This task covers the design of the technological process of the governor casing. All key parts of the technological process are covered in this project, starting with the analysis from a structural and technological standpoint. After that we come to the choice of input material, where I decided to cast, since all other solutions were not economically viable. The concept of the technological process includes milling, drilling, twisting and threading operations. After that, in the detailed elaboration of the technological process, I calculated all the necessary processing parameters for each operation of the above operations. The development of technological documentation followed. In the end, I calculated the production and economic cutting speed for a single coarse and fine machining operation. In the preparation of this final paper, I approached the profession and became acquainted with many tasks that I will have to solve in my future job. Designing technological processes is a complex task, it involves a lot of time and even more effort, but it is necessary and highly valued. I find this a very interesting and I plan to study and improve in this direction.
