The development of manufacturing market demands that 3-axis machining technology is never enough. As a highly automated intelligent processing equipment, 5-axis machining center is often used in high-end manufacturing. Five axis machining center is suitable for machining airframe parts of free-form surface, turbine parts of aircraft and ships and impeller. We can find that all the workpieces suitable for five axis machining center have the characteristics of high degree of curved surface and difficult to be processed and formed by one-time clamping. Therefore, the five axis machine tool can process the different sides of the workpieces without changing the position of the workpieces on the machine tool, greatly improving the processing efficiency of the prismatic parts. The five axis machining center has three moving axes x, y, Z and any two rotating axes. Compared with the traditional three axis machining center, the five axis linkage technology of the five axis machining center can locate and operate on five degrees of freedom when machining the workpiece with complex geometry.

很多朋友在了解五軸加工中心方面存在一個誤區，認為五軸加工中心就是在三軸加工中心的基礎上，添加2個旋轉軸。這兩個旋轉軸先將切削刀具固定在一個傾斜位置，再由進給軸X、Y、Z進行移動和加工。這種加工方式實際上是由于第四軸和第五軸是用來確定在固定位置上刀具的方向，而不是在加工過程中連續不斷的運行。因此這不是真正的五軸聯動技術，3+2軸的加工中心可以滿足普通加工中心無法完成的加工操作，但這也并不是真正的五軸加工中心。

Many friends have a mistake in understanding five axis machining center. They think that five axis machining center is to add two rotating shafts on the basis of three axis machining center. The two rotating axes fix the cutting tool in an inclined position, and then the feeding axes x, y, Z move and process. In fact, the fourth axis and the fifth axis are used to determine the direction of the tool in a fixed position, rather than continuous operation in the process of machining. Therefore, this is not a real five axis linkage technology. 3 + 2 axis machining center can meet the processing operations that ordinary machining centers cannot complete, but this is not a real five axis machining center.

真正的五軸加工中心具備刀點跟隨功能，可以在不改變任何參數的情況下，確保高效的刀具的切削點和零件表面接觸，避免造成切削陷坑。整個路徑運動過程中可對刀具方向進行優化，同時進行刀具直線運動。這樣，在整個路徑上都可保持最佳切削狀態。五軸加工中心在刀具應用和加工優化這一塊也是非常重要，五軸加工中心目前在加工異面體加工、葉輪加工、箱體加工、齒輪加工、復雜腔體應用特別多。對一個國家的航空航天、軍事科研、精密器械、汽車設備、高精醫療設備等領域有著舉足輕重的影響力。

The real five axis machining center has the function of tool point following, which can ensure that the cutting point of the efficient tool contacts with the surface of the part without changing any parameters, so as to avoid the cutting pit. In the whole path movement process, the direction of the tool can be optimized, and the straight-line movement of the tool can be carried out at the same time. In this way, the best cutting state can be maintained in the whole path. Five axis machining center is also very important in tool application and machining optimization. At present, five axis machining center is widely used in machining different surfaces, impellers, boxes, gears and complex cavities. It plays an important role in aerospace, military research, precision equipment, automotive equipment, high-precision medical equipment and other fields of a country.

曲面制品關于現代人生活來說并不生疏，大到轎車、游艇美觀漂亮的形體，小到手機、電腦鼠標之精美的外殼，曲面制品隨處可見，并且花樣、種類日益更新。曲面零件的出產進程離不開CNC數控機床。曲面產品在制作時，首先要由CNC數控機床加工出帶有曲面形狀的模具，然后由模具成批地復制出終究的產品。為此，CNC數控機床已成為當今現代化工業出產中最重要的機器設備。

Curved surface products are not new to modern life, ranging from beautiful shapes of cars and yachts to beautiful shells of mobile phones and computer mice. Curved surface products can be seen everywhere, and patterns and types are increasingly updated. The production process of curved surface parts is inseparable from CNC machine tools. In the manufacture of curved surface products, the mould with curved surface shape should be processed by CNC machine first, and then the final products should be copied by the mould in batches. Therefore, CNC machine tool has become the most important machine equipment in modern industrial production.

但是CNC數控機床加工曲面零件時的出產功率和加工質量并不盡如人意，原因是CNC數控機床必須使用球面銑刀，以防止刀具過切（即刀具將不應切除的工件資料刮掉，破壞了工件的造型）。球面銑刀之圓滑外表易于適應曲面零件的雜亂造型，不會與工件外表發作干涉，但是卻嚴重地妨礙了CNC數控機床出產功率的正常發揮，一起也降低了產品的加工質量。長久以來，國內外專家、業者一直在研究代替球面銑刀、提高CNC機床出產功率的辦法。端銑刀能夠極大地提高CNC數控機床加工曲面制品時的出產功率，零件外表的加工質量也會得到根本性的改善。然而端銑刀的平直底面不易適應曲面零件的雜亂形狀，會常常引發刀具的過切問題，形成工件產品的報廢。因而實際出產中，端銑刀還沒有被用于曲面零件的加工制作；并且在五軸刀具切削問題不能得到徹底解決以前，端銑刀根本無法使用于曲面零件的加工。

However, the production power and processing quality of CNC machine tools in machining curved parts are not satisfactory, because the CNC machine tools must use spherical milling cutter to prevent the cutter from over cutting (that is, the cutter scrapes off the information of the workpiece that should not be cut and destroys the shape of the workpiece). The smooth surface of the spherical milling cutter is easy to adapt to the disordered modeling of curved parts, and will not interfere with the surface of the workpiece. However, it seriously hinders the normal production power of CNC machine tools and reduces the processing quality of the products. For a long time, experts and manufacturers at home and abroad have been studying ways to replace the spherical milling cutter and improve the output power of CNC machine tools. The end milling cutter can greatly improve the output power of CNC machining curved surface products, and the machining quality of the part surface will also be fundamentally improved. However, the flat bottom of the end milling cutter is not easy to adapt to the disordered shape of curved parts, which often leads to the over cutting problem of the cutter and the scrap of workpiece products. Therefore, in the actual production, the end milling cutter has not been used in the processing and manufacturing of curved surface parts; and before the five axis cutting problem can not be completely solved, the end milling cutter can not be used in the processing of curved surface parts at all.

The international technical problem of cutter over cutting when the efficient five axis milling cutter is used to cut curved surface parts has been solved by Dr. Wang Yin, the creator of this project, and an effective method of rapid cutting curved surface parts with end milling cutter has been established. Thus, the end milling cutter can replace the spherical milling cutter and be used in the machining of curved surface parts. The application of the advanced technology of surface rapid cutting will fundamentally improve the disadvantages of CNC machine tools, such as high working hours, poor processing quality, long manufacturing cycle, etc., and give full play to the functional advantages of CNC machine tools.
