The machines can employ trochoidal dynamic power or high speed cutting strategies for tools rotating as fast as 90,000 rpm.
Though you can track the hurricanes yourself, you do need to be aware of the phenomena of "wobbling", known by forecasters as trochoidal motion.
Kaiser, Gillete and Spinazzola (2010) used a sensory learning program based on the Bolles (2001) proposal, which employs a trochoidal movement table, a computerized light instrument, and an acoustic training game for the purpose of creating interactions between the visual, auditory, and vestibular systems to bring about improvements in sensory integration and adaptive body responses.
The main reasons are the adaptive control of the tool and the growing use of trochoidal tool path generation.
Although conventional internal gear oil pumps with a trochoidal tooth profile are considered to have low pumping efficiency [6][7], the total efficiency of the new pump was increased by adopting a new rotor with a refined tooth profile.
[5] introduce an idea on using circle curve to replace standard trochoidal root fillet with BEM.
With increasing wind speed, the shapes of the sea waves become more trochoidal, and the motions of the facets on the sea surface are no longer closed orbits.
A few isolated trochoidal (symmetrical) sharp-crested sandwaves are oriented normal to the mussel reefs (Figs 4, 5).
Modern trochoidal and plunge milling strategies, combined with rigid holders and the new milling tools on the market, let even low-end machines achieve considerable chip volume with no loss of speed or performance.
