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…

Summary/Conclusion Discuss the strengths of your design and how it met the specifications. Discuss your assumptions and why they are valid. Discuss what you might change about your design in a redesign effort. Format: The project should be presented as a design report using a word processor. Include any hand calculations in an appendix. More details will be provided. Choose to design either a slip-jaw or channel-lock pliers to last for 25 years of use by a professional. Use an appropriate tool steel for the pliers. Design for 95% male grip force. Use a minimum factory of safety of 2.50. Determine dimensions not given. Slip Jaw Pliers A= 9.00 inches B=1.00 inches C= ? D=1.25 inches H= 1.875 Inches D B A
