Geometric Error Measurement and Identification for Rotational Axes of a Five-Axis CNC Machine Tool

“…Similar to the principle of the R-test, the CapBall was developed by Zargarbashi and Mayer [22] which was a kind of measuring device equipped with a non-contact capacitance sensor. In addition to the aforementioned methods, it is feasible to apply a laser to error measurement in rotational axes [23] and [24]. Wang et al [25] and [26] proposed a method to measure the geometric errors of rotational axes by way of a laser tracker.…”

The Effect of Process Parameters on the Microstructure and Mechanical Performance of Fiber Laser-Welded AA5182 Aluminium Alloys

“…Over the previous two decades, with the wide application of aluminium alloys in automotive, aerospace and other industries, laser welding has become critical joining method. With its high process speeds, single-sided access, no direct tool contact with the workpiece, and being amenable robotic automation, it proved to be an ideal assembly technology for car body fabrication [2]. In comparison to other conventional welding processes, laser welding offers the benefit of a narrow heataffected zone that helps to minimize metallurgical problems [3].…”
