What is the application of abrasive jet machining?

What is the application of abrasive jet machining?

In the form of abrasive jet it is used for machining like cutting, drilling, and engraving of brittle materials. Surface fast cleaning and preparation are done by using abrasive jet for welding and plasma spray coatings. The erosion tests of turbine blades, propellers are done by using abrasive jet application.

What are the parts of abrasive jet machining process?

Abrasive Jet machining Consists of several Parts like:

• Gas Supply.
• Filter.
• Pressure Gauge.
• Regulator.
• Mixing chamber.
• Nozzle.

What are the process parameters in abrasive water jet machining?

Abrasive water jet machining process has various machining process parameters, i.e., traverse speed, abrasive flow rate, standoff distance, water pressure, and abrasive size. These parameters in turn will affect the performance parameters, like kerf width, surface roughness, taper angle, and material removal rate.

What is the principle of ultrasonic machining?

It works on the same principle of ultrasonic welding. This machining uses ultrasonic waves to produce high frequency force of low amplitude, which act as driving force of abrasive. Ultrasonic machine generates high frequency vibrating wave of frequency about 20000 to 30000 Hz and amplitude about 25-50 micron.

What is the principle of USM?

Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles.

Which type of materials can be machined using Abrasive jet machining?

Explanation: Materials like ceramics, glass, hard and super hard materials can be machined using Abrasive jet machining.

What are the types of abrasives used in USM?

The abrasives used for the USM process include diamond, cubic boron nitride, boron carbide, silicon carbide, and aluminum oxide. Boron carbide is the most widely used abrasive material.

Which of the following is not used as abrasive in ultrasonic micro machining?

1. Which of the following materials is not used as abrasive in ultrasonic machining? Diamond.

What is the principle of EDM?

Working principle: The principle of working of EDM is based on the erosion of the material by repetitive sparks between the workpiece and the tool submerged in a bath of the dielectric medium. The working system is illustrated in Fig. 2.1. The workpiece and tools are two electrodes connected by D.C pulse generator.

Which gas is used in abrasive jet machining?

carrier gas
In abrasive jet machining jet is produced by mixing the gas with abrasive particles. The gas used is called as carrier gas. Some of the most common carrier gases employed are air, carbon dioxide nitrogen. Oxygen is never used as a carrier gas as it may oxidize the surface of the work piece.

Which type of materials Cannot be machined using abrasive jet machining?

Question 99 : In Abrasive jet machining, intricate shapes and holes are machined on which type of materials? Question 100 : State whether following statement is true or false. ‘Using abrasive jet machining, wire cleaning and insulation stripping takes places without affecting the conductor. ‘

What is the principle process of abrasive jet machining?

If a high velocity abrasive particles strike on a hard or brittle work piece, it remove some metal at the striking surface. This metal removal process takes place due to brittle fracture of metal and also due to micro cutting by abrasive particle. This is principle process of abrasive jet machining.

What is high velocity abrasive machining?

These high velocity abrasive particles remove metal by brittle fracture or erosion from work piece. This machining process works on the basic principle of abrasive erosion.

What is the basic principle of machining?

This machining process works on the basic principle of abrasive erosion. If a high velocity abrasive particles strike on a hard or brittle work piece, it remove some metal at the striking surface. This metal removal process takes place due to brittle fracture of metal and also due to micro cutting by abrasive particle.

What is the abrasive particle size and jet velocity?

In this machining, the Abrasive particle size is 10-40 Micros. Jet velocity will be 150 to 300 m/sec and It is used for superalloys and Hard Materials. Let’s dive into it.
