Measurement of Production Overall Equipment Effectiveness
Žanda, Miroslav ; Novák, Josef (referee) ; Píška, Miroslav (advisor)
The diploma work deals with measurement of Production Overall Equipment Effectiveness in manufacturing company Alfa. Firstly, is processed the theoretical part concerning general production, TPM, lean manufacturing and OEE. After than is described the company, monitored device and technology used by the device. In the final section is evaluated the OEE for January, February and March; analyze downtimes, mistakes and losses and their solutions are proposed. The last chapter is devoted to the economic evaluation of the proposal.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.
