Abstract

The invention discloses a local fairing transition method and device between tracks, an apparatus and a storage medium, and the method comprises the steps of taking all i = 0, 1,... N, calculating and solving a distance e (i) with a p1 by using a distance formula, and if min {e(0), e(1),... e(N)} < epsilon, taking a new feasible solution; otherwise, re-obtaining j = j+1 by utilizing a test solution solving formula, if j is greater than cout, taking as a final solution, and otherwise, returning to re-execute the steps. By means of the local fairing transition method between the tracks, the fairing transition problem between straight lines, between straight lines and arcs and between arcs can be solved, errors are controllable, the machining path can be further faired, the machining efficiency is improved, and then the machining effect is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a local smooth transition method, device, equipment and storage medium between trajectories. Background technique [0002] At present, the input of the three-axis CNC system generally adopts straight lines and arcs. Because there is a corner between the straight line and the straight line, there is a sudden change in the centripetal force between the straight line and the arc, so if the straight line and the arc are directly processed, the speed or acceleration will not be smooth at the intersection of the straight line and the straight line, or the straight line and the arc. Affect processing efficiency and processing effect. For this reason, a large number of researchers have discussed the smoothing problem between straight lines, such as the global fitting smoothing method using A-splines, B-splines, C-splines or NURBS splines, using arcs, parabolas, Hermite Local ...
