UNIT 3 cylindrical grinding,

Which type of grinding machine is used for cylindrical grinding?

• Surface grinding machine
• Centerless grinding machine
• Cylindrical grinding machine
• Tool and cutter grinding machine

What is the workpiece called in cylindrical grinding?

• Grinder
• Lathe
• Grinding wheel
• Cylindrical workpiece

Which abrasive material is commonly used in cylindrical grinding?

• Diamond
• Cubic boron nitride (CBN)
• Silicon carbide (SiC)
• Aluminum oxide (Al2O3)

In cylindrical grinding, what is the difference between the workpiece speed and the grinding wheel speed called?

• Workpiece speed ratio
• Grinding ratio
• Cutting speed difference
• Slip rate

What is the purpose of the coolant used in cylindrical grinding?

• To increase the friction between the workpiece and grinding wheel
• To cool the grinding wheel
• To remove the debris from the workpiece
• To lubricate the grinding wheel

In cylindrical grinding, what is the term used to describe the amount of material removed by each pass of the wheel?

• Depth of cut
• Feed rate
• Wheel grade
• Wheel bond

A cylindrical workpiece of 100mm diameter is being ground with a 50mm diameter wheel at a depth of cut of 0.5mm. What is the workpiece speed if the wheel speed is 30m/s?

• 120 rpm
• 60 rpm
• 240 rpm
• 480 rpm

What is the formula for calculating the metal removal rate in cylindrical grinding?

• MRR = (pi x D x W x d) / 4
• MRR = (pi x D x W x V) / 4
• MRR = (pi x D x W x d x V) / 4
• MRR = (pi x D x W) / 4
