Graduation design is an important part of the teaching plan of higher vocational education and an important link to strengthen the combination of theory and practice.

Practice teaching is a compulsory course for all majors, which is carried out after students complete all professional courses and combine graduation practice. University life is coming to an end, and the last test and competition we will encounter is graduation design.

In this graduation project, my design topic is: NC milling process planning and design.

Due to the need of design, I carefully studied the parts drawings, but in the design process, due to lack of experience, I encountered many practical problems, which made me realize that the field internship research only proved whether I could do it well, not whether I could do it well. So I actively communicate with design instructors and operation instructors. With the full help and guidance of all the teachers, the problem was completely solved. At the same time, under the influence of the excellent work quality of all teachers, they have cultivated their own work style of being steady, seeking advice modestly, seeking truth from facts and being meticulous, and established a clear view of production, economy and overall situation, laying a good foundation for future work.

Through the graduation project, I really realized the importance of combining theory with practice. Through the comprehensive application of theoretical knowledge and practical operation knowledge, I cultivated my ability to rationally analyze problems and solve general technical engineering problems in practical work, so that I established a correct design idea, mastered the general procedures, norms and methods of process design, and further consolidated and deepened the absorption and application of the basic theoretical knowledge and basic operation skills I learned. In addition, I have improved my independent working ability in designing, calculating, drawing, compiling technical documents, compiling numerical control programs, operating numerical control machine tools, actually processing parts and correctly using technical materials, standards, manuals and other reference books, and also cultivated my innovative spirit and rigorous style of study and work.

Due to my limited ability and lack of design experience, design mistakes are inevitable. Please correct me and criticize me, so that I can find my own shortcomings in time and correct them so as to avoid them in my future work.

Here, I would like to express my sincere thanks to every teacher who gave me encouragement, guidance and help in this graduation project!
