Abstract

In design and construction, various design tools are used, such as engineering design, making the designs to be more efficient with step-by-step processes. Then use tool named Function Analysis to find main function and secondary function of parts to be analyzed together with comparison table of strengths disadvantages in order to be used as specification in design of the sharpener. Which will be divided into two parts is the part that can be bought in the market is a grinder and grinding wheel of stone. Other part will be design is gripper and support gripper, which will be designed according to specifications, will design all 3 types to evaluate and then evaluated by a specialist by choosing the highest rated model to determine details in orders to created a sharpening machine for scissors design.As for testing of the sharpening machine, the constructor will use steel sheet size 5,6,7 and 8 inches which is length of scissors that the sharpener can create and sharpen and test steel sheet. This is at angles 10,20,30,40 and 50 degrees, which is angle used for sharpening scissors that cover the corners of both Convex and Bevel scissors. Verify the griddle secret by the measurement results of the test can sharpen scissors secret plates of any size any angle. For the experiment, the sharpening of scissors has been sharpened by the sharpening machine will be done by sharpening 5,6,7 and 8-inch scissors. At the actual angle of scissors and then using the sharpened scissors. Come to test the sharpness cutting 2 materials, hair and paper, the result of the test can sharpen the scissors of all sizes to be sharp until the two materials can be cut.
