Abstract
The invention discloses a method for obtaining high-efficiency low-stress grinding process parameters of ultra-high-strength steel. The method comprises the following steps of: step 1, establishing a surface integrity grinding process parameter domain of the ultra-high-strength steel, performing an orthogonal test, and establishing a relational expression of surface integrity grinding process parameters of the ultra-high-strength steel and surface integrity characteristics through the orthogonal test; step 2, establishing an objective function, performing linear treatment, and establishing constraint conditions for the relational expression of the grinding process parameter domain and the characteristics, which are established in the step 1; step 3, establishing a surface integrity high-efficiency low-stress grinding process parameter optimization model of the ultra-high-strength steel according to the objective function and the constraint conditions, which are established in the step 2, and performing solving to obtain the high-efficiency low-stress grinding process parameters of the ultra-high-strength steel; and step 4, verifying the grinding process parameters obtained in the step 3 to obtain the final high-efficiency low-stress grinding process parameters of the ultra-high-strength steel. Through the adoption of the method disclosed by the invention, during grinding of a ultra-high-strength steel component, residual stress on surfaces is small, and grinding efficiency is high.
Description
【Technical Field】 [0001] The invention belongs to the technical field of precision and ultra-precision grinding processing, and specifically relates to a method for obtaining high-efficiency low-stress grinding process parameters of ultra-high-strength steel. 【Background technique】 [0002] Ultra-high-strength steel has high strength and hardness, but also has good toughness and plasticity. From the point of view of mechanical characteristics, ultra-high-strength steel has a high yield stress and can withstand greater loads under the same deformation conditions. It can also absorb more energy. Aermet100 is a high-strength, high-toughness, high-alloy ultra-high-strength steel with excellent stress corrosion cracking resistance and fatigue resistance. Because of its excellent comprehensive mechanical properties, it is widely used in the manufacture of aircraft landing gears and gas turbines. Engine shafts and wheel bolts are important structural components in the aviation and aero...
