Abstract

The invention belongs to the technical field of intelligent grinding and polishing manufacturing, in particular to a high-order cutting contact enveloping grinding and polishing method and applicationthereof. The method comprises the steps of 1, identifying curve faces of a workpiece and selecting a convex curved face area; 2, dividing the convex curved face area to obtain multiple sector cylinders and the machining poses, the enveloping angles [alpha] and the grinding and polishing quantities of the sector cylinders; 3, enabling one of the sector cylinders to make contact with a sanding belt, and adjusting the corresponding machining pose of the sector cylinder to make the angle of enveloping segmental arc between the workpiece and the sanding belt be equal to the enveloping angle [alpha]; 4, measuring the contact force of the sanding belt and the sector cylinders in real time until the removal amount of the sector cylinder is equal to the grinding and polishing quantity; and 5, repeating the step 3 and the step 4 until each sector cylinder is adjusted in the same way to complete the grinding and polishing of the workpiece. According to the method and the application thereof, theworkpiece is ground and polished in high-order cutting contact enveloping manner, and the machining is high in precision, good in quality, and high in efficiency.

Description

technical field

[0001] The invention belongs to the technical field of intelligent grinding and polishing, and more specifically relates to a high-order tangential contact enveloping grinding and polishing method and its application. Background technique

[0002] With the development of science and technology, complex surfaces are widely used in aerospace, automobile, ship and other fields. These surfaces cannot be composed of elementary analytical surfaces, and it is difficult to obtain accurate analytical solutions for free complex surfaces. Therefore, the finishing of complex surfaces is a manufacturing problem that needs to be solved urgently.

[0003] like figure 2 As shown, the first-order contact has a common tangent plane; the second-order contact has the same curvature; the third-order contact has the same curvature and curvature derivative. In the field of grinding processing, there is no contact order. Evaluation criteria Research on the planning of the tool pat...
