#1
Which of the following is NOT a common method of material inspection in manufacturing?
Magnetic resonance imaging
ExplanationMRI is primarily used in medical imaging, not material inspection.
#2
In material inspection, what does the acronym NDT stand for?
Non-Destructive Testing
ExplanationNDT involves testing materials without causing damage to them.
#3
What is the purpose of process inspection in manufacturing?
To ensure compliance with design specifications during manufacturing processes
ExplanationProcess inspection verifies adherence to specifications during production.
#4
Which of the following is NOT a common tool used in process inspection?
Oscilloscope
ExplanationOscilloscopes are not typically used for process inspection.
#5
Which of the following is NOT a common method of non-destructive testing (NDT)?
Destructive Interference Testing
ExplanationDestructive Interference Testing is not a recognized NDT method.
#6
What does the acronym MPI stand for in the context of material inspection?
Magnetic Particle Inspection
ExplanationMPI detects surface and near-surface defects using magnetic fields.
#7
Which of the following is NOT a common defect found during material inspection?
Homogeneity
ExplanationHomogeneity refers to uniformity, not a defect.
#8
What type of defect is characterized by small cavities or voids within a material?
Porosity
ExplanationPorosity results in small voids within the material.
#9
What does the acronym SPC stand for in the context of process inspection?
Statistical Process Control
ExplanationSPC involves using statistical methods to control processes.
#10
Which statistical tool is commonly used in process inspection to analyze variations in a process?
Pareto chart
ExplanationPareto charts help identify significant factors affecting a process.
#11
Which of the following is a common method used to detect surface cracks in materials?
Magnetic Particle Inspection
ExplanationMPI is effective in detecting surface cracks through magnetic attraction.
#12
What type of defect is characterized by foreign particles trapped within a material during its formation?
Inclusions
ExplanationInclusions are foreign particles embedded in the material during manufacturing.
#13
Which of the following inspection methods is typically used for detecting internal flaws in metal parts?
Ultrasonic testing
ExplanationUltrasonic waves penetrate the material, detecting internal flaws.
#14
What is the primary purpose of conducting failure analysis during maintenance?
To identify root causes of failures
ExplanationFailure analysis seeks to uncover underlying causes of malfunctions.
#15
Which of the following is NOT a common method of measuring dimensions in material inspection?
Tensile Testing
ExplanationTensile testing measures mechanical properties, not dimensions.
#16
What does the acronym CMM stand for in material inspection?
Coordinate Measuring Machine
ExplanationCMMs measure the geometry of objects using a probe attached to a moving arm.
#17
Which of the following inspection methods is typically used for detecting surface defects in metal parts?
Dye Penetrant Testing
ExplanationDye penetrant testing reveals surface defects by drawing penetrant into them.
