汽車進氣門刀具的設計與制造(含CAD零件圖,PROE三維圖)(論文說明書10000字,CAD圖紙1張,PROE三維圖)
 摘 要:切削加工是現代制造業應用最廣泛的加工技術之一。據統計,國外切削加工在整個制造加工中所占比例約為80%~85%,而在國內這一比例則高達90%。  刀具是切削加工中不可缺少的重要工具,無論是普通機床,還是先進的數控機床(NC)、加工中心(MC)和柔性制造系統(FMC),都必須依靠刀具才能完成切削加工。刀具的發展對提高生產率和加工質量具有直接影響。材料、結構和幾何形狀是決定刀具切削性能的三要素,其中刀具材料的性能起著關鍵性作用。國際生產工程學會(CIRP)在一項研究報告中指出:“由于刀具材料的改進,允許的切削速度每隔l0年幾乎提高一倍”。刀具材料已從20世紀初的高速鋼、硬質合金發展到現在的高性能陶瓷、超硬材料等,耐熱溫度已由500~600℃提高到1200℃以上,允許切削速度已超過1000m/min,使切削加工生產率在不到100年時間內提高了100多倍。因此可以說,刀具材料的發展歷程實際上反映了切削加工技術的發展史。

Abstract :Cutting is one of the most widely used processing technologies in modern manufacturing industry. According to statistics, the proportion of foreign cutting processing in the whole manufacturing process is about 80%-85%, while in China the proportion is as high as 90%. Tool is an indispensable and important tool in cutting. Whether it is an ordinary machine tool, or an advanced numerical control machine tool (NC), a machining center (MC) and a flexible manufacturing system (FMC), it must rely on the tool to complete the cutting process. The development of cutting tools has a direct impact on improving productivity and processing quality. Material, structure and geometric shape are the three factors that determine the cutting performance of the tool, and the performance of the tool material plays a key role. The International Society of Production Engineering (CIRP) pointed out in a research report that "due to the improvement of tool materials, the allowable cutting speed almost doubles every 10 years". Tool materials have been developed from high-speed steel and cemented carbide in the early 20th century to high-performance ceramics and superhard materials. The heat-resistant temperature has been raised from 500-600 degrees C to over 1200 degrees C, the allowable cutting speed has exceeded 1000m/min, and the cutting productivity has increased more than 100 times in less than 100 years. Therefore, it can be said that the development history of tool materials actually reflects the development history of cutting technology.
Key words: turning tool, manufacturing, processing, cutting tool
