We do not copy or retrieve any source of personal or corporate material without specific source. If there is any mistake we take full responsibility. Ho Chi Minh City, June 19, 2017 Confirmation of student: Truong Xuan Thai Le Minh Tai do an ACKNOWLEDGEMENT With each student of Mechanical Engineering, graduation project is important.
It could help them to improve, complete and know more about major knowledge. There for, we effectuated the project “Compose exercises on the 5-axis CNC machine for teaching CAD/CAM-CNC subject. After finishing this project, we will know more to accomplish and meet requirements of mechanical engineer. Firstly, we would like to say thanks Faculty of Mechanical Engineering for assigning this project for us.
This is challenge for us to study, ameliorate knowledge about mechanical. Secondly, we sincere thanks M.E Duong Thi Van Anh for supporting. She teaches us how to create G-code, load in CNC milling machine and operate it to processing components. She provides general CNC knowledge, which help us to do this project easier.
Nextly, we extend our thanks to M.E Dang Minh Phung. He is always beside us throughout processing this project. With his provision and support about mechanical, we could make this project better. Lastly, we want to send deeply thanks to teachers in Ho Chi Minh city University of Technology and Education, who has been teaching, communicating useful knowledge for us.
That is the basic foundation for our career in the future. Ho Chi Minh city, July 15th – 2017 Students perform Le Minh Tai Truong Xuan Thai do an ABSTRACTS Compose exercises on the 5-axis CNC machine for teaching CAD/CAM-CNC subject When technology and science are more and more development, CNC field create many tools, machines, equipment in responding to manufacturing and assembling. Many complex texture components are manufactured. Therefore, components are processed in 5-axis CNC milling machine, which are necessary.
This is reason why this project is researched. With project assignments, we have to perform processing some 3D, 4D and 5D components in 5-axis CNC milling machine to create model components and compose exercises for CAD/CAM/CNC subject. To respond project schedule, we had to study in documents about mechanic and CNC basic, which we were received from our lecturers. Addition to learning knowledge in Internet, books… we researched about 5-axis CNC milling machine current design.
At the same time, we learned how to operate and process in this machine. From that, we improved necessary parts, which couldn’t run 5 axis. When completed mechanic, we started to program G-code and load in CNC machine, ran simulation. If it had stability, we manufactured from workpieces to components.
After completing this project, we will have knowledge about designing machine, necessary skills about CNC machine such as operation, programming 5-axis G-code. We know how to improve a machine tools. However, the project has some limitations such as change tools automatically, machine spindle’s power is low, working area is narrow … So that, we hope the project to develop better by improving this disadvantages and to help the people who is learning, researching about 4,5-axis machine as well as how to processing 4D, 5D model. do an Table of Contents Chapter 1: OVERVIEW .1 The old version of the CNC machine .2 The necessity of this project .3 Scientific and practical significance .4 Researching object of the project .5 Researching object and scope.2 Researching specific methods.7 Technical and practical significance.
