UG electrode in the mold of NC programming Ministry engaged in product and mold design. 3 Jiang Feiyue: UG electrodes in a cross with NC programming application 3NC sudden UnigraphicalsCAM 3.1 Program for NC software development process and environment of operation step into the Manufacture and clsf tool path generation post-processing files generated G code 3.2 Determination of NC tool path in the determination of the tool path is a very critical work, it must meet the cutting tool path line spacing and a reasonable distribution step, the error distribution and other requirements, it would be compiled by the NC program as short as possible to shorten processing time, but also to get a good surface quality. Implementation of tool path interpolation by the NC machine tools by function and the programmer decided to feed path chosen, the tool should normally be the longest straight line along the arc or direction, to reduce the interpolation point and the tool program pause; determine the tool path must also satisfy the requirements of surface roughness, CNC machining of parts of the surface roughness height of the main factors is the processing of residual Rt, as shown in Figure 5, Rt theoretical values calculated by the following formula: Rt = LV (8Re * coscO Figure 5,Moncler jacken, tool path simulation is not difficult to find, if a Z directly in the electrode groove LNUP2206 model (see Figure 4) to generate the tool path, then 55. and 35. the direction of the surface scallop height not the same as the processing, processing that the surface roughness of different, and to increase the number of interpolation points so that the program has become lengthy,ugg stivali, the program file is approximately 2918KB, is clearly unreasonable; If 55. the direction of tooth model (Figure 2) and 35. the direction of tooth model (Figure 3),stivali ugg, respectively, along the direction of tooth tool path generation, then it will solve all the problems mentioned above, the processing parameters in the same conditions, the generated file is 401KB, greatly reduces the processing time. 4 Conclusions NC The key to the preparation of NC program, which directly affect the processing efficiency and the quality of the workpiece,Moncler online, the process in specific programming note the following points: 1, according to the shape of the workpiece characteristics, a reasonable processing model, you can only build a model can build multiple models, but must ensure that the result after processing the same. 2, Unigraphicsmill - contour processing module provides a variety of driving methods (drivemethod), must be based on the geometry of the workpiece to select a different feature-driven approach, respectively, to generate reasonable tool path. 3, in the workpiece within the allowable error, try using a large tolerance values in order to reduce the number of interpolation points and procedures for length. 4, try using a large radius tooling ball, but the radius can not exceed concave parts of the smallest radius, the processing parameters in the same conditions, the large radius of the tool workpiece surface roughness less.
