Abstract:

The purpose of this project is to develop a pin router duplicator to accurately produce guitar bodies, necks, and fret boards. The pin router duplicator is designed to speed up production by reducing production time for the class Lean Manufacturing (MET 345), offered at Central Washington University. In the class, students learn how to work as a team to improve the way a woodshop is ran. The class is two hours long and only three guitar bodies are produced within that time frame. In order to test production times, the CNC router and the pin router duplicator will be used at the same time. The times will be recorded with a stop watch to produce guitar bodies, necks, and fret boards to see whether the pin router duplicator is going to produce more than the CNC machine. Accuracy and repeatability is also taken into consideration. With the use of the pin router duplicator, more than three guitar bodies will be produced in two hours, which will help with production goals. The methods that are used to arrive at the finished design are by using kinematics, stress, engineering, and static analysis. The final design that’s going to be used is a 4 bar linkage system. By using these methods, the necessary components for the 4 bar linkage system are designed.
