Design of band saw cutting load testing system.

Aiming at the requirement of cutting precision and rfficiency of metal band sawing machine, a sawing load detection system of band sawing machine was designed, a expert system intelligent recognition strategy based on rough set data analysis! RSDA) was proposed. Cutting vibration signal was real-time collected by this system, the eigenvalue which was extracted by signal proceesing part was stored in database of expert system, cutting load was recognized through the comparative analysis of diagnostic model. The results indicate that, the cutting load detection system has characteristics of high recognition rate and fast response, the detection precision can reach one thousandth of load testing range. This system can meet the needs of on-line identification of band saw cutting load. [ABSTRACT FROM AUTHOR]
