Equipment
Capability, condition, and calibration
Equipment questions test whether you know that capability must be demonstrated, condition maintained, and measuring devices calibrated. Categories to know: cutting (thermal, plasma, saw), forming (press brake, rolls), drilling and punching, welding (process, power source, positioning), material handling (cranes, magnets), coating application and surface preparation equipment, and inspection and testing instruments including dimensional tools, gauges, and NDT equipment.
Calibration is the central concept. Any device that produces a measurement used to accept or reject work must be calibrated on a defined interval, traceable to a recognized standard, with records retained and out-of-tolerance devices quarantined and their prior results evaluated. Equipment must also be fit for the work: a machine's capacity limit is a real constraint, and exceeding it is a nonconformance even if the part "looks fine."
Traps: assuming only lab instruments need calibration while shop tapes and gauges do not; assuming a machine can do work at the edge of its rated capacity; and forgetting preventive maintenance records as evidence of control.
Rule of thumb: if the tool's reading decides whether a part is accepted, it needs a calibration sticker, a current record, and a defined response when it is found out of tolerance.
