Space filling curve-based numerical control machining tool path generation method

Abstract

The invention provides a space filling curve-based numerical control machining tool path generation method, and the steps of: 1. performing regional division on a curved surface according to the shape of the curved surface and a path with the steepest gradient and determining the order of a two-dimensional region filling curve of each region according to residual height, and then generating the two-dimensional region filling curves of corresponding orders, and connecting the two-dimensional region filling curves of adjacent regions in an end-to-end manner to obtain a two-dimensional filling curve; and 2. mapping the two-dimensional filling curve to a space curved surface according to a mapping principle, thereby obtaining a numerical control machining tool path. The space filling curve-based numerical control machining tool path generation method provided by the invention uses the path with the steepest gradient to perform regional division on the curved surface, and then generates the two-dimensional filling curve, not only is the length of the whole tool path shortened, but the number of times of steering is reduced to about eighty percent of a previous number, and machining quality is better than most methods.
