Abstract

The invention provides an electronic cam curve generation method and system, a computer storage medium and a terminal. The electronic cam curve generation method comprises: receiving N control points; enabling the control point to be a reference point located on the curve of the electronic cam; enabling n to represent the number of the control points and to be greater than or equal to 2; extracting an ith control point and an (i + 1) th control point, and generating a piecewise polynomial curve passing through the ith control point and the (i + 1) th control point, wherein i is an extraction serial number of the control point and is greater than or equal to 1; and when traversing to the last control point, sequentially combining the generated piecewise polynomial curves into an electronic cam curve, and storing the electronic cam curve as an electronic cam file. The cam curve generated by using the seven-degree polynomial can enable the acceleration of the motor to be continuous everywhere and the jerk to be guided everywhere in the execution process, so that the mechanical soft impact is eliminated, and the service life of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cam software, and relates to a generation method and system, in particular to a generation method, system, computer storage medium and terminal of an electronic cam curve. Background technique [0002] With the improvement of the current level of production automation in China, more and more factory automated production lines have begun to replace traditional manual operations, which involves various fields such as textiles, printing, cutting, and item packaging. [0003] In these operations, it is often necessary to ensure strict synchronization of positions between multiple actuators. For example, the blade of the paper cutter and the conveyor belt need to keep the cutting process relatively stationary laterally and move to the next cutting point at the same distance. [0004] Most of the existing technical solutions are to connect the driven actuators through mechanical cams, tappets and other transmis...
