Production of screw-thread in small engineering company.
Straka, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This work, wrought in branch of engineering technology in terms of baccalaureate studies, mentions the basic type partitioning of screw threads and their screw-threads labelling. There are presented some possibilities of screw threads manufacturing by chip-forming operation and by chipless machining operation, both with using of appropriate tools. Further the methods of production used in small machine-works are described. In this case the small machine-works is represented by secondary technical school.
List of Tool Materials in Forming Operations

The bachelor’s thesis elaborated within the scope of full-time study of specialization B-STI Mechanical Engineering is dealing with forming technologies and choice of tool steels for the production of forming tools. In the initial part of the work we are engaged in forming theoretical background, such as forming resists and shaping rules. Another section is devoted to tool steels and their most frequent heat treatment. In the following section of search is a basic description of the selected forming operations, including the use of machines and tools and highlight of the essential elements of the technology. Requirements for material of the tool are also listed there. The goal of this work is creating steel material sheet for cutting and extrusion tools and dies. These sheets are located in the attachment of this work.
