properties of abrasive machining

Machining Of Boron Carbide (B4C) Process, Applications

The key properties of Boron Carbide, which are of interest to the designer or engineer, are hardness and the related abrasive wear resistance. A typical example of the optimum use of these properties is in the field of abrasive blasting and water jet cutting, where Boron Carbide nozzles are used to withstand the harsh wear regime generated by blasting media such as alumina or silicon carbide grits and slurries.

Abrasive water jet machining of fiber-reinforced composite

Fiber inclusion and the heterogeneous property of composites make it more difficult to machine with the conventional machining process. However, several nonconventional methods have been adopted for machining composites, in which abrasive water jet machining (AWJM) was proven to be more effective and a preferable technique in machining of fiber-reinforced composite material.
