Application of COMERO Data Collecting in Quality Management System

Exact and real-time collection of quality data from manufacturing process is the most important step in Quality Management System. It is the foundation of cumulating, analyzing and effectively controlling the process’s quality. As an advanced and exact metrical instrument, 3-degree Coordinate Measuring Machining (CMM) has been widely used in machinery manufacturing industry. However, it could only use text file to record the measuring result, which can not be integrated with the Quality Management System. This paper introduces appropriative interface software, which can automatically read the measurement data from 3-degree CMM’s RTF file and can automatically transfer the certain data to database and then let Quality Management System directly transfer the measurement result in order to analyze the correlative accessory’s quality. This analysis is useful to understand the characteristic of random error system, the trend of error, the order of error distributing and the reasons for error and also form the quality report and early warning information for quality control. Meanwhile, information’s automatically transmission can obviously improve working efficiency and effectively avoid the artificial errors. Heterogeneous Data’s conversion is the key point of system integration. This paper comprehensively analysis the expression mode of every dimension and error in the measurement text files mentioned above, and then applies certain program. In order to understand the meaning of relevant data, key words are needed. Using character string in the measurement files, which match the regular expression and the method of exhaustion, we could get the key words. Then the data, which quality management system needs, is formed by transferring data types with homonymous matching and written into the database. In order to achieve the information’s automatically transition, this paper also studies the data synchronization mechanism and ensure the measurement data can be synchronously updated in the Quality Management System by setting the trigger rule.
