This application discloses a method and apparatus for water-guided laser curve processing based on curvature adaptive variable voltage amplitude-frequency, relating to the field of water-guided laser processing technology. It includes: collecting curvature radius data at various points along the water-guided laser processing path; establishing a control mapping model between the curvature radius and deflection voltage parameters based on the curvature radius data; wherein the deflection voltage parameters include voltage amplitude and driving frequency; using the curvature radius of the current processing point as input, obtaining a target voltage amplitude and target driving frequency that match the curve characteristics corresponding to the current curvature radius through the control mapping model; converting the target voltage amplitude and target driving frequency into driving signals and outputting them to the deflection electrode array to dynamically adjust the deflection voltage parameters and control the water beam to complete deflection scanning processing along a preset curve trajectory. This solves the problems of mismatch between deflection response and curve geometry, large trajectory tracking errors, and poor surface quality consistency in existing curve processing technologies.
