The shares workmanship informatization construction of natural resources of information of products plan, craft is the most important is to make full use of products plan graph and documentation resource, make full use of the experience of production treatment technology with company successful product, if use the three-dimensional graph of the product to be able to reduce the three-dimensional model time of personnel of numerical control process designing, and three-dimensional model expended numerical control process designing almost the time of 50% . The treatment technology that builds cutting tool information to machine library of material cutting parameter, outfit library, hard to place fixed position information, typical material and part and program pattern plate and expert database conduce to the quality that improves process designing and efficiency, should make full use of the craft information that PDM and network resource establish development company interior runs a system, share all production information resource that use possibly. 2.
CNC Machining and the craft of combinative numerical control that the tradition machines and common technology are sound join, the different characteristic that the most important is cost of precision of cycle of requirement of the design condition that is aimed at a product, batch, production, treatment, production takes different step respectively. In process of technology program design, the design condition that answers a product, design that machines clamping apparatus of means, tool is made, the concentration of the union of means of the choice of cutting tool, thick finish machining, working procedure differentiates, the respect such as the equipment current situation of the enterprise and ability will consider integratedly. The element such as the level that when applying actually, still needs to join business equipment ability, skilled worker and technical staff. Be aimed at development product and the treatment characteristic that approve manufacturing product, take the development that fits respective requirement craft and batch produce craft the way to deal with a situation, realize CNC Machining and the perfect union that the tradition machines. 3.
The collateral work out of numerical control craft and process designing is in the inchoate phase of craft, numerical control to program intervenes become passive to be active, can reduce the mistake of this type or risk greatly. In the work out process of the three-dimensional model that CNC Machining is having a product only and numerical control program, ability discovers the problem that exists in craft and program completely, because the program of numerical control craft and work out must assure,this is can process eligible product completely come out to stop, and unlike is common craft in that way, want to do not have a problem on the whole only, dimension was not omited, whether can the spare parts machine qualification completely to depend on the experience of skilled worker and level. Numerical control process is collateral the implementation of mode but from design product of three-dimensional CAD model share, the single person of numerical control process is in charge of making, what numerical control skilled worker participates in craft of the work out of numerical control program, CNC Machining and program is special and responsible make wait for a respect to come true. 4.
The standardization that the process of standardization numerical control that numerical control process weaves weaves reflected the standard that technology of enterprise oneself CNC Machining applies on certain level, will restrain the diversification of numerical control program through standardization, improve the quality of cutting tool contrail then, if fixed position is made clear in craft parameter of department of fiducial, fiducial to the knife, coordinate, cutting tool and cutting parameter. But contrail of compensation of the use of the treatment from 2 dimension outline, treatment of three-dimensional curved surface, fixed loop and subprogram, cutting tool, cutting tool is thick the many respects such as finish machining strategy undertake standardization process designing. On the foundation of treatment technology experience of typical spare parts, build the treatment craft pattern plate of standardization and pattern plate of numerical control program, the treatment efficiency of the quality that can improve process substantially and product. 5.
The detailed list of equipment of the content that the numerical control program that the database of numerical control process runs clamping apparatus of parts of pair of different type product, tool, mould presses process labor situation, numerical control, cutting tool, program concentration that undertakes is based on database system manages, avoid the flaw of the management of traditional folder form, use 2 times of convenient program already, inquiry, editor is revised etc use, the order government that can save numerical control personnel again and search time, avoid program mistake to use, the repetition of the program of numerical control of missing or akin product that avoids a program weaves. 6.
The application that Vericut machine tool processes emulation software is machined to 5 coordinate and machine quantitative change to turn bigger situation, it is OK to use Vericut software implementation avoids the collision interference end that optimizes cutting tool contrail. 2, one of elements that the uses horizontal CAD/CAM software application level that raises CAD/CAM software is level of application of CNC Machining technology. Numerical control should take pattern of logical modelling process designing according to the characteristic of the product when process designing. 1.
The union of handiwork and CAM process designing makes full use of the process designing module that itself of system of machine tool of relevant numerical control offers, if numerical control milling machines rectangular chamfer, U form chamfer, bore to circulate, the end panel that CNC Turning machines, outside round loop treatment, the electrode of electric spark machine tool machines a function joltily, the expert of the discharge craft parameter that line cut machines chooses to wait, can raise the efficiency of numerical control process designing and validity substantially. 2.
When choosing what strategy of sound CAM process designing is undertaking the product machines a model to build, the specific characteristic that should machine an object in the light of the product is adopted effective and the measure of forthright. Press the place process designing that the product machines, multi-purpose the content at working procedure is more onefold, and the state of affairs with less interference, if the feature such as stage of aperture, groove, protruding is much,appear in the process designing to structural part and treatment. To the product treatment model has integral model, multi-purpose compare extent of much, interference at machining the content of working procedure the treatment of the feature such as much, complex curved surface. 3.
The use of pattern plate of numerical control process designing uses the pattern plate that CAM system founds him user, try repeated usage can improve process designing efficiency greatly. For example, the optimal process definition when punch and sunken model will be being machined when production mould is treatment pattern plate, the geometrical system that needs to call pattern plate file to choose to need only when machining new similar product target starts this technological process can, the user passes treatment guide to be able to obtain the production process guidance of expert class easily from inside pattern plate, pass simple alternant, generate contrail of CNC Machining cutting tool quickly. 4.
The application of CAD/CAM expert system uses the functional module of CAD/CAM software, design of design of the gold that be like Ban, mould design, associated design, spare parts a group of things with common features, user defines the expert such as the design to design knowledge oneself, conduce to the three-dimensional model time that reduces a product, raise the efficiency of numerical control process designing and validity thereby. 5.
The development company of program of special postposition processing is put in the diversity of numerical control system commonly, wait like FANUC, SIMENSE, HEIDENHANE, system of each numerical control has an advantage each but each other is incompatible, accomplish very hard unified. Development company has the aftertreatment program of system of numerical control machine tool, on the foundation that can handle in program of general numerical control, from the machine tool configuration, program outputs commutation of format, coordinate to wait for a respect, have special development to its by the technical engineer that has software development and CNC Machining experience, when ensuring the machine tool in same kind undertakes machining, in share same knife below the circumstance of orbit, can output the program code that machine tool of corresponding numerical control processes. 6.
Design CNC Machining of reasonable cutting tool contrail to reflect the fast, high quality in cutting tool contrail finally to be designed, measure very big case to fall in eliminate of mould semifinished product especially more outstanding. Traditional method is to use commonly establish milling cutter to undertake rough machining, use ball head knife to have semifinishing machining and precision work. When rough machining stress begs efficient and fast platoon to measure, make full use of common device and union of numerical control equipment undertake. Making the level of industry pattern benchwork should consider when finish machining, choose reasonable cutting tool and step pitch, too big or cutting tool and step pitch are too small the treatment efficiency that goes against a product and production cost. Numerical control to program should combine material and mental allowance to come the cutting parameter that scientific and integrated consideration machines, it is a target in order to wait for bulk gearshift cutting and high speed cutting, build the warehouse of cutting craft parameter that develops cutting tool of commonly used material. 3, buy and use the play that decided this equipment potential greatly of type selecting of numerical control equipment and equipment of functional development numerical control. A lot of enterprises are mixed in equipment type selecting after buying, a few problems exist in use respect, wait for a respect like the journey of equipment, precision, function, latent capacity that can develop. Especially high speed of face of numerical control equipment, nice way develops, must consider software of integrated cost, CAM, experience when buying high speed machine tool accumulate with applied level. The gearshift that processes data hard to the tradition or gravitational cutting, must consider sex of steel of main shaft knife handle, choose large number as far as possible, be like the milling knife handle of BT50, what should consider machine tool function at the same time is patulous. On the other hand, in accessory of the development of equipment itself function and potential, machine tool, if the application of angle milling head comes,enlarge the applied limits of the machine tool. The development of function of the type selecting that is aimed at numerical control equipment and machine tool is used, can begin a few necessary works from the following respects. 1.
High school is cheap the collocation of numerical control equipment because the price of numerical control equipment is relatively high, enterprise but the actual condition according to oneself, be in inchoate when the application that has CNC Machining technology, choose transform numerical control equipment to undertake technical application invests, after gaining certain applied experience. Again the treatment characteristic according to the product, if material status, type, precision, batch, cycle asks to wait, configuration is proper in equipment of high-grade numerical control. 2.
Of equipment check and accept machine tool of a lot of numerical control bigger error appears below the circumstance that its compensate precision to be machined in high speed, or the rate that main shaft runs moves for long hard, because the phenomenon of high temperature burn down happens,bring about main shaft. When undertaking equipment is checked and accept, those who divide a country outside checking and accept a standard, product of oneself of OK and additional business machines the check of the requirement to accept a condition. 3.
Equipment function develops what the development of equipment function involves numerical control system to master degree, what cutting tool reachs workpiece material and cutting parameter is reasonable match. For example, vertical CNC Milling installs angle milling head to undertake horizontal is machined, CNC Milling undertakes boring hole, attack thread machining, the fixed loop that CNC Turning machines, the report of machine tool of cut of numerical control line and electric spark machine tool machines the logical choice of parameter to wait.
