Test results on leakage and rotordynamic coefficients are shown for the three-teeth-on-stator staggered labyrinth seal with the tooth radial clearance of 0.5 mm.
Experiments were performed based on L18 standard orthogonal array design by five input process parameters, namely cutting speed, feed per tooth, radial depth of cut, cutting time and cutting environment.
The major characteristics indexes for performance selected to evaluate the processes are tool life and metal removal rate, and the corresponding cutting parameters are milling type, spindle speed, feed per tooth, radial depth of cut, and axial depth of cut.
The field enhancement of the nano-antenna can be tuned by geometric parameters such as the outer radius, the tooth angle, and the ratio of the radial sizes of successive teeth, which provide control over both the spectral resonance position and the field enhancement peak amplitude.
Among the machines utilizing a rotating steel disk with peripheral teeth, the radial-arm saw is one of the most useful.
Diphydontosaurus is one of the least phylogenetically nested rhynchocephalians, but the stout teeth with prominent radial ridges of the Vinita specimen [ 14] suggest a closer affinity to the more derived Planocephalosaurus from the Late Triassic of the UK [ 22].
Axial force is greater than the tangential force and the radial force on the same tooth.
Response surface methodology was planned to carry out the experiments and further genetic algorithms were implemented to obtain the optimal parameters such as the cutting speed, feed per tooth, axial and radial depth of cut.
The assumptions made with the modified Lewis formula are that the full load is applied to a single tooth and the radial component force (F) is ignored and also that the force is distributed evenly over the full face width of the tooth and that the stress concentration effect of the tooth fillet is also ignored.
Tooth interference, normally avoided altogether by adhering to standard design guidelines, becomes a concern when non-standard tooth forms with reduced radial clearance are employed, such as large-fillet short-dedendum gears.
The influence of cutting speed, feed per tooth, axial depth and radial depth of cut is studied using a 24−1 fractional factorial design of experiments.
