Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…

Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
