The aim of this diploma thesis is to propose a production technology of a given part based on technological and economic factors. At first it is found, if the part is producible by fineblanking. The theoretical part of the diploma thesis is concerned with the description of the conventional sheet metal cutting theory, fineblanking theory and bending theory. In the practical part of the diploma thesis, four variants of cut-in plan are dealt with including the selection of the optimal one based on technological and economic calculations. It is the production of a PULL REAR iron made of the steel sheet 11 320.21, thickness of 3 mm and a production run of 75 000 pieces per year.

Subject of diploma thesis is bending on technology production profile inflexion used for bearing construction industrial lifts, in work should be designed processing profile inclusive proposal tools and pressing machinery.

Master’s thesis fully fashioned within the frame of engineer study M-STM Manufacturing Technology and Management in Industry put literary study of bending technology. In the work is concept manufacture sidewall car for Fiat Ducato Valnik. Compare different technologies of manufacture press breaking, welding and casting. For the choose technology contains selection material, calculation parameters for project machinery and tools including of techno economic valorization.

This work describes the design of a dedicated three-rolls hydraulic bending for Hardox 500 without the possibility of bending sheet metal for the manufacture of pipes. The work will analyze the problem of proposed three-rolls bending, bending technology and creating of the pre-bending, the design of the adjusting hydraulic servo-cylinder, planetary gearboxes with hydraulic motors to drive the bottom rollers, a partial draft of the hydraulic circuit and the complete frame structure of bending machine with its covers.
