1. You are interviewing for an internship within a manufacturing engineering department where you will be responsible for designing multiple fixtures to aid in the manufacturing process. The senior engineer asks you to discuss two principles of design intent and how this will aid in you successfully completing the job 2. You are working for an engineering design firm where you are responsible for ensuring that all mechanical drawings meet the specifications outlined in ANSI Y14.5-2009 Dimensioning and Tolerancing Standard. Discuss items that you would be looking for on the mechanical drawings to ensure that the dimensioning rules are followed. 3. While inspecting the mechanical drawings of entry level employees, you must review the information provided on both assembly and individual component drawings. Explain what information you would expect to find in both types of drawings and how the information between the drawings relate the two to each other. Explain why providing this information is critical. 4. You are interviewing for a production engineering position within a manufacturing company that manufactures drivetrains for agricultural equipment. You are asked to describe two areas where technical standards would impact the design, manufacturing, or testing of the drivetrains and why it is necessary for such standards to exist. 5. In the same interview, you are asked to identify two types of gears, provide a practical application of each, and explain the technical information that one would need to include in a mechanical drawing to ensure the proper manufacturing of each type of gear 6. While designing a machine for a manufacturing company you have determined that you will need to apply a class 1 force fit between the drive shaft and a drive wheel, while applying a class 5 Running Sliding fit between the same shaft and a housing on the opposite e tolerances for both the hole and the shaft on each end of drive shaft if the nominal size is DIA..375 nd. Determine the

Explanation / Answer

1.) The Fixture should be sufficiently stiff to secure the present accuracy of machining to achieve perfect rigidity.

Clearance should be provided to the fixture body to allow for any variation in component sizes specially casting and forging. clearance should also be provided to allow for hand movements so that the work piece can easily placed in the fixture and removal after machining.
