Name the three categories of workshop process used to shape and assemble prototypes.
Show answer
Wastage, addition, and deforming/reforming.
What is a wastage process in manufacturing?
Show answer
A process that removes material to create the shape — e.g. sawing, drilling, cutting, turning.
Sawing, drilling and turning timber belong to which category of process?
Show answer
Wastage — material is cut away.
Which wastage process is typically used in design engineering (e.g. for PCBs)?
Show answer
Etching — unwanted material is chemically removed.
What is an addition process in manufacturing?
Show answer
A process that joins or builds up material — e.g. adhesion, welding, riveting, sewing, laminating.
Welding, brazing and riveting metals are examples of which category of process?
Show answer
Addition — they join separate pieces together.
Which addition process is used to join components in design engineering (electronics)?
Show answer
Soldering.
Heat welding is an ? process used to join polymers.
Show answer
addition
What is a deforming and reforming process in manufacturing?
Show answer
A process that changes the shape of material without removing or adding any — e.g. bending, pressing, moulding, casting.
Vacuum forming and line bending polymers belong to which category of process?
Show answer
Deforming and reforming — the polymer is reshaped using heat.
Which two deforming processes are used to shape timber?
Show answer
Steaming and pressing.
Pleating and gathering fabric are examples of which category of process?
Show answer
Deforming and reforming — the fabric is reshaped, not cut or joined.
