The shift schedule runs from 06:45 to 15:15. A machine produces nothing during a 30-minute break or a separate 45-minute setup. It produces 12 parts per hour throughout the remaining time. What output should the production schedule allow for?
Correct answer: A - 87 parts
An inspector flags a hole because its diametrical position error is 0.18 mm. The drawing permits a diameter of 10.00-10.20 mm and specifies a diametrical position tolerance of 0.10 mm at maximum material condition (MMC). The actual hole diameter is 10.12 mm. No datum shift applies, and all other requirements are satisfied. How should the position result be assessed?
Correct answer: C - Accept; the permitted position error is 0.22 mm.
A bracket's inclined mounting face is foreshortened in the front and top views and appears edge-on in the right-side view. The drafter needs one added view showing the face in its true shape. Which choice accomplishes this?
Correct answer: B - An auxiliary view looking perpendicular to the inclined face
Before crawling beneath a raised hydraulic lift table to clear a jam, a technician locks out the pump disconnect. A gauge upstream of the closed load-holding valve reads zero. The table is still supported only hydraulically, and its approved mechanical maintenance support is not engaged. The technician is about to enter. What must happen first?
Correct answer: A - Prevent entry until the maintenance support is engaged and hazardous energy is controlled and verified.
“The machine is available-make another container so we do not lose utilization,” says a supervisor. The cell replenishes a full downstream buffer using production kanban cards; each returned card authorizes one container, and none has returned. Which response preserves the production system?
Correct answer: D - Wait for a returned production card before replenishing the buffer.
A capability study of a statistically stable, approximately normal shaft-diameter process reports Cp = 1.70 and Cpk = 0.78. Both indices use the same process data and two-sided specification limits. What limitation do these results identify?
Correct answer: D - The process is off-center; its capability is lower than the spread alone would suggest.
With energy isolation verified and both switch terminals disconnected, a technician obtains a lead-compensated closed-contact resistance of 8.0 ohms using a suitable meter. The meter beeps below 30 ohms; the switch specification permits no more than 0.2 ohm. How should the audible continuity indication be interpreted?
Correct answer: C - The contacts fail the resistance limit, although the continuity indication is working correctly.
In a hydraulic fixture, a sequence valve enables drill advance when clamp-line pressure reaches 600 psi. Investigation of a stopped cycle shows that the clamp jammed against an obstruction before contacting the workpiece. Pressure nevertheless exceeded 600 psi, and drill advance was enabled. What additional permissive would distinguish this jam from the required clamping condition?
Correct answer: A - Verify the specified clamp position as well as the required pressure.
During AC gas tungsten arc welding trials on aluminum, the balance control is increased. Its display explicitly shows percent electrode negative (%EN); current and all other settings remain unchanged. What paired effect should be expected?
Correct answer: B - Less oxide cleaning and less tungsten heating.
White parts trigger a diffuse photoelectric sensor, but otherwise identical matte-black parts do not. In controlled tests, both are held stationary at the same distance and angle. Supply voltage stays within specification. The PLC input always agrees with the sensor's output indicator, which remains off for the black part. Which diagnosis accounts for all these observations?
Correct answer: D - The black surface returns insufficient light to trigger the sensor.
