So far, when the thesis is completed, it has given me life enlightenment, enabling me to successfully complete my university studies. At the same time, I have also learned many useful life principles and clarified my life goals. I know what I want. I don't like to play as much as I used to be. After nearly half a year of design calculations, I found the design data of various CNC lathes for automatic loading and unloading robots. Finally, the thesis can be completed. I am very excited and happy. Although it is not the most perfect, it is not the best, but in my heart, it is what I cherish the most, because I have done my best to do it, it is my heart, made with sweat. Four years of study and life have not only enriched my knowledge, but also exercised my personal abilities. More importantly, I have unknowingly learned a lot of useful knowledge from the surrounding teachers and classmates. In this regard, I am sincere. Respect all those who care about me and help me, thank you.
