Abstract

The present invention provides an interpolation control method, a device and a readable storage medium, which relate to the technical field of digital control, wherein the interpolation control method, applied to a numerical control system, includes: acquiring a sequence of control points, a first rough interpolation period and the first fine interpolation period; integerize the first fine interpolation period to obtain the second fine interpolation period; determine the second coarse interpolation period; according to the control point sequence and the second rough interpolation period Periodically determine a first curve equation; wherein, the first curve equation takes time as a variable and an interpolation point as a dependent variable; determines the interpolation point corresponding to the interpolation time according to the first curve equation; wherein, the interpolation The interpolation time is a natural number multiple of the second fine interpolation period. In the embodiment of the present invention, by integerizing the fine interpolation period, in the process of determining the interpolation point according to the first curve equation and the interpolation time, the operation of decimals or fractions is reduced, thereby reducing the complexity of interpolation control , which improves the interpolation efficiency.

Description

technical field [0001] The present invention relates to the technical field of digital control, and in particular, to an interpolation control method, device and readable storage medium. Background technique [0002] Interpolation generally refers to the process in which the CNC system of the machine tool determines the tool movement trajectory according to a certain method. The interpolation process generally uses the curve equation of the interpolation point with respect to time to obtain the interpolation points corresponding to different interpolation times, so as to realize the densification of the data points of the tool motion path. In the prior art, there are usually time values ​​with decimals or fractions in the set of interpolation time. When these time values ​​are calculated multiple times, the operation process will be complicated, which will lead to low operating efficiency. technical problem.
