Prediction of surface product quality and operation reliability of grinding machines

Abstract

High quality products require modern and precise production machines, technologies and quality equipment of industrial metrology. Research paper discusses the possibility of vibration detection at production machines because of process conditions changes. Furthermore, paper also provides a methodology for assessment of vibration amplitude using non-contact laser interferometer, which uses Michelson principle for evaluation. Paper also provides information about a method of vibration amplitude evaluation by contact method using a piezoelectric vibration sensor connected to Balantron 2001 device. The effect of technological conditions on the quality of functional areas expressed by the arithmetic average roughness is experimentally and statistically determined. Experimental study also evaluates the influence of technological conditions during surface grinding on the amplitude of vibration of grinding spindle and provides a correlation between the vibration amplitude of grinding machine and product quality. Moreover, the change of vibration amplitude during three years of production is observed and production capabilities and accuracy of the machine during five years of manufacturing were predicted. © 2014.
