With the development of motorized spindle, cooling effect and distribution capacity become crucial problem system. An optimization method for thermoelectric-based system (TECS) is proposed based on conservation energy to distribute capacity. The main strategy make cold heat input at different regions spindle sleeve equal in real-time through optimizing contact area between conduction (HCS) slee...

In this paper, the method of harmonic suppression and torque ripple reduction is studied for structure characteristics design requirements a high-speed permanent magnet spindle motor. According to magnetic circuit analysis calculation theory synchronous motor (PMSM), reluctance slots are arranged at two ends rotor yoke change external field distribution in order optimize air gap density wavefor...

Vol. 216 No. 6 1525–1531 https://doi.org/10.1083/jcb.201612064 Introduction During eukaryotic cell division, the mitotic spindle mediates the separation of chromosomes into the two daughter cells (Gadde and Heald, 2004; Kapoor, 2017). Microtubules within the spindle are organized in a dense array, with their positions, orientations, len...

Abstract The aluminium alloys 5052 and 6082 are extensively used in manufacturing lighter structural members, having improved strength resistance to corrosion. Magnesium (Mg) Chromium (Cr) powder were the filler materials selected for enhanced corrosion protection properties this investigation. Friction stir welding (FSW) process parameters viz., spindle speed, shoulder penetration, centre dist...

High-speed motorized spindle heating will produce thermal error, which is an important factor affecting the machining accuracy of machine tools. The error model high-speed spindles can compensate for and improve effectively. In order to confirm high precision model, Beetle antennae search algorithm (BAS) proposed optimize prediction based on BP neural network. Through characteristic experiment,...

Grinding is a critical surface-finishing process in the manufacturing industry. One of challenging problems that specific grinding energy greater than ordinary procedures, while efficiency lower. However, an integrated model and analysis distribution during still lacking. To bridge this gap, time history first built to describe cyclic movement air-cuttings, feedings, cuttings. Steady transient ...

060A4 steel (Chinese standard) is a with good machinability, which very popularly used in mechanical engineering. Therefore, the study of solutions for improvement quality and productivity when machining this type has great technical economic significance. In study, multi-objective optimization process been performed milling on vertical machine. The cutting tool face cutter made High Speed Stee...
