Accordingly, the project approving of the task has important sense to solving afore-mentioned problems. Graph the innovation that technology of dialog box of editor of system of 1 fast process designing studies and breakthrough plane are sophisticated structural member is fast the three-dimensional digitlization model with the spare parts is system of numerical control process designing foundation, broke through a series of crucial technologies, include: Compositive and get through design of program of CNC Machining program, procedure, to program, be out of shape the treatment such as analysis and postposition processing prepares crucial segment, came true fast on same platform, efficient begin CNC Machining of plane component part to intend each work with high quality ground, raised process designing of technology design, CNC Machining to wait for the effectiveness of individual technology and each tool to the greastest extent thereby, make these technical tools develop the biggest efficiency; Automatic compose is built and dredge data of CNC Machining preparation flows, make the preparative data such as layout of program of among them treatment program, procedure, numerical control, clamping apparatus and treatment code is able to deliver directly, use, feedback and save, avoided many repetition to be inputted by hand thereby, reduced treatment to prepare the interactive quantity in the process significantly; Mix in library of equipment of technology knowledge base, machine tool, cutting tool library below the support of the library of treatment natural resources such as cutting parameter library and technology of relevant knowledge drive, come true and offerred each intelligence to change the treatment with automation to prepare a function, promoted the automation that machines preparative process the standard, shortened treatment plans time. The plane is sophisticated structural member is fast system of numerical control process designing is platform with CATIA environment, developed corresponding functional module, if the ministry interface that shows actually pursues 1 ～ graph is shown 4 times. Graph information of 2 spare partses and plane of plan of similar treatment program are sophisticated the main innovation dot of system of process designing of quick numerical control includes structural member: 1.

Compose is built and developed " the plane is sophisticated structural member is fast system of numerical control process designing " structural system. This construction system builds the base of three-dimensional digitlization model in the spare parts, relatively system and be reflected well and truly and supported a plane craft of CNC Machining of complex component part prepares those who reach process designing to specialization flow. 2.

Put forward and formed relatively complete " CNC Machining automatic process designing " theory and technical system, solved the plane such as such as wainscot well complex component part machines a series of decisive issues in automatic process designing. Include among them: (1) the structural characteristic that is aimed at plane wainscot, creativity ground knife course statified the identifying that generates a technology to popularize application to machine a feature to component part and anatomical, area of the treatment in solving wainscot effectively to machine automatic process designing is gotten, the fundamental sex problem such as cutting tool choice and knife course computation; (2) automatic to existing cutting tool academic basis -- region of Voronoi Mountain definition and cutting outline 45? Unplug body undertakes correction, designed the cutting tool that is based on geometrical character to choose algorithm automatically on this foundation, to be below the premise that makes sure treatment quality and handling time are the shortest, the amount that requires cutting tool certainly and dimension provided methodological basis; (3) according to classification program principle, with correlation of broad sense chamfer the tree is a foundation, compose established the diagnostic sort method at intellectual inference. Graph relevant technology of Nextpage of 3 treatment set is compared integratedly use to program relative to the artificial hand at convention, the plane is sophisticated system of process designing of quick numerical control has structural member the following advantage: 1.

The efficiency of to program is tall. The process designing time of common structural member is in 30 ～ 60min, the process designing time of more complex part is in 1 ～ 4h, the process designing time of the largest part is in 30 ～ 40h. 2.

Workload decreases apparently. To using convention process designing means needs to click the process designing of a structural member with achievable ability on the mouse 10 thousand times, when use PrtRMP system, need to click a mouse a few times only. 3.

Program repeatability is good, form standard mode easily. Be the same as the spare parts of kind of type, the order of the spare parts machine program that the system weaves and method are identical, and the experience that artificial process designing needs to rely on an individual, mutual a difference is bigger. 4.

Cutting parameter is revised convenient. Usually, artificial process designing is mixed to revolution of feed changing is convenient, but reach greatly to cutting cut change very difficult implementation widely, because change,cut mix greatly cut wide, be equivalent to program of new authorized strength, the cycle of need is long. And use systematic process designing, after the parameter of cutting tool cutting in needing to will machine plan only is changed, undertake systematic process designing afresh, can get new program, come true easily accordingly. Graph 4 make treatment program pattern plate 5.

Can build a machine tool -- library of parameter of cutting tool cutting. Cutting parameter library is machine a database with add a company very important, whether can form effective cutting parameter library, represent the process capability level of an enterprise. If to program is a kind of burden no longer, so, technologist can put more energy optimize cutting parameter to go up, such ability build an effective machine tool quite - library of parameter of cutting tool cutting. The plane is sophisticated system of process designing of quick numerical control and photograph of domestic and international relevant technology compare structural member if has advantage expresses place to show. System of this fast process designing prepares spare parts CNC Machining to regard as specialization thoroughly the process will consider, compositive among them each relevant technology and tool, made formation synthesization system, so that be on same system,each preparation that be begun effectively and finishs spare parts CNC Machining works, achieve international consequently banner level. Perspective of research achievement application is wide the plane is sophisticated system of process designing of quick numerical control is using structural member stability moves in the process, the effect is distinct. Current, shenyang aircraft industry (group) limited company (the following abbreviation " Shen Fei " ) the treatment of the multinomial part that already used this system to achieve the kind such as wainscot, bridge, costal region and casing intends the work, shorten on average treatment preparation time amounts to 70% above, raise treatment effect to lead 30% above. Be worth what carry is, those who regard 2013 year as special support " the demonstrative application of system of high-grade numerical control in aviation domain " the task assumes an unit, shen Fei and China in numerical control Inc. is ensure of the task carry out satisfactorily, fly to Shenyang ahead of schedule partial machine tool undertook system of homebred numerical control transform, the plane received success application on the system of homebred numerical control after system of process designing of quick numerical control also is transforming complex structural member. Henceforth, the plane is sophisticated system of process designing of quick numerical control returns structural member will be arrived to grind newly by comprehensive promotion application the plane of model makes a process in. In the meantime, this system also will be gone to by promotion application in other aviation production industry. Enterprise innovation ability obtains promotion to carry out a proof, the plane is sophisticated system of process designing of quick numerical control already had structural member stronger intelligence changes a standard, sex of the look up before the certain and crucial technology that uses among them is had and innovation sex, can realize the technical renovation that CNC Machining of complex component part plans the plane, and from go up at all solve current aircraft the bottleneck problem that in planning a course, CNC Machining of complex component part faces.
