20090112354 | METHOD OF DETERMINING OPTIMAL PARAMETERS FOR MACHINING A WORKPIECE - A method of determining optimal parameters for machining a workpiece comprises performing a first computer simulation to determine parameters for machining a workpiece, including a tool nose radius and a tool rake angle, performing a second computer simulation to determine additional parameters for machining a workpiece, including a tool rotational speed and tool feed speed, and performing a third computer simulation to optimize the parameters for a desired tool path. A method of machining a green or bisque ceramic workpiece contacts the workpiece with a tool using a negative rake angle. | 04-30-2009 |
20120055327 | ARMOR SYSTEM HAVING CERAMIC MATRIX COMPOSITE LAYERS - An example armor system includes a first ceramic matrix composite armor layer, a second ceramic matrix composite armor layer, and a monolithic ceramic armor layer directly bonded to the first and the second ceramic matrix composite armor layers. | 03-08-2012 |
20130004325 | HYBRID PART MADE FROM MONOLITHIC CERAMIC SKIN AND CMC CORE - A hybrid part for use in a gas turbine engine has a platform and an attachment feature. The platform and an exterior portion of the attachment feature are formed from a monolithic ceramic material. A ceramic matrix composite material is located adjacent interior portions of the platform and the attachment feature and is bonded to the monolithic ceramic material. | 01-03-2013 |
20140178196 | TURBOMACHINE WITH CLAMP COUPLING SHAFT AND ROTOR HUB TOGETHER - A turbomachine includes a rotor hub that has a central opening there through. A shaft extends through the central opening. A clamp is coupled with the shaft and the rotor hub such that the rotor hub is rotatable with the shaft. | 06-26-2014 |
