在工程技术和科学实验中,经常遇到大型的复杂函数曲面构件,人们曾对其加工方法进行了很多研究,取得了一些成果,但是,在曲面函数复杂,加工精度和表面光洁度要求高的情况下,往往难以达到设计要求。因此大型复杂函数曲面的加工问题长期以来仍是一个难题。准线成型法(又称母线轨迹成型法)是通过探讨风洞喷管气动型面的加工 In engineering and scientific experiments, often encountered large complex function surface elements, people have done a lot of research on its processing methods, and achieved some results, but in complex surface functions, machining accuracy and surface finish demanding Under the often difficult to meet the design requirements. Therefore, the problem of machining large complex function surfaces has long been a problem. Quasi-line forming method (also known as bus trajectory forming method) is to explore the wind tunnel nozzle pneumatic surface processing
