Which CAD software can be used to create data for prototyping machine?
The software most frequently used in prototyping includes SketchUp, AutoCAD, SolidEdge and SolidWorks.
What is rapid prototyping in software development?
Rapid prototyping is the creation of product simulations to be used for testing and validation during the product development process, with multiple iterations generated during a short period of time-based on user feedback and analysis.
Which one is the design process in rapid prototyping?
Rapid prototyping is the fast fabrication of a physical part, model or assembly using 3D computer aided design (CAD). The creation of the part, model or assembly is usually completed using additive manufacturing, or more commonly known as 3D printing.
What is the format for prototyping machine?
STL file format
Which material is not available for LOM process?
The resins are limited to those objects made using paper or plastic. Metal sheets are welded (either thermal brazing or ultrasonic welding) or bolted together to form the part. The use of metal in the LOM process is rare.
Which one of the processes is not using a laser?
Which of the following processes does not use lasers? Explanation: Laser Beam Machining or more broadly laser material processing deals with machining and material processing like heat treatment, alloying, cladding, sheet metal bending, etc.
What are the values of current densities required in IBM?
What are the values of current densities required in IBM? Explanation: The value of current density of about 0.85 mA/cm2 is required for machining the work piece materials in Ion beam machining.
Which of the following laser is the most efficient?
Which of the following laser is the most efficient? Explanation: The electric discharge style CO2 gas lasers are the most efficient type currently available for high power laser beam material processing.
Which of the following is not an advantage of LBM?
1. Which of the following is not an advantage of LBM? Explanation: Rapid machining, low operating cost and no tool wear are some of the advantages of Laser beam machining. 2.
What is LBM process?
Laser beam machining (LBM) is a non-conventional Machining manufacturing process, a form of machining, in which a laser is directed towards the work piece for machining. This process uses thermal energy to remove material from metallic or nonmetallic surfaces.
What is the full form of LBM in advanced machining processes?
Laser Beam Machining (LBM) is one of the most popular non conventional machining processes used in the area of advanced machining. From: Modern Machining Technology, 2020.
Which of the following has highest rate of material removal?
– Generally the rate of metal removal for various machining processes are as follows:
- Electric Discharge Machining (EDM) has metal removal rate of about 10-20 mm3/s.
- Electro-Chemical Machining (ECM) has the highest metal removal rate of about 200-300 mm3/s.
What are the values of gaps between the electrodes in EDM?
What are the values of gaps between the electrodes in EDM? Explanation: In EDM, very small gaps that range between 0.01 – 0.5 mm are maintained.
What are the values of current densities used in ECM?
Explanation: Current density values in ECM range between 5 to 500 A/cm2.
Why electrolyte is used in ECM?
The electrolyte has three main roles in the ECM process; it carries the current between the tool and the workpiece,4,25,31 it removes the products of the reaction from the IEG2,5,9,10,29,31–33 and it removes the heat produced from the passage of the current.
Which of the following processes can be done using ECM?
2. Which of the following processes can be done using ECM? Explanation: ECM can be used for die sinking, trepanning, drilling, contouring, grinding and profiling.
What are the tolerance values for the side gap in ECM?
12. What are the tolerance values for the side gap in ECM? Clarification: The dimensional tolerances obtained for side gaps are ± 0.25 mm. 13.
What is the life of tungsten carbide material nozzle?
For average material removal, tungsten carbide nozzles have a useful life of 12 to 30 hours, and sapphire nozzles last about 400 hours. The distance of the nozzle from the workpiece affects the size of the machined area and the rate of material removal.
What is the material of nozzle in the AJM process?
AJM nozzle is usually made of tungsten carbide or sapphire ( usually life – 300 hours for sapphire , 20 to 30 hours for WC) which has resistance to wear. The nozzle is made of either circular or rectangular cross section and head can be head can be straight, or at a right angle.
How is the material removed in abrasive water jet machining?
Explanation: In Abrasive water jet machining, material removal takes place by the erosion of the work piece material using abrasives accelerated by jet stream.
What are the values of jet velocities in water jet machining *?
What are the values of jet velocities in Water jet machining? Explanation: Velocity of the water jet stream ranges between 540 – 1480 m/s in WJM.
Which device is used in WJM to pressurize the water?
The flow of the water is regulated with the help of flow regulator. It is device which is used to convert pressure energy of water into kinetic energy in water jet machining. Here nozzle converts the pressure of water jet into high velocity beam of water jet.
