The invention discloses a curved surface self-adaptive grinding and polishing method based on a two-degree-of-freedom force control grinding and polishing robot. The method comprises the steps that a surface image of a workpiece to be machined is acquired, and local curvature information is extracted; calculating a feed-forward compensation amount according to the local curvature information, and correcting a preset expected position and a preset expected speed based on the feed-forward compensation amount to obtain a corrected expected position and a corrected expected speed; on the basis of the position deviation between the corrected expected position and the actual position and the speed deviation between the corrected expected speed and the actual speed, inertial parameters and damping parameters of a position-based impedance model are adjusted in real time through a fuzzy adaptive algorithm; and generating a control instruction according to the adjusted impedance model, and driving the two-degree-of-freedom linear motion module to perform compensation motion. According to the method, through cooperation of curvature feedforward compensation and fuzzy variable impedance control, force control lag at the curvature sudden change position is reduced, and force control stability and machining consistency of complex curved surface grinding and polishing are improved.

This invention is a steel billet grinding process with a constant grinding wheel linear speed. First, the steel billet is automatically fed, positioned, and locked. A laser rangefinder detects the actual length of the steel billet and calibrates the grinding wheel to align with the billet's length center. Then, the grinding wheel is controlled to apply pressure and adhere to the steel billet, driving the billet to translate and complete the grinding of both sides. During the grinding stage at the billet's ends, the speed and pressure are automatically reduced to avoid over-grinding and sharpening at the ends. A trolley tilting mechanism rotates the billet 45° multiple times, cyclically grinding all sides and edges of the billet, using a repeated grinding method with decreasing feed depth to ensure grinding accuracy. Simultaneously, photoelectric switches on both sides of the grinding wheel monitor the wear on the outer circumference of the grinding wheel in real time, dynamically adjusting the grinding wheel motor speed to maintain a constant grinding linear speed, and simultaneously calibrating the distance between the grinding wheel and the billet to stabilize the grinding pressure. This invention effectively ensures uniform overall grinding quality of the steel billet and improves the grinding accuracy and stability of the billet's sides and edges.
