Machine Tool Operations Quiz

In a lathe, the depth of cut is defined as the:

• Distance the tool moves longitudinally per revolution

• Radial distance between the uncut and cut surface

• Length of the workpiece

• Distance between centers

Which of the following parameters directly affects surface finish during a turning operation?

• Spindle speed only

• Feed rate only

• Tool geometry and feed rate

• Depth of cut only

In facing operation, the cutting tool moves:

• Along the axis of rotation

• Perpendicular to the axis of rotation

• In a spiral path

• In a random circular path

Which operation is used to enlarge an existing hole with better surface finish and accuracy?

• Boring

• Knurling

• Drilling

• Tapping

Knurling operation does not remove material but:

• Adds material by friction welding

• Compresses surface to create a pattern

• Polishes the surface

• Produces threads

The main advantage of using a reamer after drilling is:

• Decreasing machining time

• Achieving better roundness and dimensional tolerance

• Making the hole deeper

• Preventing burr formation

Which of the following operations requires both feed and rotation of the workpiece in a drilling machine?

• Drilling

• Boring

• Tapping

• None of the above

The feed in a drilling operation is defined as:

• Distance moved by the spindle in one revolution

• Depth of the hole

• Diameter of the drill

• Number of revolutions per minute

Which of the following is a peripheral milling operation?

• Face milling

• End milling

• Slot milling

• Plane milling

Slot milling is best suited for:

• Surface finishing

• Generating flat surfaces

• Producing keyways or narrow grooves

• Boring large holes
