Embodiment 1
[0031] Embodiment 1, the high-precision numerical control processing method of the mold surface of the outer panel mold of the magnesium-aluminum alloy automobile panel, such as figure 1 As shown, it includes the following steps: Step 1: Surface process analysis, Step 2: Surface processing partition, Step 3: Island area filling and subdivision, Step 4: Processing partition sorting, Step 5: Processing method conversion, Step 6: Programming, Step 7: Ultra-fine processing of the mold surface.
[0032] The first step includes conducting a comprehensive analysis of the mold according to the functional area and shape structure of the mold surface, sorting out the surface characteristics of the mold surface: undulation angle, surface curvature, minimum R angle value, small-area groove, and analyzing the mold shape at the same time. The functional level of the surface. Match the function level with the mold area to fully control the surface information of the mold, and do a comprehen...

The invention discloses a molded surface high-precision numerical control machining method for magnesium aluminum alloy vehicle covering part outer plate molds, and solves the technical problems of reduced precision and incomplete retaining of typical characteristics caused by such multiple factors as the machine tool axial gap, the machine tool span speed reduction, the cutter exerting point, thecutter wear, the cutter feeding mode and the temperature. The method comprises the steps of molded surface process analysis, molded surface machining partition, islet area filling and subdivision, machining partition sorting, machining mode change, programming and grinder molded surface ultrafine machining. The method provides preconditions for mold cold punching molding of magnesium aluminum alloy vehicle covering part outer plates, greatly reduces errors and distortion caused by such problems as machine tool machining span speed reduction and machine tool axial gaps, guarantees the machining precision, improves the machining precision, reduces the machining distortion caused by the cutter wear, and achieves high-precision and high-characteristic-fidelity manufacturing of products.
Description
technical field [0001] The invention relates to the technical field of mold surface processing, in particular to a high-precision numerical control processing method for the mold surface of an outer panel mold of a magnesium-aluminum alloy automobile cover. Background technique [0002] The main material of automobile panels in the early stage is steel plate, but along with people's continuous pursuit of high-quality automobiles, automobile panels of new materials continue to emerge, mainly to meet the needs of high-quality vehicles and the needs of lightweight vehicles, energy-saving emission reduction and long battery life. At present, the automobile panel material that can perfectly combine the two is magnesium-aluminum plate, which has a series of advantages such as light weight, high strength, and wear and corrosion resistance. However, due to its low elongation rate, material viscosity and deformation uncertainty For other reasons, the mold forming of the outer panel o...
