Abstract

The invention discloses an interpolation control method. The method comprises the following steps: for the jth interpolation point of a k-degree B-spline curve, obtaining curvature parameters of the (j-1)th interpolation point by utilizing a basis function of the k-degree B-spline curve and an interpolation independent variable of the (j-1)th interpolation point; calculating interpolation speed ofthe jth interpolation point according to the curvature parameters and speed control parameters, wherein the speed control parameters comprise preset interpolation accuracy and / or angular velocity threshold; and carrying out interpolation of the jth period according to the interpolation speed of the jth interpolation point. By setting the speed control parameters, the interpolation speed of the jth interpolation point can be obtained with the curvature parameters of the (j-1)th interpolation point and the speed control parameters being combined, so that interpolation speed be adjusted in realtime based on change of the curvature parameters, and the obtained interpolation speed can meet speed control requirements, such as requirements of precision and / angular velocity; and interpolation quality and interpolation efficiency are improved.

Description

technical field [0001] The invention relates to the field of numerical control systems, in particular to an interpolation control method and device, computer equipment and a readable storage medium. Background technique [0002] The core of the CNC field is the CNC interpolation technology. China is in the period of industrial transformation. The rapid growth of the automobile, steel, machinery, electronics and other industries constitutes a huge demand for CNC machine tools, but its core technology, the interpolation technology, still exists. Many questions. [0003] At present, the existing interpolation methods in the field of numerical control cannot meet the actual interpolation needs, resulting in poor quality and low efficiency. Contents of the invention [0004] The main purpose of the present invention is to provide an interpolation control method and device, computer equipment and readable storage medium, which can solve the problems in the prior art that cannot...
