Method And Apparatus For Hard Machining
US Patent:
6733365, May 11, 2004
Filed:
May 10, 2000
Appl. No.:
09/554319
Inventors:
Milton C. Shaw - Tempe AZ
Amitabh Vyas - Wichita KS
Amitabh Vyas - Wichita KS
Assignee:
Arizona Board of Regents - Tempe AZ
International Classification:
B24B 4900
US Classification:
451 21, 451 10, 451164, 451324, 451426
Abstract:
A hard machining process uses a cylindrical tool ( ) of ceramic or other hard machining material of comparatively low cost that provides a circular cutting edge to be engaged in cutting relation with hardened workpiece ( ) to be machined. As tool cutting edge wear occurs, the tool ( ) is rotated through a small angle to bring into contact with the workpiece ( ) a fresh portion of the cutting edge. It is not necessary to rotate that tool ( ) sufficiently to effect replacement of the entire cutting edge portion in engagement with the tool. Sufficient angular movement of the tool is made to replace that of the cutting edge that has the greatest effect on the finish of the machined workpiece ( ), which is the cutting location where the removed chip is thinnest.
Static Mixer
US Patent:
4222672, Sep 16, 1980
Filed:
Apr 19, 1979
Appl. No.:
6/031451
Inventors:
Milton C. Shaw - Tempe AZ
Assignee:
University Patents, Inc. - Norwalk CT
International Classification:
B01F 506
US Classification:
366338
Abstract:
An improved static mixer is disclosed which is capable of efficient mixing and is of a construction which allows relatively inexpensive manufacture. A pair of flow channels are provided for respectively receiving the fluids to be mixed at respective ends thereof. The flow channels have at least one common wall element therebetween, the common wall element having an undulating shape which alternately enlarges and restricts one of the channels while simultaneously alternately restricting and enlarging the other of the channels in opposing relationship. The common wall has openings therein at about the peaks and valleys of the undulations. In operation, two fluids to be mixed are introduced to the respective flow channels. At each peak or valley of the undulating wall element, the opposing enlargement and restriction of the two channels causes a pressure difference and results in a cross flow through the openings in the common wall element. In one form of the disclosed mixer, the common wall element comprises an undulating sheet separating side-by-side flow channels.
