According to the previous experimental studies on the  ceramic composite armors [7, 8], in the wear test, the performance parameters of the bit and the machining technological parameters have been determined, as listed in Table 1, along with the number of holes that each bit have accomplished until scrapped. 3.
Advanced Aluminum Powder Metallurgy Alloys and Composites / nitride cutting tools are needed for effective ma- chining. The high-cost conventional machining of MMCs can be eliminated by near-net shape manufacturing or by noncontact machining tech- niques such as laser processing (Ref 32) and abrasive waterjet cutting (Ref 33). In this work, grinding test was performed in terms of machining parameters, such as grinding speed, feed rate, etc., in order to study effect of ultrasonic vibration in grinding. The design of experiment (DOE) approach was used for an optimal condition of ultrasonic assisted grinding, which can minimize the grinding forces. In DOE, ultrasonic amplitude power, feed rate, and rotation speed of Cited by: 2.

A REVIEW ON THE ROTARY ULTRASONIC MACHINING OF ADVANCED CERAMICS metal-bonded diamond abrasives in rotational motion, ultrasonically vibrated For ceramic matrix composite like C/SiC. Silicon carbide of the regular type is used for grinding cast iron and nonferrous metals, and a special high purity type is used occasionally for the rough grinding of cemented carbides.
Diamond. wheels, however, are preferable and are always used for cemented carbide finish grinding. The grain size generally varies over a narrow range only. The abrasive wear of a series of diamond and tungsten carbide (WC)-based metal matrix composites has been examined using both low stress scratching abrasion (rubber wheel) and high stress grinding.

However, ceramic matrix composites reinforced with ceramic fibers or whiskers may present K Ic values from 6 to 20 MPa (m) 1/2 .
For glasses and glass-ceramics those values range from to or up to MPa (m) 1/2, respectively [2, 3].The difficulty issue in machining of metal matrix composites (MMCs) is one of the major problems that are preventing its wide spread in engineering application. 19 These composite materials are anisotropic, non-homogeneous and their hard ceramic reinforcing fibers or particles are very abrasive and make these materials difficult to form and.at precious minerals.
