Noise reduction by using smoothed corner at a duct exit

2005
In this study, the method of a smoothed corner that replaces a commonly used sharp convex corner is employed for noise reduction. The effects of the two parameters — the smoothing angle and the radius of the smoothed surface on the flow structure are investigated. It is found that the larger smoothing angle and the larger radius of the smoothed surface

Smoothing of optical surface corners by abrasive polishing with a plate spring

SPIE Proceedings, 2015
We propose a new method for polishing the corners of optical surfaces that uses a plate spring as a polishing tool. In this method, a polishing pad is fixed to the tip of a plate spring, which moves back and forth on a workpiece surface. During the polishing, the plate spring is bent while maintaining a constant amount of deflection to generate a ...

A Vector Based Smoothing Algorithm of High Speed Motion at Trajectory Corner

2009
To ensure the quality of products and efficiency of machining and to protect the machine tools from damage in high speed working conditions, one of the key solutions is to smooth the feedrate profile at the corner of two adjoining moves. In the paper, a vector based look-ahead algorithm is presented for feedrate smoothing at trajectory corner by ...

Loci Conversion and Corner Smoothing with PH Curves in CNC System

Key Engineering Materials, 2009
Free-form surface interpolation functions give more advantages in machining than the traditional line and circle functions. A method is developed to convert lines and circles into Pythagorean-hodograph (PH) curves. In order to get smooth machining process the PH curve is used to replace the joints of the circular/linear elements by the connection ...

Conditional sampling of the turbulent vorticity field near a smooth corner

Physics of Fluids, 1998
The turbulence source terms in the equation for the mean vorticity near the walls of a smooth corner are examined through correlations involving the fluctuating vorticity field. A manifestation of the corner effect is the specific asymmetries of the estimated probability density functions for the production terms.
