7.
For Experiment, please include:
• Comment on one (1) error
• Comment on the accuracy of one (1) measurement method of a specified feature
• Provide an alternative method for the item above
• Analysis of measurement (hole data)
• Analysis of measurement (Recommendation)
CONCLUSIONS:
This section is reserved for an explanation of why you observed what you did.
1. Perform the following steps to analyze the accuracy of the measurements.
A. Use the chart to compare the measured hole diameter data collected with each tool.
B. Analyze the data, then rank the tools in order of which one is the most accurate to least accurate. Do this based on which one comes closest to measuring the true diameter.
C. Why did each tool rank where it did?
Analysis of Measurement (Recommendations)
2. The following steps present you with four different situations. You are required to select the best-suited measuring tool for the measurement.
A. Which tool from your lab kit would be best suited for measuring the length of the slot? Explain your answer.
B. Which tool that you used from your lab kit was best suited for measuring the thickness of the part? Explain your answer.
C. Which tool or process would you recommend for measuring the length of the specimen if an accuracy of 0.002" was required? You are not required to select a specific tool from your lab kit. Explain your answer.
D. Which tool or process would you recommend for measuring the angle of the slot if an accuracy of 5' was required? You are not required to select a specific tool from your lab kit. Explain your answer.
