The following report illustrates the design steps to complete the hammer drill efficiency project. The main goal of the project is to provide a mathematical relationship between the variables that make up the hammer drill. Once established these relations will allow the designer to predict the rate at which holes may be drilled. This will be accomplished by completing a Design of Experiments (DOE) study. A DOE is a systematic way to carry out experiments to gather data about how varying each variable of the tool will affect the performance of the tool. The variables that will be studied are drill time, beats per minute, force on the tool, revolutions per minute, and cam geometry. After successful completion of the various experiments the designer will be able to predict how the tool will perform under various parameters.
