Abstract

The invention relates to a method for calculating grinding force. The method comprises the following steps: S1, calculating a relational expression of a normal force and a tangential force of a grinding force of a single abrasive particle when friction is not considered; S2, calculating a normal force calculation formula and a tangential force calculation formula of the polishing force in unit area; S3, calculating an integral calculation formula of normal grinding force in the radial direction of the grinding wheel, tangential grinding force in the tangential direction of the grinding wheel and axial grinding force in the rotation axis direction of the grinding wheel under the actual working condition according to the integral principle; S4, adopting an experimental test method to calculate constants in the formula in the step S3; and S5, calculating the grinding force of casting floating grinding through the integral calculation formula obtained in the step S4. Compared with the prior art, the casting floating polishing force calculation method solves the problem of casting floating polishing polishing force calculation through casting floating polishing mechanism research and discrete algorithm research, and provides technical support for casting floating polishing.

Description

technical field [0001] The invention belongs to the technical field of casting grinding, and in particular relates to a calculation method of grinding force. Background technique [0002] Casting grinding is to clean and repair the flashes and burrs that appear on the casting. The deviation or inconsistency of castings is the natural attribute of casting production. Therefore, floating grinding technology is vigorously promoted in casting grinding, and the inconsistency deviation of castings can be absorbed by floating to improve the grinding quality. Grinding force is an important parameter in floating grinding of castings. The study of grinding force is mainly to understand some basic conditions of the grinding process, which is the basis of workstation design and improvement, and the main problem of grinding research. Grinding force is one of the most important parameters in grinding. [0003] For the calculation of grinding force, we calculate with the help of grindin...
