The baccalaureus thesis includes the analysis and design of the technological process of making the extension catcher according to the drawing 10 - 20 - 50. Through the design of the technological process it is described the importance of planning and organizing the production. First, the technical drawing of the extension cather was analyzed, the dimensions, tolerances, required manufacturing accuracy, as well as the required materials were analyzed. After that, as part of the design of the technological process of production, the order of the technology of operations and interventions is determined, as well as the machines on which the processing is performed. Manufacturing technology includes all technological operations that take place from the starting material to the finished product. Manufacturing technology must be high quality, efficient and economically acceptable due to competition in the market. Thesis projects the creation of a working position, selects tools and machines for processing and makes a calculation of production. The calculation of production provides approximate values of processing time, which enable the preparation of an offer to the customer and the planning of production time.
