In 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 is detected
An out-of-control signal occurs when points exceed 3-sigma limits or when non-random patterns (runs, trends) indicate special cause variation.
Which turning operation produces an internal cylindrical surface?
Answer: Boring
Boring uses a single-point tool to enlarge or finish an existing hole, producing an accurate internal cylindrical surface.
What is the primary function of a fixture in a manufacturing setup?
Answer: Locating and clamping the workpiece accurately and repeatably during machining
A fixture holds the workpiece in a precise, repeatable position and orientation relative to the cutting tool, ensuring dimensional consistency across multiple parts.
In powder metallurgy, the green compact's density is primarily controlled by:
Answer: Compaction pressure applied during pressing
Higher compaction pressure reduces porosity and increases green density by mechanically deforming and interlocking powder particles before sintering.
Which of the following best describes the function of a transfer line in mass production?
Answer: A series of dedicated stations performing sequential operations automatically on moving workpieces
A transfer line automatically moves workpieces through a fixed sequence of machining stations, enabling high-volume production of identical parts with minimal manual intervention.
In abrasive waterjet (AWJ) machining, the role of the abrasive particles is to:
Answer: Erode material through high-velocity impact and micro-cutting
Abrasive particles entrained in the high-velocity water jet impact and micro-cut the workpiece surface, enabling machining of hard materials like titanium and ceramics.
What is the main purpose of normalizing a steel component after forging?
Answer: Relieving residual stresses and refining grain structure for uniform properties
Normalizing involves heating above the upper critical temperature and air cooling, which refines the coarse forged grain structure and homogenizes mechanical properties.
