Abrasive Water Jet Machining Line Diagram

Introduction and abrasive jet machining.

Abrasive water jet machining line diagram.

Abrasive water jet machining awjm is non traditional or non conventional machining process. It uses water jet working as a tool to cut the metal. Abrasive jet machining is a non traditional machining process which is mostly used in machining of hardened metals. Abrasive water jet machining developed in 1974 to clean metal prior to surface treatment of the metal.

Today we will learn about water jet machining and abrasive water jet machining principle working equipment s application advantages and disadvantages with its diagram. Jigs and fixtures for machine shops. It consists of a mixing chamber gas filter pressure gauge regulator and the nozzle. The figure shown is the above abrasive jet machining.

Ultrasonic machining usm water jet and abrasive water jet machining. The abrasive particles are held in a suitable holding device like a tank and fed into the mixing chamber. There are few process parameters that affect the quality of the workpiece surface cut by awjm namely hydraulic pressure standoff distance abrasive flow rate and types of abrasive 48. The vortex motion of the.

Figure 2 1 schematic diagram of abrasive water jet machining set up 59 the compressed air from the compressor enters the mixing chamber partly prefilled with fine grain abrasive particles and chemical. In this process a high speed well concentrated water jet is used to cut the metal it uses the kinetic energy of water particle to erode metal at the contact surface the jet speed is almost 600 m s. A typical material removal rate for abrasive jet machining is 16 mm min in cutting glass. A typical set up for abrasive jet machining is shown in the figure.

Process parameters in abrasive water jet machining awjm 46. In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining. The filtered gas at a pressure of 2 to 8 kgf cm 2 is supplied to the mixing chamber containing the abrasive powder and. Types of unconventional machining process manufacturing working.

Design and application of typical jigs and fixtures. Purposes of jigs and fixtures and their design principles. Principle of water jet machine this process works on the basic principle of water erosion. 1 6 shows the schematic diagram of awjm for hole making on composite materials.

In order to cut harder materials like metals or granite an abrasive material is mixed in the water.
