A method, system, and storage medium for interpolating and connecting S-shaped velocity curves.
ActiveCN121900314BAchieve accurate interpolation compensationEliminate speed fluctuationsNumerical controlTime domainClassical mechanics
This invention relates to the field of CNC machining and motion control technology, specifically to a method, system, and storage medium for interpolation connection processing of S-shaped speed curves. This method addresses the speed fluctuations and uneven machining marks caused by the asynchronous connection points between segments and the interpolation cycle in existing global S-shaped speed planning by proposing a reverse extension compensation mechanism. The steps include: when entering a new curve segment for interpolation, if there is residual motion and the motion stage is continuous, the current motion stage is extended backward by one interpolation cycle in the time domain; by solving the displacement equation, the historical time point corresponding to the residual motion in the current stage is accurately calculated; and the system's time state is corrected accordingly, thereby achieving smooth and accurate connection between segments. This invention effectively eliminates the deviation between interpolation commands and speed planning, solves the speed fluctuation problem caused by toolpath deflection, makes the tool marks more uniform, and improves machining quality.

Method and device for supplementing feature points of a same-diameter pipeline intersecting line weld and electronic equipment
The application provides a characteristic point supplement method and device for the intersection line weld of the same-diameter pipeline, and electronic equipment. For two incoherent elliptical characteristic point sequences corresponding to the same-diameter pipeline, three-dimensional elliptical fitting is performed on the three-dimensional point cloud corresponding to each elliptical characteristic point sequence, and the intersection point of the fitted three-dimensional ellipse is determined. The intersection point is used as a connection reference, the curve trajectory of the three-dimensional ellipse is combined, and the supplement points are generated according to the density of the elliptical characteristic point sequence. Based on the supplement points, the intersection point and the elliptical characteristic point sequence, two complete characteristic point sets are obtained. Finally, the two complete characteristic point sets are combined to obtain a continuous and closed weld characteristic point set containing the intersection line weld of the same-diameter pipeline. The scheme can accurately locate the connection point position of the two cylindrical tangent regions of the same-diameter pipeline, provides a core reference for weld closure, and supplements the intersection line defect region based on the intersection point and the elliptical trajectory, thereby solving the defect that the weld cannot be closed in the prior art.
