1、中文 1839 字 Moulds CAD/CAM Based on SolidWorks and MasterCAM Abstract: SolidWorks is a famous software for moulds design， MasterCAM is a popular software of NC machining. This paper aims at taking full advantages of this two kinds of software to design and manufacture mould. Through the example of des
2、igning and manufacturing of cell phone cover mould， expound the method and technological process of NC machining by using this two kinds of software. Keywords: SolidWorks,MasterCAM,CAD/CAM,NC Machining 1 SolidWorks and MasterCAM introduce The SolidWorks software belongs to the end three dimensional
3、CAD software, is Dassault System Corporation serves under somebodys banner the SolidWorks subsidiary company the product, the software the most major characteristic is easy to study easily to use, easy to grasp, is low to hardwares request. Moreover, around the world several hundred companies develo
4、ped the specialized project application system based on SolidWork* to integrate SolidWorks as the plug-in unit in the software contact surface, including mold design, manufacture, analysis, product demonstration, data conversion and so on, caused it to become has the practical application solution s
5、oftware system, but must realize the application in the project to need other modules the support. MasterCAM American NC Software Corporation develops the development the CAD/CAM system software, as a result of remarkable processing the function, has the numerous faithful users in the world, pan-is
6、applied in machine domains and so on weapon, aviation, shipbuilding, mold. However the MasterCAM design (CAD) function is relatively weak, when carries on the complex surface modeling one is quite difficult, but this is precisely the SolidWorks superiority is. This article was the MasterCAM software
7、 has provided DXF, I(ES, CADL, VDA, STL, PA- RASLD, DWG and so on standard graph transformation connection, may graph transformation cost systems graphic file which produced other CAD software, realized graphic file sharing. Establishes the model postselection reasonable processing way, using the Ma
8、sterCAM turning, the milling and the line cutting module can establish highly effective the each numerical control processing program, facilitates realizes the graph carving function quickly. therefore carries on the CAD design using SolidWorks, unifies MasterCAM to carry on the numerical control pr
9、ocessing, becomes the current mold enterprise priority selection CAD/CAM way Below has take the handset cover mold as an example, introduced that SolidWorks unifies MasterCAM9. 0 in mold design and processing aspect application. 2 Based on the SolidWorks handset cover mold designs The SolidWorks sof
10、tware has the very strong modelling function, uses its stretch, the excision, the drill hole, the bevel edge, to pull out orders and so on shell, curve surface to be possible to complete each type the components design. 2. 1 primitive design model By the hand canopy example, uses the SolidWorks soft
11、ware choice components, chooses the schematic diagram first and draws up the schematic diagram, carries on the size restraint and the geometry relations restraint, then carries on production three dimensional block diagrams and so on stretch, excision, drill hole, bevel edge. 2. 2 Handset outer cove
12、ring manufacture processes (1) SolidWorks handset outer covering manufacture Like above turns on the components cartography frame, the choice “the foresight”, the insertion “the reduced plane 1,” in “the frame inputs in “the equal-space distance 10”, establishes the reduced plane 1, like Figure 1. F
13、igure 1 the reduced plane establishes On draws up the ellipse graph in “the head-on view”, the choice “the tool/schematic diagram” the plan “tool/cutting out” the straight line carries on cutting out, the size establishment to the ellipse, like Figure 2. On draws up 1 the same graph in the reduced p
14、lane”, the choice “the insertion/lug boss substrate/lofting”, springs the lofting dialog box, in the frame chooses “the schematic diagram separately in “the outline” 1” and “the schematic diagram 2”, selects on the graph the superficial sideline to its round angle, the radius is 10 mm, like Figure 3. The choice “the tool/schematic diagram plan entity/writing” on the graph the superficial plan writing, then the click “stretches the lug boss/substrate” the button, depth 1mm, effect like chart 4.
