Education in mechanical design and control theory is paramount to anyone interested in engineering and the “Maker” culture. Additionally, integration of concepts normally presented in discrete learning segments enhances technical and intuitive understanding of how systems work individually and together. This project aims to increase students’ understanding of engineering topics while equipping them with the necessary tools and information to recreate a high-precision laser-cutting machine at a minimal cost. These topics include electronic designs, mechanical assemblies, machine calibration, and control theory. Although there is a wide range of laser-cutting machines currently available, most low-cost options are inaccurate and low-quality. Because such systems come preassembled and with little documentation, using them offers no educational value with respect to learning how the system functions. Since pre-assembled systems offer little hands-on learning potential related to their construction and design, the goal of this project is to develop a system that will offer this experience and enhance student understanding as they “Learn by Doing.” Students learning about the aforementioned topics will investigate them by constructing their own low-cost and reproducible laser-cutting machine. This system will enable students to study how to combine the ideas and theories learned throughout their engineering curriculum into a single design.

Theoretical Results

Vibration is one of the most important problems in laser cutting machine tool, which causes the manufacturing errors, also influences the machining accuracy of the parts. Modal analysis can calculate vibration type of structures. The paper presents how to use the powerful FEA software ANSYS to do the modal analysis on laser cutting machine tool and also studies the undamped free vibration on laser cutting machine tool. Finally, the test results and theoretical results were compared to verify the rationality of the modal, these provide theoretical base and conditions for dynamics analysis and optimal design.

Computer Numerical Controlled (CNC) laser cutting tools are developing as an alternative to conventional cutting systems thanks to increased accuracy, non-contact processing, higher productivity, less energy demand. An IR camera is utilized to monitor the laser cutting process of a steel plate. Even though the process is very complicated an analytical solution of the temperature field generated on a slab by a point source moving along one direction of the plate surface is provided in order to interpret the temperature field experimentally obtained by the IR camera.

Factors Of Influence

This paper presents the study of the influence of cutting parameters on surface quality in laser cutting of metallic materials. In this paper, it is shown which of the cutting parameters have the greatest influence on the quality of the processed surfaces by measuring various roughness parameters. After the experimental research was carried out a ranking of the factors of influence on the response functions was made, also graphs of dependency to various parameters of roughness were made.
