Study on Software Reliability of Numerical Control System

Abstract:

With the rapid development of electronic components manufacturing technology and the application of reliability technology, the hardware reliability of the CNC system and servo drive system has been greatly improved. Currently, the performance and functionality of CNC system, which achieved gradually by the software instead of hardware, is becoming increasingly complex. However, very few researches on the reliability of CNC system software was presented. In this paper, the basic conceptions and important of CNC software reliability were discussed, and comparative analysis on the research status at domestic and abroad were studied from the view of theoretical research and engineering practice. Meanwhile, the paper collected field failure data on 30 CNC systems in six months, and reliability analysis was made based on the data.
