隨著我國高級科學技術工業的迅速發展，對機械產品的要求越來越高，如何提高機械產品的生產效能和品質、降低產品成本，及機器設備的投資，這就對刀具的材質、刀具的使用壽命以及刀具的加工效率，提出了很高的要求。
車床為機械加工中常見的工作母機之一，車床主要用於加工對稱形或圓柱形的零件，是機械製造和修配工廠中使用最廣的工具機。為達到物美價廉的產品，大量生產是必須製程，在傳統車床加工中，利用成形車刀的優點，可以達到節省生產設備，且加工品質穩定、表面粗糙度佳。
本文也對螺旋曲面車床加工進行研究，探討螺旋曲面形狀特性，及刀具路徑產生等有關方面的理論探討， 利用已知螺旋曲面的擺線截面逆算求解來設計成形車刀刃口外形，可作為此類相關研究之參考。
多角外形多邊車削目前在業界使用日漸普遍 ，一般技術也很成熟，但只知道如何運用理論，其實多角外形車多邊形是一個近似值，許多人只知道是近似值，不知道真正誤差的數值，本文將計算出真正的誤差值。
關鍵字：成形車刀、表面粗糙度、多角外形

With its advanced rapid development of science and technology industry, the rapid development of the increasingly high demand for mechanical products, mechanical products, how to improve production efficiency and quality, reduce product costs, and equipment investment, which the tool material, tool processing efficiency and tool life, made a very high demand.
Lathe machining of common machine tools, lathe-shaped or cylindrical symmetry for processing parts, machinery manufacturing and repair facility is the most widely used machine tools. In order to achieve cost-effective products, mass production processes must be in the traditional lathe, using the advantages of forming turning tools, you can achieve savings in production equipment, and processing quality and stability, the surface roughness good.
This lathe also studied spiral surface, the surface shape of spiral features, and tool path generation and other relevant theoretical study, using the known surface of the cycloid spiral cross-section forming the inverse operator to design the vehicle to solve the blade shape of the mouth, such as reference to related research.
Polygonal shape of the current multilateral turning increasingly common use in the industry, the general technology is very mature, but only know how to use the theory, in fact, the polygon is a polygonal approximation of shape car, many people only know the approximate, do not know the true value of the error, this will calculate the real error.
Keywords: Form Turning Tools, surface roughness, polygonal shape
