Keep in mind that while smaller stepovers generally produce a finer surface finish, there is a point of diminishing returns. Extremely small stepovers may increase machining time significantly without a proportional improvement in surface roughness (often quantified as Ra). Therefore, balancing step...

The nozzle output diameter has a direct effect on the accuracy and surface finish of the produced objects, as smaller diameters produce objects with fine details and high resolution. Nonetheless, it has a negative effect on the printing speed as a smaller diameter causes a lower material flow ...
Improved surface structures have been achieved by optimizing various scanning parameters [34,97].(9)Ra=1.682+0.059A+0.076B+0.274C−0.072A×B+0.052A×C−0.225A2−0.072A2×Bwhere Ra is the predicted average surface roughness, laser power is A, scanning speed is B, and hatching space ...
The surface micro-notch effect was assessed through the stress concentration factor (k t ). The results indicated attenuation of the average roughness (Ra) by around 30% for iron and 70% for Inconel when laser remelting was employed. In addition, k(t) presented a 31% reduction for iron ...
According to IB specification [2], users can configure timeout and retry_cnt pa- rameters to specify the minimum retransmission timeout (4.096µs ∗ 2timeout ) and the maximum number of times that the QP tries to resend packets. We note that NVIDIA NICs have a new feature called ...
Nana nei i tiki mai whakawhiti te ra A, upane! ka upane! A, upane, ka upane, whiti te ra! One of the most visceral and dramatic moments across all sports, the haka is synonymous with Maori culture in New Zealand and All Blacks rugby. When the team played the United States in ...

The rotating disk surface adsorption shear device used in this work was developed at UCL to mimic loss of protein to aggregation experienced through solid–liquid interfacial effects particularly during fill-finish operations.13 Monomer loss from prolonged operation of the device follows first-order ...
