What are the parameters and characteristics of Abrasive jet machining?

The process parameters that control metal removal rate are air quality and pressure, Abrasive grain size, nozzle material, nozzle diameter, stand of distance between nozzle tip and work surface. INTRODUCTION: Abrasives are costly but the abrasive jet machining requires very less investment and less maintenance cost.

What are the process parameters of AJM?

Important process parameters include (i) abrasive particles—its shape, size, strength, material and flow rate; (ii) carrier gas—its nature, composition, flow rate, pressure and temperature; (iii) abrasive jet—mixing ratio, striking velocity, impingement angle and stand-off distance; (iv) nozzle—its profile and inner …

Which type of material 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 materials can water jet cutting be used on?

Some of the typical materials which can be cut by the waterjet cutting process include:

  • Metals. When used for cutting metals, waterjet cutting offers several benefits.
  • Superalloys.
  • Plastics.
  • Glass.
  • Stone and Tile.
  • Ceramics.
  • Rubber and Foam.

What are all the parameters that would affect the MRR in Abrasive jet machining?

The Major Process Parameters that affects the MRR & KERF in AJM are Gas Pressure, Nozzle diameter, Abrasive mass flow rate, Nozzle tip distance [3]. The cut or the hole generated in AJM with a width is called as KERF. The top kerf is wider than the bottom kerf.

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

Which type of materials cannot be machined using Abrasive jet machining? Explanation: Soft materials such as candy bars, thin softwood etc.., cannot be machined using AJM.

What are the factors that affect the material removal rate in AJM process?

There exist many other factors that can influence erosion rate in AJM, for example, size and strength of abrasives, mechanical properties of work surface including strain hardening and residual stress, diameter and wear rate of nozzle, type of cutting, type of carrier gas, etc.

Which type of material Cannot be machined using abrasive jet machine?

Soft materials
Which type of materials cannot be machined using Abrasive jet machining? Explanation: Soft materials such as candy bars, thin softwood etc.., cannot be machined using AJM.

What are all the types of materials which can be machined using?

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

How thick of material can a waterjet cut?

10-12 inches
For hard materials, the maximum cutting thickness of waterjet cutters is taken to be between 25-30 cm (10-12 inches). It is possible to cut an even more thick material, but it can make the process slower than required.

Can you waterjet cut plastic?

Plastic and Acrylic Cutting with Waterjet Unlike abrasive waterjet cutting, however, only pure waterjet is used to cut plastics and acrylics. The clean, very thin waterjet stream (thinner than a strand of human hair) does not cause the material being cut to absorb water, maintaining the integrity of the materials.

What are the factors that affect the performance of water jet machining?

For quality at the cutting head only, these features should be considered for successful abrasive waterjet cutting:

  • Abrasive mixing tube length. A longer abrasive mixing tube generates a more consistent waterjet stream.
  • Alignment of components.
  • Precise orifice.
  • Diameter of stream.
  • Low, controlled stand-off from work.
