Large Dual Drive Glass Cutting Machine Motion Error Analysis And Control

Benefit from its good characteristics—reduces heat flow and soundproofing--insulating glass now has been widely used in architectures, vehicles and track traffics. Based on the process flow, the raw glass sheet need to be filmed, cut, edged and cleaned, then becomes a piece of insulate glass finally. Among all these, cutting machine locates at the second step of processing technical. Its precision significantly influences the following steps and the quality of the final products.This paper firstly introduces the mechanical structure of Glass Cutting Machine and its control method. Secondly analyze its error sources, including machining, Parts assembly, Servo parameter, Inverter parameter settings, Cutting procedure and environment impact of the machine. Now, the design and installation of electrical controls for Glass cutting machine have been finished. Some mechanism parts of the machine are being processed and waiting for being assembled. So an experiment platform was build based on that control mode and mechanism structure to simulate the movement on x-axis (two servo system) and y-axis of cutting machine. This simulation experiment specifically focuses on the cutting experiment table, consists of guideway, Servo drive system, optical grating and Encoder system. A movement error test was conducted after connection work and Servo debugging.This experiment has to be done after 1-2 hours normal running. Collecting experimental tolerance data using Renishaw laser interferometer, calculate a compensation value after data analysis, and then input this value into our experiment system to compare with. Repeat this process until composite error get into an acceptable range.Finally the cause of error position could be found and the method will be provided to reduce the general error through analysis.
