First, the basic work of networked CNC machining
The basic work of networked CNC machining is shown in Figure 1. It considers the bottom-level operations required for networked product processing, regardless of the physical factors involved in CNC machining, such as material flow, product data management, cutting force and vibration, wear and precision. Only in the networked environment to achieve the basic work of CNC machining, it is possible to conduct network research on other operations. The basic work mainly achieves the following objectives:
(1) Dynamically publish the product geometric shape on the Internet, so that users can browse to the design they need conveniently, quickly and accurately, and can modify it interactively.
(2) Realize the online optimization function of process parameters, and establish an optimization model with optimization and processing speed as the optimization target to determine the cutting amount.
(3) Automatically generate NC code and tool path according to the results of a and b, realize automatic generation of NC code and remote transmission for product processing.
(4) Apply virtual manufacturing technology and network to realize the simulation of NC machining process, and verify the correctness of NC code in different places......
(5) Perform on-site instance processing through the above work.
(6) If there is any doubt in the above links, they can negotiate with each other through the online communication module.
Second, the example
1. Network production of product geometry. Pro/E software is used to realize the 3D geometric shape of the milling products, embedded in the VRML browser form, and browse the WRL graphic files exported by Pro/E. In order to successfully implement web browsing of WRL files, the VRML browser VRM LZC or Cosmo Player must be installed. The product graphic web browsing page realized by the VRML2C browsing tool, which can perform the operations of panning, rotating, simulating the camera zooming and the like in the webpage by using the buttons of the surrounding.
2. Network production of the path of the knife. Use Pro/E Zhuang software to realize the tool path of product processing, then convert it into bitmap format, and use the image insertion method in webpage to realize web publishing and browsing of the tool path.
3. Network processing of NC processing. Use Pro/E software to implement 3D geometric simulation graphics for products and convert them into bitmap animations supported by the Web. Using the screen capture technology of the media, the product processing process in the CAM system under the Pro/E environment is captured, and the avi video file is formed, embedded in the set webpage, and the network browsing of the NC processing simulation is completed, which can be used for the online verification of the processing track. .
4. Online communication. Use the upload and download technology to complete online communication. When the user who is the client accesses the above-mentioned Web page, there will be a place that does not conform to his own design scheme, and communication is required in time. Users can instantly capture the CAD/CAM graphic web page, complete their own annotations or suggestions on the above, save the identified files according to their needs, and then transfer them online to complete the fast communication.
