The master's thesis includes the development, analysis and technological preparation for making the connecting part according to drawing 050. The thesis describes the turning technology and its history of application. Improvements to lathes over time and important people who improved this technology are listed. The wider application of turning technology in various branches of mechanical engineering is described, and examples of application in individual sectors are given. The main parts of the lathe are described, and the division of lathes according to applications and modes of operation is indicated. The manufacturing principle itself is stated, and the movements that occur and which are the main processing parameters are described. Based on the analysis of drawing 050, the material from which the turned position is required is described, and the characteristics of the material and the specified application are described, Through the technological elaboration, all the steps and operations that need to go through from the initial bar to the raw material for turninga and all the way to the finished piece are described, and a conclusion is given based on the elaboration and examples.
