US Classification:

700160, 2988923, 700159, 703 7

Abstract:

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.

Abstract:

Components with improved erosion resistance are disclosed. A surface of the component or a substrate of the component is modified by coating the substrate with an elastomer layer. The elastomer layer is then modified by embedding hard particles onto an outer side of the elastomer layer. The hard particles exhibit higher fractured toughness providing enhanced erosion protection. The elastic properties of the elastomer experience little reduction because the surface embedded particles are located only at the outer side or outer surface of the elastomer layer. Therefore, the bond between the inner side of the elastomer layer and the substrate or component surface is not interfered with and the potential for electro-chemical corrosion and poor adhesion are not increased by the presence of the hard particles as the hard particles are located away from the inner face between the elastomer layer and the substrate.

International Classification:

B21D 26/02

US Classification:

72 56

Abstract:

A method for peening a surface of a material is disclosed. The method may include producing repeated, separated and high speed liquid drops and moving the liquid drops across the surface to be peened. The liquid drops are essentially free of air bubbles and the velocity of the liquid drops is at least 500 ft/sec. A peening apparatus to produce repeated, separated and high speed liquid drops is also disclosed. The apparatus may comprise a storage tank, a nozzle, a pump, an accumulator, a regulator and an actuator. The apparatus may control the volume and velocity of the produced liquid drops as well as the frequency of the liquid drop production.

Abstract:

A reactor for continuously coating tow fibers has an outer tubular member, an inner support member spaced from the outer tubular member, a reactant flowing through a space defined by the outer tubular member and the inner support member, and at least one flow promotor located on an outer surface of the inner support member for directing the reactant towards an inner surface of the outer tubular member. A system and a method for coating tow fibers are also described.
