and higher productivity. Since CNC machining generally can make the parts with better quality, less costs, and shorter lead time, it is an important technique in the manufacturing industry. However, as top-notch, high performance 5-axis machining of the sculptured parts is still a great challenge, even though this technique is badly needed. The main reason for this is that some key techniques have not yet been successfully addressed. The applicant proposes advanced, innovative research on the key techniques, including (i) cutter size optimization for 5-axis sculptured part machining, (ii) NURBS tool path generation to make smooth, accurate surfaces, and (iii) efficient, accurate cutter/workpiece engagement in 5-axis surface milling.
