Processing method of inner surface

Abstract

The invention discloses a processing method of an inner surface and belongs to the field of machining. The processing method comprises: setting a cutting sample on a workbench of a numerical control boring-milling apparatus; processing a test inner surface on the cutting sample according to theoretical parameters, test cutting depth and test cutting length, wherein the theoretical parameters are parameters that allows an inner surface to be processed theoretically on a workpiece under processing, and the theoretical parameters include theoretical tool speed and theoretical feeding speed; measuring actual parameters of the test inner surface; comparing the actual parameters with required parameters; if deviation requirements are met, processing an inner surface on the workpiece under processing according to the theoretical parameters, workpiece depth and workpiece length; if the deviation requirements are not met, correcting the theoretical parameters according to the actual parametersand the required parameters to obtain corrected parameters; processing an inner surface on the workpiece under processing according to the theoretical parameters, the corrected parameters, the workpiece depth and the workpiece length. The processing method provides improved processing precision for an inner surface.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method of an inner curved surface. Background technique [0002] The vane motor is a common hydraulic component. The inner surface of the shell is provided with multiple intervals and parallel arrangements of inner curved surfaces. The machining accuracy and surface roughness of the inner curved surface have a direct impact on the working efficiency and service life of the motor. Conventional CNC Boring and milling equipment cannot meet the demand. [0003] In order to solve the above problems, curve grinding machines are usually used to process the inner surface, but for super large displacement vane motors, the size of the inner surface is very large, which has exceeded the maximum size that can be processed by conventional curve grinding machines, so it is impossible to use conventional The curve grinder is used for finishing, and only a dedicated...
