Historically, standardized test parts are used to quantitatively evaluate the performance of a machine or process. While several different additive manufacturing (AM) test parts have been developed in the past, there are no current standard test parts. This paper reviews existing AM test parts, discusses the purposes of the studies, and describes important features and characteristics found in ...

This paper presents a method to investigate the characteristics of a high-speed motorized spindle system. The geometric quality of high-precision parts is highly dependent on the dynamic performance of the entire machining system, which is determined by the interrelated dynamics of machine tool mechanical structure and cutting process. This performance is of great importance in advanced, high-p...

Bearings are a common component and crucial to most rotating machinery. Their failures the causes for more than half of total machine failures, each with potential cause extreme damage, injury, downtime. Therefore, fault detection through condition monitoring has significant importance. Since initial cost standard techniques such as vibration signature analysis is high long payback period, via ...
