What is the main distinction between sheet metal and plate in terms of thickness?
Plates are thicker than 6mm, and sheets are less than 6mm
Plates are less than 6mm, and sheets are thicker than 6mm
Plates are thinner than sheets
Plates are measured in meters, and sheets are measured in millimeters
What is the primary purpose of shearing in sheet metal processes?
To bend the sheet metal
To weld two sheets together
To remove a blank of suitable dimensions
To heat-treat the sheet metal
In shearing, as the clearance between the punch and die increases, what is the effect on punch force?
Punch force increases
Punch force decreases
Punch force remains constant
Punch force fluctuates
Which operation involves punching holes in a sheet without removing any material?
Perforating
Parting
Notching
Lancing
What type of die allows several operations to be performed in one stroke at a single station?
Progressive die
Transfer die
Compound die
Segmented die
What is the purpose of beading in sheet metal processes?
To reduce material thickness
To improve the appearance and stiffness of the part
To remove burrs from the edges
To punch holes in the sheet
In stretch forming, how is the sheet metal positioned during the process?
It is held at the center and stretched radially
It is clamped along the edges and stretched over a male die
It is heated and compressed into a mold
It is rolled into a cylindrical shape
Which process involves folding the edge of a sheet over itself?
Flanging
Hemming
Beading
Bulging
What is the advantage of using polyurethane plugs in the bulging process?
They increase punch force
They are resistant to abrasion and wear
They require lubrication for smooth operation
They reduce springback in bending
In the manufacturing of metal honeycomb structures, what is the primary function of the corrugation process?
To cut the sheet into desired lengths
To apply adhesive to node lines
To pass the sheet through rolls to create corrugations
To bond the corrugated sheet to outer skins
