Single-row Disjoint Stochastic Machining Path Planning Method for Arbitrary Boundary Optical Components

Abstract

The invention provides a method for generating a single-line disjoint random path for arbitrary boundary optical processing, which includes: defining a set of path points, adjacent points and non-path points, and the elements in the set are the coordinates of each point. A random sampling is performed on the set of adjacent points. If at least one sampling result satisfies the condition (feasible point) for joining the set of path points, it is added to the set of path points and taken out from the set of adjacent points and non-path points; if there is no If a sampling result satisfies the condition of adding to the path point set, a second random sampling is performed on the adjacent point set. If at least one sampling result satisfies the condition of a transformable point, it is transformed. The path point elements between are returned to the adjacent point set and the non-path point set, and then the transformable points are added to the path point set. Random sampling is repeated twice until the set of adjacent points is empty, and a single-row disjoint eight-way random path adapting to any boundary can be obtained.

Description

technical field [0001] The invention belongs to the field of advanced optical manufacturing and detection, and mainly relates to a small tool processing random path planning method used in the computer-controlled small tool surface forming process. Background technique [0002] In optical processing, the surface shape error data of the optical element surface after previous processing can usually be obtained according to various measurement methods. By planning a certain number and arrangement of dwell points on the component surface, the dwell time distribution corresponding to the dwell points can be calculated. Usually the dwell points are arranged in a uniform grid to ensure the reliability of the conversion between dwell time and dwell speed. The processing path is a connection method to connect these dwell points in series. Reasonable planning of the processing path can improve the processing quality and processing efficiency. The current mainstream processing paths ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problem that the existing grating path, spiral path and pseudo-random path are difficult to use a single path to walk through the full aperture of any boundary optical element, or can walk through the full aperture of any boundary optical element but the paths intersect

Improving the traditional grating, spiral and other regular processing paths will bring obvious intermediate frequency errors due to path residuals, overcoming the problem that traditional regular processing paths or pseudo-random paths are difficult to adapt to arbitrary boundary optical elements
