Pretest 2.2 Type A

What is the definition of Turning according to (Groover, 2020)?

• ^{Turning is a machining process in which a single point cutting tool removes material from the surface of a rotating workpiece}

• ^{Turning is a machining process in which a multiple point cutting tool removes material from the surface of a rotating workpiece}

• ^{Turning is a machining process in which a single point cutting tool removes material from the surface of a stationary workpiece}

• ^{Turning is a machining process in which a multiple point cutting tool removes material from the surface of a stationary workpiece} 

The workpiece that is being worked on a lathe is usually ......... in shape

What is the Work Coordinate System (WCS) used in turning operations? 

• X axis and Y axis

• X axis and Z axis  

• Y axis and Z axis

• X, Y, and Z axis  

Finishing is a process to create a smooth surface before roughing.

• True

• False

Which of the following defines feed rate correctly?  

• The speed of rotation (rpm) relative to the cutting tools 

• The workpiece’s distance travelled during one revolution of the spindle (mm/rev)

• The tool’s distance travelled during one revolution of the spindle (mm/rev)  

• The feed rate relative to the spindle speed  

Which one of the following is the benefit of using Autodesk Cam Ultimate?

• Provides only one feature

• Can detect machining errors by simulating the process

• Intermediate user interface with a low level of visualization and modelling

• The tool cannot be edited

What does the color red in the picture indicate?   

• Facing Process 

• Toolpath Errors  

• Cut off Process 

• Machining Errors  

True or False:

If the workpiece does not have a hole, then it also does not have an inside diameter.

• True

• False

What is the direction of tool movement in profile roughing as shown in the picture?

• The tool is moving parallel to the workpiece or in Z-axis. 

• The tool is moving circularly to the workpiece or in X-axis.

• The tool is moving circularly to the workpiece or in Y-axis. 

• The tool is moving perpendicular to the workpiece or in Y-axis
