To obtain the characteristic life of a chain tool magazine and automatic tool changer under normal working condition, a small-sample accelerated life test method was developed. The inverse power law model and small-sample virtual augmented theory was applied while taking vibration as the accelerated stress. The accelerated life test of the automatic tool changer was carried out under different ...

A tool remaining useful life prediction method based on a non-homogeneous Poisson process and Weibull proportional hazard model (WPHM) is proposed, taking into account the grinding repair of machine tools during operation. The intrinsic failure rate built according to data. WPHM established by collecting vibration information operation introducing covariates describe In combination with repair,...

Food is at the centre of efforts to combat climate change, reduce water stress, pollution, and conserve world’s wildlife. Assessing environmental performance food companies essential provide a comprehensive view production processes gain insight into improvement options, but such tool currently non-existent in literature. This study proposed based on life cycle assessment methodology focused si...
