MEASUREMENT ADVANCED EXAM
QUESTIONS WITH CORRECT ANSWERS
100% VERIFIED.
1. In Statistical Process Control (SPC), what is the primary purpose of an R-chart?
A. To monitor the central tendency of a process over time.
B. To calculate the total yield of a production run.
C. To determine the number of defects per unit produced.
D. To track the range or variability within sub-groups of a process.
Answer: D
Conceptual Explanation: The R-chart (Range chart) is specifically designed to monitor
process variability by looking at the difference between the highest and lowest values in a
sample set.
2. Which of the following describes the ‘Cpk’ index in process capability analysis?
A. It accounts for both the process centering and the spread relative to specification limits.
B. It represents the total number of parts produced without defects.
C. It measures only how well the process is centered relative to the target.
D. It is the ratio of the process spread to the specification width, ignoring the mean.
,Answer: A
Conceptual Explanation: Cpk is a measure of process capability that considers both the
spread of the process and how close the process average is to the specification limits.
3. When using a micrometer, what is the purpose of the ratchet stop or friction thimble?
A. To ensure uniform pressure is applied to the workpiece for every measurement.
B. To allow for faster adjustment when measuring large parts.
C. To lock the spindle in place for easier reading.
D. To calibrate the zero point of the instrument.
Answer: A
Conceptual Explanation: Consistent measurement requires consistent pressure; the
ratchet stop prevents over-tightening and ensures repeatability between different users.
4. In the context of ISO 9000, what does the term ‘Traceability’ refer to?
A. The process of verifying that all employees have completed their safety training.
B. The speed at which a product can be delivered to the customer.
C. The ability to track a product’s history, application, or location through recorded
identifications.
D. The financial tracking of manufacturing costs per unit.
Answer: C
, Conceptual Explanation: Traceability is critical for quality control to identify the root
cause of failures by tracking materials and processes back to their origins.
5. A Pareto chart is most effective for which of the following tasks?
A. Identifying the relationship between two variables.
B. Mapping out the steps of a complex manufacturing process.
C. Prioritizing problems by identifying the most frequent causes of defects.
D. Predicting future production volumes based on historical data.
Answer: C
Conceptual Explanation: Pareto charts follow the 80/20 rule, helping teams focus on the
‘vital few’ problems that cause the majority of defects.
6. What is the standard tolerance for a dimension that does not have a specific tolerance
listed on a blueprint but is covered by a general note of +/- 0.005?
A. The machinist can choose a tolerance based on the tool being used.
B. 0.005 is applied to all dimensions regardless of scale.
C. The dimension is considered reference only and requires no inspection.
D. It depends on the number of decimal places in the dimension.
Answer: D
Conceptual Explanation: Standard title block tolerances usually specify different ranges
(e.g., .X, .XX, .XXX) depending on the precision indicated by the decimal places.
