A Control Algorithm Based on Constant Linear Velocity Grinding of Edge Grinding Machine

Abstract

The invention discloses a control algorithm based on constant-linear speed grinding of an edge grinding machine. Firstly, track planning is conducted on the outer contour of a tableware plate, an outer contour curve is dispersed, and discrete point coordinate data are acquired; then, the grinding wheel feed speed Vx of each discrete point and the rotation tangential speed Vy of each discrete point are calculated, a program in a machine code G is written according to the grinding wheel feed speeds and the rotation tangential speeds, and through PID adjustment and control, constant-linear speed and constant-moment grinding is achieved. The PID algorithm is adopted to guarantee that a grinding wheel grinds the edge in a constant-moment mode. According to the control algorithm, outer contour calculation of the tableware plate is conducted, the code G is generated and used for controlling a feed shaft of the grinding wheel and a rotation shaft of the tableware plate to achieve two-shaft linkage, and constant-linear speed edge grinding is guaranteed. The control algorithm has the advantages that high adaptivity, high grinding precision and dynamic response are achieved and can be suitable for complex contour edges, and the grinding effect is good.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control algorithm based on constant linear speed grinding of an edger. Background technique [0002] At present, edging machines are mainly divided into two categories: manual edging machines and automatic edging machines. The traditional automatic edging machine, also known as the imitation shape machine, controls the shape of the ground product by profiling and uses the product template for positioning. However, every time a cutlery tray is ground by this edging machine, a template needs to be made for positioning, and the production cost is high and the efficiency is low. With the rapid development of rubber, plastic and other industrial economies, the scope of application of edging machines has been further expanded, and it has begun to be applied to the edging process of plastic tableware trays, and is continuously applicable to the processing of tableware trays...

AI Technical Summary

Problems solved by technology

However, for cutlery trays with a large aspect ratio or many sharp corners, it is difficult to achieve fast and timely tracking at the corners, resulting in uneven or insufficient edging, so this solution is difficult to meet complex and diverse tableware with special-shaped edges Disk edging requirements
