Abstract: A five-axis linkage synchronous tool path interpolation method and system, which utilizes the strict proportional coefficient relationship between points, control points and parameters on the first-order derivative curve of the spline curve, more accurate tool axis path curve interpolation points from the parameters of the tool tip path curve are calculated. There is no need to calculate the tool axis path curve interpolation points according to interval synchronization. It is not affected by the shape consistency of the tool tip path curve and the tool axis path curve.

Abstract: A time optimal speed planning method and system based on constraint classification. The method comprises: reading path information and carrying out curve fitting to obtain a path curve; sampling the path curve, and considering static constraint to obtain a static upper bound value of a speed curve; considering dynamic constraint, and combining the static upper bound value of the speed curve to construct a time optimal speed model; carrying out convex transformation on the time optimal speed model to obtain a convex model; and solving the convex model based on a quadratic sequence planning method to obtain a final speed curve. The system comprises: a path curve module, a static constraint module, a dynamic constraint module, a model transformation module and a solving module.
