The invention discloses a high-precision numerical control machining method for the outer plate mold surface of a magnesium-aluminum alloy automobile cover, which solves the precision caused by multiple factors such as the axial clearance of the machine tool, the deceleration of the machine tool spanning, the force point of the tool, the tool wear, the cutting method and the temperature. Reduced and typical feature retention incomplete technical issues. The invention includes profile technology analysis, profile processing subdivision, island filling and subdivision, processing subdivision sorting, processing mode conversion, programming, and grinding tool profile ultra-fine processing. The invention provides the premise for completing the die cold stamping forming of the outer plate of the magnesium-aluminum alloy automobile cover, greatly reduces the errors and distortions caused by the problems of the machine tool processing spanning deceleration, the machine tool axial clearance and the like, and ensures the processing accuracy; the invention improves the The machining accuracy is improved, and the machining distortion caused by tool wear is reduced; the present invention realizes the manufacture of products with high precision and high feature fidelity.
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...
