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.
Detailed record
On the analysis of design, insertion and pull-out forces for selected orthopaedics implants.
 Ryšavá, Zdeňka ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
Target of this bachelor work is, on the basis of search and analysis of information, to prove a relation between insertion and pull-out work of surgical implants. The work deals with selected screw designs, insertion moment and and correlation between the pull-out work and insertion work. In conclusions we can say that the correlation exists.
