How the Modelling and Fabrication of Abrasive Jet Machine works
- The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine.
- The Air compressor supplies compressed air.
- The Tank, nozzle and plumbing stores and delivers the fluid.

Mechanical viva questions on this project
What is the aim of the Modelling and Fabrication of Abrasive Jet Machine project?
An abrasive jet machine that cuts glass and brittle materials with compressed air and abrasive particles. Air from a compressor passes through a control valve, filter and mixing chamber before blasting through the nozzle.
Explain the working of your project in short.
The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine. The Air compressor supplies compressed air. The Tank, nozzle and plumbing stores and delivers the fluid.
What is the working pressure in a student pneumatic project?
Usually 4–6 bar. Force = pressure × piston area, so a 25 mm bore at 6 bar gives about 290 N.
How does nozzle size affect spraying?
A smaller nozzle gives finer droplets and better coverage at higher pressure, while a larger nozzle gives higher flow with coarser droplets.
Why is mild steel used for the frame?
It is cheap, strong, easy to cut and weld and widely available. A frame of 25 mm square pipe is enough for most student models.
Which material did you select for the main parts and why?
Mild steel (MS) is used for the frame because it is strong, cheap, easy to cut and weld and available everywhere. Shafts are made of EN8 or bright mild steel for strength, and parts that do not carry load can be aluminium or acrylic to reduce weight.
What factor of safety did you take in your design?
A factor of safety of 2 to 3 is taken for static parts and 3 to 5 for parts under shock or fatigue loading. Allowable stress = yield strength ÷ factor of safety, and each part is checked against it.
How did you estimate the cost of the project?
The cost is the sum of raw material, bought-out parts, machining or fabrication and overheads. Our estimate for this model is about ₹9,500 to ₹13,900, depending on size, material and the workshop rates in your city.
Which manufacturing processes were used?
Cutting and grinding of sections, arc or MIG welding of the frame, drilling for mounting holes, followed by assembly, alignment and painting.
