Abstract

The invention provides a carton cutting method based on time division method cutting knife tangent following control. The carton cutting method comprises the following steps that step one, an upper computer issues a PLT file to a controller; step two, the controller reads PLT file graphic information, wherein the PLT file graphic information is composed of multiple straight lines and circular curves; and step three, whether the current cutting line is a straight line or a circular curve is judged, 3.1) if the current cutting line is the straight line, cutting is performed according to the existing method; and 3.2) if the current cutting line is the circular curve, a cutting knife is rotated to a position tangent with a circular start point firstly, the start angle of the cutting knife is determined, a circular curve tangent following motion model is determined, and the feed amount of an X-axis and Y-axis knife rotation shaft of each interpolation cycle is determined by adopting a circular time division method so that tangent following of the cutting knife can be realized. According to the carton cutting method based on time division method cutting knife tangent following control, the carton cutting method can enhance control precision and has great stability.

Description

technical field [0001] The patent of the invention belongs to the technical field of motion control, especially the multi-axis control cutting equipment for tangentially following the cutter. Background technique [0002] With the development of science and technology, CNC equipment has been widely used in cartons, clothing, leather, and other fields. The general CNC system also has the interpolation function of straight line and arc, which can realize the interpolation function of contour. The carton cutting machine is used to cut the cardboard into specific graphics, and fold the cut cardboard into the required carton type. The carton cutting machine belongs to the field of cutting bed. [0003] In the process of carton production, first, according to the technical requirements of the product, the required cutting graphics are designed on CAD and other drawing software, and the PLT file is generated. The upper computer sends the graphics file to the controller, and the con...
