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.

随着CAD/CAM技术的进步，带雕塑零件的机械产品在航空、汽车和模具行业得到了广泛的应用，这些行业总是致力于更好的质量和更高的生产率。由于数控加工一般可以制造出质量更好、成本更低、制造周期更短的零件，因此它是制造业中的一项重要技术。然而，作为一流的、高性能的五轴联动加工，雕塑零件的加工仍然是一个巨大的挑战，尽管这项技术是非常必要的。造成这种情况的主要原因是一些关键技术尚未成功解决。申请人建议对关键技术进行先进的创新研究，包括(I)5轴复杂零件加工的刀具尺寸优化，(Ii)用于制造光滑、精确曲面的NURBS刀具路径生成，以及(Iii)5轴曲面铣削中高效、准确的刀具/工件啮合。
