Description

technical field [0001] The invention belongs to the technical field of robot machining measurement and detection, and more specifically relates to a three-dimensional non-contact measurement device and method for blade grinding and polishing. Background technique [0002] Blades are widely used in the industrial field, and play an important role in gas turbines, aerospace, wind power and steam turbines, and are the most critical components. However, in actual situations, the surface accuracy, geometric contour shape and quality of the machined blade greatly affect the service life, work efficiency and performance of the overall equipment. Therefore, in the process of blade grinding and polishing, it is very important to obtain the real-time machining allowance of the grinding and polishing blade and to detect and measure the surface accuracy, surface quality and geometric contour accuracy of the grinding and polishing blade. [0003] In most cases, a mechanical contact thre...
