Uma contribuição ao conhecimento dos esforços de corte no processo de furação em cheio com brocas helicoidais

Abstract

This work presents a contribution to the knowledge of the machining forces in full drilling with twist drills. A literature survey of the State of art was mad e . A strain gauge dynamometer was projected and construed to measure the machining forces in drilling. Some national steels were identified and tested to obtain the machining forces. From which were obtained the coefficients of the mathematical equations used in calculation of the trust and torque in drilling.
