INSTRUMENTATION, EXPERIMENTATION, AND MAPPING TECHNIQUES FOR VIBRATIONS IN DRILLING

摘要

Currently, no models accurately predict dynamic tool forces and motion in drilling. A tool motion model can improve hole quality and cost by providing a method to improve machine and drill design. An experimental procedure to collect the force and displacement data to study drill motion will be presented. A visual approach of cutting tool forces, velocity, and motion provides insight into the physical behavior during drilling. This will aid in finding the relationship between dynamic cutting force, chip load, and velocity. This paper shows the experimental procedures and mapping techniques for a single tooth drill cutting aluminum tubes.
