Animal brains of all sizes, from the smallest to the largest, work in broadly similar ways. Studying the brain of any one animal in depth can thus reveal the general principles behind the workings of all brains. The fruit fly Drosophila is a popular choice for such research. With about 100,000 neurons – compared to some 86 billion in humans – the fly brain is small …

Douglas Thorby, in Structural Dynamics and Vibration in Practice, 2008. 10.4.1 The Frequency Response Function. The FRF, usually denoted by H (ω) or H(f), depending on whether it is expressed in terms of rad/s or Hz, respectively, is simply the ratio of the steady-state response of a system to an applied sinusoidal input, which can be a force, an imposed displacement, or …

Multi-blade face milling cutters are widely used in the finish machining of mechanical parts. The cutting force in the milling process is a crucial factor that promotes the chatter of the machine spindles, which can be used to predict the machined surface roughness. In this paper, a novel cutting force prediction model based on non-uniform rational basis splines …

The dynamic 3-axis milling head M3ABC (A, B and C axis) sets new standards in volume cutting of aluminum, composite and model construction materials as well as in HSC machining of steel and cast iron. Where conventional 2-axis milling heads reach their performance limits, the M3ABC allows different workpieces to be machined four times faster.

Milling tool wear state recognition plays an important role in controlling the quality of milled parts and reducing machine tool downtime. However, the characteristics of milling process limit the accuracy and stability of tool condition monitoring (TCM) employing vibration signals. To improve this problem, this paper explores the use of vibration signals as sensing approach for …

Fig. 20 depicts the results of a sound source localization on a milling machine. If the machine is idling, the maximum of sound emission at approximately 62 dB(A) is caused by the spindle. On the right hand, while machining processes, the main sound emission develops because of the vibration of the workpiece.
