Abstract by Jason Katrina

Abstract Statement: The purpose of this senior project is to create a jig that will enable a c-clamp to be locked in place while secondary machining processes can be performed. While it is held in place, a milling operation will be done to face the clamping surfaces. A separate bushing holder can be bolted onto the main mount so a hole can be drilled precisely on the threaded end of the c-clamp. To see this project through, it will require the use of engineering analysis techniques that have been learned in previous classes to find the forces applied to the c-clamp while it is held in place. The magnitude of the forces and dimensions of the C-clamp were used to develop the design of the fixture and drawn in Solidworks. After everything has been made to fit on the computer, raw material and hardware will be purchased to start the construction part of the project. The school has the necessary equipment to do all the machining operations needed for the project, so everything will be done on campus. The testing procedure involves putting the free end of the c-clamp under a pre-determined load in the x, y, and z-axes to test if the toggle clamps can hold it in place. The completed project meets all of the standards that were found in the analysis stage of the project and functions as originally envisioned.
