Course: MET 465 - Geometric Dimensioning and Tolerancing Homework # 11 Instructor: Moustafa Moustafa Student Name : Gavin Cotton Chapter 19 – Krulikowski – Angularity Tolerance – Application Problem page 261: 1. Model the part and create 2D drawing. 2. The angularity tolerance labeled “D” requires that the surface must be within a 0. Mm wide tolerance zone that is: A. 45° relative to datum A only B. 4 ° relative to datum A and 90° relative to datum B C. ± 5° relative to datum A D. ± 5° relative to datum A and 90° relative to datum B 3. Which geometric tolerance could be used in place of the angularity tolerance labeled “A” that would result in the same requirement? A. Perpendicularity B. Parallelism C. Cylindricity D. None of the above.

What kind of things can you measure with them? https://www.grainger.com/search/machining/precision-measuring-tools/dial-indicators? tv_optin=true&searchQuery=dial+indicators&searchBar=true&suggestConfigId=6 a. They are devices consisting of a plunger and dial that are used to amplify variations within up/down movements on a surface. b. They can be used to measure deck clearance, crankshaft thrust and straightness, lifter travel, and other measurements that involve the distance between two surfaces. 5. Research about vision measurement systems and explain what they are used for https://shop.mitutoyo.eu/web/mitutoyo/en/mitutoyo/07/Vision%20Measuring%20Systems/ index.xhtml a. Non-contact scanning machines that scan 2D/3D objects for accurate edge detection and high accuracy measurements on shop floors or in other production environments. 6. Research about CMMs. What are they, what kind of software you need to have to operate them? https://shop.mitutoyo.eu/web/mitutoyo/en/mitutoyo/08/Coordinate%20Measuring %20Machines/index.xhtml a. a measuring device that measures the geometry of objects by establishing specific points on a physical surface using a contact probe. 7. What kind of tool would you use to measure angularity? See example bellow. Can you find any other way? a. Dial indicator a Angularity measurement result b Datum plane c Datum plane
