Machine tool industry develops technology of 5 axes numerical control to have important sense
Come a few years, the only method that people thinks processing technique of 5 axes numerical control is to machine successive, flowing, complex curved surface generally. Once people is in design, make complex curved surface encounter inextricability difficult problem, can appeal 5 axes processing technique. Be in early 20 centuries 60 time, foreign aviation begins to use milling machine of 5 axes numerical control in industrial production. The application that at present 5 number of axle charge a machine tool still aviation of bureau be confined to, spaceflight reachs his relevant industry.
Numerical control of 5 axes linkage is the difficulty in numerical control technology the technology with the widest range of the biggest, application, drive of control of its collect computer, high-powered servo and accurate processing technique at an organic whole, apply at the efficient, nicety of complex curved surface, automation to machine. The regards a country as to produce equipment automation standard technology of numerical control of 5 axes linkage mark on international. As a result of its special status, especially the main effect to industry of aviation, spaceflight, military affairs, and the complexity on the technology, western industry developed country regards strategic goods and materials as to execute exit system of licensing system of 5 axes numerical control all the time, implement embargo to our country. Consequently, study processing technique of 5 axes numerical control is right of force of national science and technology and comprehensive national power rise have important sense.
Accord with the new way that numerical control machine tool develops
In last few years machine tool of international, home is exhibited make clear, numerical control machine tool forward high rate, high accuracy, compound the way that change develops. Compound the end that change is outfit clip is used to complete much or overall cutting treatment on a machine tool, in order to assure the positional precision of workpiece, improve treatment efficiency. Milling machine of boring of foreign numerical control, machining center is machined to get used to polyhedron and curved surface spare parts, all use much rod processing technique, include function of 5 axes linkage. Patulous on machining center function of 5 axes linkage, can improve the process capability of machining center greatly, of facilitating system farther compositive change. Industry of international machine tool appeared recently a new idea, namely all-purpose treatment, numerical control machine tool already can turning can undertake 5 axes milling is machined again. 5 number of axle accuse a machine tool to make clear in domestic and international actual application, its machine efficiency to be equivalent to machine tool of two 3 axes, OK even and complete leave out is certain and large the investment of automation production line, big political integrity restricted the time that covers an area of space and workpiece to be carried in the have enough to meet need between different production unit and expenditure.
