1. A example of complex curve is actualized.

2. Furthermore, an NC program of dealing with complex curve contact rollers has been developed.

3. In the process of NC machining complex curve, there is error between interpolation tool path and theoretic tool path, which lead to the error between actual curve and theoretic curve.

4. Algorithm of geometry simulation in machining complex curve surface depending on engagement theory is the new exploration for geometry simulation, it has better practical meaning.

5. This complex curve gives them more tension, and suggests that there are forces acting on them from two different directions.

6. The results show that the rate of the growth of each point on the surface crack is connected with the place of crack and the structure of nozzle, and its steady shape is some of complex curve.

7. With the development of the science and technology, there are more and more products with complex curve, and the requirement of the process accuracy keeps increasing.

8. The real time correcting link is set up by using the complex curve fitting method, and the correction is implemented on line.

9. On the one hand, it is caused by the improperly-prepared operators before the machining; on the other hand, it is caused by the complex curve programming error.

10. Micro linear segments are generated by CAM system in surface machining to approach the complex curve.

11. The genetic algorithms with canonicity real number encoding is proposed, establishing a math model of flat complex curve form error and calculating it with genetic algorithms of real number encoding.

12. The cut cell method had a good adaptability to the curve boundary and could overcome the defect that the FDM adopt the zigzag on the curve boundary and was suit for arbitrary complex curve casting.

13. The XB4450 imitating milling machine transformation is four axes three linkages numerical control milling machines. It may process the complex curve, the curved surface.

14. But the cylinder and the cylinder intersect, then bite on the generation of complex curve.

15. LTD, the new type of bonding pad roll with complex curve roller contour is design, it avoid point and arc touching between the bevel edge of outside welding and roller sur.
