The invention discloses an eccentricity extraction method for a micro-milling cutter. The method comprises the following steps: 1) obtaining holder outer contour play eccentricity data of a micro-milling cutter through a laser displacement sensor I, and obtaining bottom outer contour play eccentricity data of the milling cutter through a laser displacement sensor II; 2) collecting the holder outer contour play eccentricity data of the micro-milling cutter and the bottom outer contour play eccentricity data of the micro-milling cutter within one cycle; and 3) extracting the eccentricity of the micro-milling cutter according to the formula shown in the specification, wherein gamma0 is the eccentric angle of the cutter, R0 is the eccentric distance of the cutter, R is the radius of the cutter, and Delta h, gamma1 and gamma2 are obtained through step 2). The method disclosed by the invention is simple and convenient to operate.
Description
technical field [0001] The invention belongs to the technical field of micro-milling, and in particular relates to a method for extracting eccentricity of a micro-milling tool. Background technique [0002] Nowadays, the demand for high-precision micro-components is increasing rapidly in many fields, especially in the fields of aerospace, biomedicine, electronic communication and environmental protection technology. Micro-milling processing technology has its unique advantages in processing complex micro-components, because micro-milling processing technology appeared relatively late, and compared with macro-milling processing technology, it has its unique size effect and other characteristics. The research on the machining mechanism of the milling process mainly includes the modeling of the milling force and the modeling of the surface topography. At present, the research on the machining mechanism of the micro-milling is still in the development stage. In the research pro...
