Ultrasonic Machining (USM) Common tool materials used in USM include soft steel and stainless steel. Abrasive materials in USM include boron nitride, boron carbide, aluminum oxide, silicon carbide and diamond. Grit sizes ranges between 100 and 2000 microns The vibration amplitude should be set approximately equal to grit size, and the gap size should be maintained at about two times grit size.

Manufacturing Technology Grinding Grinding is the most common form of abrasive machining. It is a material cutting process which engages an abrasive tool whose cutting elements are grains of abrasive material known as grit. These grits are characterized by sharp cutting points, high hot hardness, chemical stability and wear resistance. The grits are held together by a suitable bonding material ...
plastic abrasive polishing tool. The tool is a pad or layer of abrasive-laden elastic plastic medium (similar to that used in two way abrasive flow finishing), but typically higher in viscosity and more in elastic.
Abrasive waterjet machining (AWJM) is a new machining process, the advantages of which include low cutting temperatures, no heat damage to the material being cut, minimal dust, and low cutting forces.
form of a pure waterjet or abrasive waterjet and then applied to the workpiece causing microerosion. The cutting water works as a cooling agent of cutting edge, thus allowing for a very high quality cut. The one main component which is without any doubt always necessary to create a …
•It is abrasive and gives better MRR and surface finish •But costlier than copper –Copper •Second choice for tool material after graphite •Can be produced by casting or machining •Cu tools with very complex features are formed by chemical etching or electroforming –Copper-tungsten •Difficult to machine and also has low MRR
Abrasive Jet Machining is a material removal process with the help of concentrated abrasive grains enclosed in a nozzle that removes by the action of impact erosion. In abrasive-jet machining, a high-velocity jet containing abrasive particles is aimed at the workpiece surface under controlled conditions.
The machining of very hard materials is done by using Cubic Boron Nitride (CBN) abrasives. CBN is as hardest as diamond so it is used in place of the diamond because we cannot use diamond as an abrasive because diamond will diffuse the carbon atoms into the work piece due to this the machineability of the work piece will decrease.
AWJM, the abrasive particles are allowed to entrain in water jet to form abrasive water jet with significant velocity of 800 m/s. Such high velocity abrasive jet can machine almost any material. Fig. 1 shows the photographic view of a commercial CNC water jet machining system along with close-up view of …

ABRASIVE JET MACHINE (AJM) BY – VIVEK PATEL f Introduction Abrasive Jet Machining (AJM) is a process that removes material by directing a high velocity stream of abrasive particles onto workpiece. The process is used chiefly to cut intricate shapes in hard and brittle materials which are sensitive to heat and have a tendency to chip easily.

General Water Jet Machining Process Parameters: the general domain of parameters in entrained type AWJ machining system is given below: • Orifice – Sapphires – 0.1 to 0.3 mm • Focussing Tube – WC – 0.8 to 2.4 mm • Pressure – 2500 to 4000 bar • Abrasive – garnet and olivine – #125 to #60 • Abrasive flow – 0.1 to 1.0 Kg/min
ABRASIVE MATERIALS The abrasive grains are the cutting took of a grinding wheel. They actually cut small pieces or chips off the work as the wheel rotates. The shape of each grain is irregular with several sharp cutting edges. When these edges grow dull, the forces acting on the wheel tend to fracture the abrasive grains and produce new cutting ...

ABRASIVE JET MACHINING Definition: In abrasive jet machining, a focused stream of abrasive particles, carried by high pressure air or gas is made to impinge on the work surface through a nozzle and the work material is made to impinge on the work surface through a nozzle and work material is removed by erosion by high velocity abrasive particles.
Abrasive water jet cutting is one of the most recently developed non-traditional manufacturing technologies. The general nature of flow through the machining, results in rapid wear of the nozzle which decrease the cutting performance. It is well known that the inlet pressure of the abrasive water suspension has main effect on the erosion characteristics of the inner surface of the nozzle.
