Optimization and use of standardized manufacturing routines for the Common Rail Flange production of high pressure pumps.
Doležal, Jan ; Prokop, Jaroslav (referee) ; Píška, Miroslav (advisor)
Objective of the Project of optimization and introduction of standardized procedures in flange production is to plan, determine and introduce optimal procedures based on time scan and MTM analysis; to determine standards, to establish standardized procedures for multi -machine operation and visual control and to train personnel according to new procedure. Project is expected to stabilize process, decrease work in process production, improve quality and increase volume of flange production to 2200 pieces per day for one production line. Furthermore to provide comparison of standardization influence on operations in flange production process, to perform quantitative analysis of several working instructions on visual control workplaces by statistics method (R&R study).

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.
