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，具有雕塑零件的机械产品在航空，汽车和模具/模具行业中被广泛采用，这些产品总是致力于提高质量和更高的生产率。由于CNC加工通常可以使零件的质量更高，成本更低和交货时间较短，因此它是制造业中的重要技术。但是，作为一流的雕塑零件的高性能5轴加工仍然是一个巨大的挑战，即使这种技术非常需要。这样做的主要原因是尚未成功解决某些关键技术。 申请人提出了有关关键技术的高级，创新的研究，包括（i）5轴雕刻零件加工的切割器尺寸优化，（ii）NURB工件参与5轴表面铣削。
