Machinery Condition Surveillance System.
Abstract
Machine tools under heavy production demands are likely candidates to experience mechanical malfunctions such as spindle imbalance, worn shafts and bearings, inadequate/degraded cutting tool coolant, and gearbox overheating. Similarly, it is not uncommon to find moderate vibration levels present in machining processes contributing to dimensional/surface finish inferiority. These conditions result in lost manufacturing time and the attendant expense. A pilot program was instituted offering continuous monitoring of a three-axis machining center. A Machinery Condition Surveillance System (MCSS) measures and analyzes multiparameter signals generated from non-cutting (free-state) and dynamic metal removal activity. The MCSS is comprised of three dedicated subsystem units: a signal processor, an engineering analysis computer, and a DNC DEC/VAX computer. The integrated system performs automatic collection, processing, and storage of data, and various analysis functions. Using statistical methods yields early warning identification and alert for defective machinery components.
