1. What is the primary purpose of a press brake in metal fabrication?
A. Cutting sheet metal
B. Bending sheet metal
C. Punching holes
D. Welding joints
Bending sheet metal is the primary function of a press brake in
forming precise angles and shapes in sheet stock.
2. Which component of a press brake holds the punch?
A. Die block
B. Back gauge
C. Ram
D. Foot pedal
The ram is the moving part that carries and secures the punch for
bending operations.
3. What type of tooling is typically used on the bottom of a press brake?
A. Punch holder
B. Die
C. Clamping bar
D. Stripper plate
The die sits on the press bed and works with the punch to form the
bend in the metal.
4. Which of the following is critical for determining bend allowance?
A. Material hardness only
B. Press tonnage only
, C. Material thickness and bend radius
D. Die height only
Bend allowance calculation requires both material thickness and the
intended internal radius to predict flat length.
5. What is the purpose of the back gauge on a press brake?
A. Hold the workpiece during welding
B. Lubricate tooling
C. Position the workpiece for accurate bends
D. Adjust punch clearance
The back gauge positions the material so each bend is made at the
correct distance from the edge.
6. What unit is press brake tonnage usually measured in?
A. Newtons
B. Kilograms
C. Tons
D. Pounds per square inch
Press brakes are rated in tons to indicate the maximum force
capacity for bending operations.
7. Why is it important to calculate correct bend deduction?
A. To increase punch speed
B. To determine accurate flat pattern length
C. To reduce material cost
D. To set press temperature
Bend deduction calculates the amount of material used in the bend
area, ensuring correct final part length.
8. What material property most influences springback?
A. Color
B. Elasticity
C. Hardness only
D. Surface finish
Springback depends on elasticity, the tendency of the material to
return toward its original shape after bending.
9. Which safety device stops the press brake when the operator’s hands
are detected in the danger zone?
A. Limit switch
, B. Pressure gauge
C. Light curtain
D. Back gauge
Light curtains detect interruptions in infrared beams and stop the
machine to protect the operator.
10. What type of bend results in material overlapping itself?
A. V-bend
B. Roll bend
C. Hem bend
D. Coining
A roll bend gradually curves material into a shape where it may
overlap, common in forming rings or coils.
11. What is coining in press brake operations?
A. Cutting metal
B. Applying high pressure to finalize the bend
C. Shearing edges
D. Heating material
Coining involves pressing the material deeply into the die to reduce
springback and increase precision.
12. Which punch angle is commonly used for bending 90° on a press
brake?
A. 30°
B. 60°
C. 90°
D. 120°
A 90° punch matched with an appropriate die generally produces a
right-angle bend.
13. What factor determines the selection of V-die width?
A. Machine color
B. Material thickness
C. Springback only
D. Sheet width
V-die width selection depends on material thickness to ensure proper
bend radius and force distribution.
