What is the key advantage of additive manufacturing (3D printing) over traditional subtractive machining for complex parts?
Answer: Ability to create internal geometries and complex shapes impossible to machine
Additive manufacturing builds parts layer by layer, enabling internal channels, lattice structures, and geometric complexity that cannot be achieved with subtractive machining.
When using statistical process control (SPC), a process is considered 'out of control' when:
Answer: A data point falls outside the control limits or a non-random pattern appears
SPC signals an out-of-control condition when a point falls beyond the ±3σ control limits or when non-random patterns (runs, trends, clusters) appear in the data.
What is the function of a 'bill of materials' (BOM) in manufacturing?
Answer: To itemize all components, subassemblies, and raw materials required to build a product
A BOM is a hierarchical list of all parts, subassemblies, and raw materials — with quantities — required to manufacture a finished product.
In extrusion manufacturing, a 'die' is used to:
Answer: Shape the cross-section of the material as it is forced through an opening
The extrusion die contains an opening whose profile determines the cross-sectional shape of the extruded product, such as rods, tubes, or complex profiles.
A 5S program in a manufacturing facility stands for Sort, Set in Order, Shine, Standardize, and:
Answer: Sustain
The fifth S is Sustain (Shitsuke), which means maintaining and reinforcing the first four S disciplines through training, audits, and continuous adherence.
Which fastener type is designed to be installed and removed without access to the back (blind) side of the workpiece?
Answer: Blind rivet (pop rivet)
A blind rivet (pop rivet) is inserted from one side only; when set, the mandrel expands the rivet tail on the blind side, creating a secure joint without back-side access.
What does 'takt time' represent in production planning?
Answer: The available production time divided by customer demand rate
Takt time (available production time ÷ customer demand) sets the production rhythm — the rate at which one unit must be completed to meet customer demand.
