Abstract:
In deep hole
drilling, the power consumption of the main spindle motor is a
good indirect reflection of the circumstances in the drilling
zone. In this paper, the changes in the patterns of the power
signals during normal and abnormal drilling processes are
experimentally investigated. The characteristic extraction
method and some problems associated with real time detection are
analyzed and discussed. A microcomputer based monitoring system
is established and the abnormal states detection in deep hole
drilling is initially realized.
