Cutting force analysis when drilling with twist drill
Hon, Pavel ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
Theoretical part of this project contains basic characteristics of drilling technology, shows summary of drilling technologies and tools used for drilling, detailed description of twist drill, forces and loads analysis when drill, twist drill stress analysis. In experimental part of this project there are some investigations on twist drill geometry CZ001 made by company NASTROJE CZ, s.r.o. Cutting edge geometry and web thickness is measured on 3D scan of this drill and the results are compared to conventional products. Course of moment of cutting and course of thrust force is done by experiment where the recessed hole was drilled. Course of both loads is compared to long-term results on conventional drills. As application of the achieved results the cutting force position is calculated and stress and deformation analysis is performed.
