Using "reverse engineering" approach when making replica of Al casting by lost wax technology
Bezděk, Adam ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
The aim of this thesis was to produce a prototype casting of aluminum alloy with usage of reverse engineering technology. In a production process surface quality and dimensional accuracy was optimized. 3D scanning, FDM technology, ABSplus surface finishing possibilities and investment casting technology is introduced in theoretical part of this thesis. Practical part of the thesis includes description of original parts, their 3D scanning, usage of RE and RP, production of new castings and evaluation of their dimensional accuracy and surface roughness.

The design and technology of a mold production for the precision casting
Kopcík, Daniel ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The theoretical part of this bachelor´s thesis describes basic attributes of the lost wax casting method. The aforementioned section describes casting stages from component assignment to model casting, with the main concern of making wax model moulds, materials employed for moulding mixtures and casting accuracy achieved by precise casting. The experimental part begins with mould design for two components set by a customer, continues with focusing on design of casting and wax model mould. This is followed with creation of the CNC machine control program as well as choice of the moulding mixture and finally description of such casting. The experimental section is concluded by brief description of casting test and evaluation of the quality and accuracy of cast parts.
