Abstract

The invention provides a method and device for determining the target speed of S-shaped speed planning, which belongs to the technical field of numerical control machining. The method comprises steps of acquiring cutter motion parameters, determining a target speed equation about the target speed according to the cutter motion parameters, solving the target speed equation by adopting a Lagrange interpolation method to obtain a target speed, and controlling the cutter to move according to the target speed. According to the method, a plurality of target function equations related to the target speed are obtained by analyzing the numerical relationship of each motion parameter under different values, and a method for solving the target function parameters by using the Lagrange interpolation method is provided for the target speed equation with the high-order term, the problem caused by complexity when a numerical value method represented by a bisection method and a Newton method is used for solving target function parameters is solved to a great extent, the real-time performance of the S-shaped speed planning process is improved, and the requirement for the hardware computing power of a numerical control machine tool is lowered.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, and more specifically relates to a method, a device, a computer program product and a computer-readable storage medium for determining a target speed of an S-shaped speed plan. Background technique [0002] The S-shaped speed change strategy is a speed control strategy that is widely used in the field of numerical control. Its biggest feature is that the acceleration is continuous during the speed change process, thereby reducing the soft impact caused by sudden acceleration changes, thereby improving the stability of the machine tool, and optimizing It is beneficial in terms of processing quality and improving the service life of machine tools. [0003] In order to make the control target move according to the required S-shaped speed change strategy, S-shaped speed planning is required. In the process of S-shaped speed planning, the target speed, that is, the maximum speed t...
