Since the development of the industry, people no longer find it weird to include technical and technological advancements into manufacturing processes. Because of this, the automatic control technology sector is crucial to the growth of the industrial sector today.
One of the most crucial factors in making the global economy fully automated is control automation. Because of the use of automation technologies in industry, labor productivity has improved while manual labor has decreased. Additionally, using this application is the best option for producing high-quality goods at a lower cost, which encourages market competition. Our team decided on the graduation project topic " CNC laser engraving machine " with the help of the expertise, wisdom, and direction of our teachers.
The project "Building and controlling a CNC laser engraving machine" constructs a simple CNC machine with a laser with the following objectives: ∙ Apply knowledge, learn, design and manufacture CNC machine models. ∙ Program, control, and monitor CNC machine models to create high-precision products. ∙ Proficient in parameter setting and control on Mach3 software. ∙ Troubleshooting when encountering problems.
1 ACKNOWLEDGEMENTS Our team would like to thank the professors of the High-Quality Training Faculty, the Faculty of Electrical and Electronics Engineering, and the professors of Ho Chi Minh City University of Technology and Education for providing us with crucial information about our field of study during the four years of study from 2018 to 2022. We have oriented. capacity and understanding of with this crucial knowledge along with the process of detecting bad, learning more. As a result, the group was able to complete its graduation project, " Build and control CNC laser engraving machine" in addition to receiving supportive circumstances from the school and teachers.
We would want to express our gratitude to Mr. Nguyen Tu Duc, the tutor for our group's graduation project. Thanks to the teacher's direction and devoted instruction, particularly at those times when the group had trouble coming up with ideas or running into issues throughout the implementation phase, the project was successfully completed. Additionally, the team would like to express its gratitude to the other project groups for their assistance with the execution of their project.
In addition to the objectives that have been met, the team also unavoidably has deficiencies because of time restraints and the quantity of knowledge available; as a result, the team is anticipating many comments and recommendations from you. In order for the group to grow and improve this topic, teachers, seniors, and students are invited. From our group, sincere appreciation! 2 POSTER 3 CHAPTER 1: OVERVIEW 1.1 OVERVIEW Servo motors have played a crucial role in the motion control industry's revolution during the past few decades. Nowadays, servo motors have been continuously growing and are now found in practically all automatic control systems.
This development goes hand in hand with the rapid growth of industry around the world. The requirements for labor productivity and product quality, such as product precision, machine responsiveness, working speed, etc., increase as science and technology advance. The majority of automatic systems in factories today, including robotic arms, CNC machines, cranes, etc., employ servo motors to fulfill the aforementioned requirements. With benefits like fast rotation speed, large production torque, high accuracy, combined with a controller control and feedback (Encoder),.
the use of servo motors to control systems in the factory is becoming more and more common in order to meet the high requirements to serve the production process. In reality, we discover that human manual activities are incapable of doing tasks that demand absolute precision with the product's predefined locations. From there, using servo motors will simplify things. Our team chose on the topic of "CNC laser machine" because we wanted to learn more about servo motor control and do research on it.2 WHAT IS CNC? Computer Numerical Control is known as CNC (control of a computer system).
This is a system of automatic mechanical processing devices that operate on the premise of employing programs written in specialized symbols in accordance with EIA-274-D standards (often referred to as G-codes), to make it simple to grasp. The program must be loaded into the sophisticated computer system for the CNC machine to function. The computer is in charge of processing and managing several components of the machine, including the cutting head, cutting speed, cutting amplitude,. There are programs available for processing products.1 STRUCTURE AND WORKING PRINCIPLE Spindles can be one or multiple on CNC machines.
