Abstract: Catastrophic and premature bearing failure caused by excessive thermally induced bearing preload is a major design problem for spindle bearings of high-speed machine tools. Due to a lack of a ...

Abstract: Modern machine tools are required to operate at wide speed ranges for higher productivity and quality. Because spindle bearings generate a large amount of heat at high speeds, the compensation ...

Abstract: Penetration depth is an important factor critical to the quality of a laser weld. This paper presents a 3D heat conduction model with a moving line source to correlate the temperature measured ...

Abstract: Industrial laser systems handle high power consumptions and may function under undesirable operating conditions if the systems are not properly maintained. It is sometimes difficult to diagnose ...
