Title: MAKER: Design of a Virtual CNC Mill by Unity Software
It requires a lot of hands-on experience to learn how to operate a computer numerical control (CNC) mill. Virtual Reality (VR) can serve as a way to teach how to properly operate it. The goal of this research is to create a virtual CNC mill that can provide interactive training for students. The Unity software was used for this goal. Unity is a game development engine used to produce video games, utility software, and more. The functionality of the CNC simulation was created with C# scripting. The visual representation of the CNC mill was built through 3D modeling, and then transferred into FBX 3D models which are compatible with Unity. The virtual machine is able to take G-code inputs via either an input field or a text file. For the current version, it can simulate G00, G01, and G02/G03 commands and is able to cut sample workpieces per input. It also can save the coordinates of the cutting path via json file and use a python script to view its movement on a line graph. The virtual machine emulates the input commands very similar to the actual machine. This can serve as a good learning tool for CNC machine operators. The virtual machine created through Unity is proof that a digital simulation is achievable for the CNC machine. Future research will include implementing and incorporating mixed reality. Incorporating these kinds of technology will help a more immersive learning experience for students.  more » « less

  1. Engineering education aims to create a learning environment capable of developing vital engineering skill sets, preparing students to enter the workforce and succeed as future leaders. With all the rapid technological advancements, new engineering challenges continuously emerge, impeding the development of engineering skills. This insufficiency in developing the required skills resulted in high regression rates in students’ GPAs, resulting in industries reporting graduates’ unsatisfactory performance. From a pedagogical perspective, this problem is highly correlated with traditional learning methods that are inadequate for engaging students and improving their learning experience when adopted alone. Accordingly, educators have incorporated new learning methodologies to address the pre-defined problem and enhance the students’ learning experience. However, many of the currently adopted teaching methods still lack the potential to expose students to practical examples, and they are inefficient among engineering students, who tend to be active learners and prefer to use a variety of senses. To address this, our research team proposes integrating the technology of virtual reality (VR) into the laboratory work of engineering technology courses to improve the students’ learning experience and engagement. VR technology, an immersive high-tech media, was adopted to develop an interactive teaching module on hydraulic gripper designs in a VR construction-like environment. The module aims to expose engineering technology students to real-life applications by providing a more visceral experience than screen-based media through the generation of fully computer-simulated environments in which everything is digitized. This work presents the development and implementation of the VR construction lab module and the corresponding gripper designs. The virtual gripper models are developed using Oculus Virtual Reality (OVR) Metrics Tool for Unity, a Steam VR Overlay utility created to make visualizing the desktop in a VR setting simple and intuitive. The execution of the module comprises building the VR environment, designing and importing the gripper models, and creating a user-interface VR environment to visualize and interact with the model (gripper assembly/mechanism testing). Besides the visualization, manipulation, and interaction, the developed VR system allows for additional features like displaying technical information, guiding students throughout the assembly process, and other specialized options. Thus, the developed interactive VR module will serve as a perpetual mutable platform that can be readily adjusted to allow future add-ons to address future educational opportunities.

    Problem-solving focuses on defining and analyzing problems, then finding viable solutions through an iterative process that requires brainstorming and understanding of what is known and what is unknown in the problem space. With rapid changes of economic landscape in the United States, new types of jobs emerge when new industries are created. Employers report that problem-solving is the most important skill they are looking for in job applicants. However, there are major concerns about the lack of problem-solving skills in engineering students. This lack of problem-solving skills calls for an approach to measure and enhance these skills. In this research, we propose to understand and improve problem-solving skills in engineering education by integrating eye-tracking sensing with virtual reality (VR) manufacturing. First, we simulate a manufacturing system in a VR game environment that we call a VR learning factory. The VR learning factory is built in the Unity game engine with the HTC Vive VR system for navigation and motion tracking. The headset is custom-fitted with Tobii eye-tracking technology, allowing the system to identify the coordinates and objects that a user is looking at, at any given time during the simulation. In the environment, engineering students can see through the headset a virtual manufacturing environment composed of a series of workstations and are able to interact with workpieces in the virtual environment. For example, a student can pick up virtual plastic bricks and assemble them together using the wireless controller in hand. Second, engineering students are asked to design and assemble car toys that satisfy predefined customer requirements while minimizing the total cost of production. Third, data-driven models are developed to analyze eye-movement patterns of engineering students. For instance, problem-solving skills are measured by the extent to which the eye-movement patterns of engineering students are similar to the pattern of a subject matter expert (SME), an ideal person who sets the expert criterion for the car toy assembly process. Benchmark experiments are conducted with a comprehensive measure of performance metrics such as cycle time, the number of station switches, weight, price, and quality of car toys. Experimental results show that eye-tracking modeling is efficient and effective to measure problem-solving skills of engineering students. The proposed VR learning factory was integrated into undergraduate manufacturing courses to enhance student learning and problem-solving skills.

    This paper discusses the implementation of Industry 4.0 in an educational setting. Simulation, virtual reality, analytics, robotics and automation, and 3D printing are integrated to develop a small-scale production line for producing and inspecting 3D printed parts. The system consists of a robot and controller, programmable logic controller, 3D printer, machine vision system, conveyor belt, 3-phase motor and motor controller, webcam, PC and monitor, Raspberry Pi computer, pneumatic system, beam sensor, simulation software, and VR equipment. The system components are connected via ethernet cables running to a basic ethernet switch. An ethernet router is also connected to the switch to resolve IP connection attempts by the connected components. A mini CNC machine is used to drill holes on small metal parts that are assembled with 3D printed parts and plastic bricks to make a car toy. A robot is pre-programmed to perform the assembly of the car toy and a Cognex® camera is used to inspect the parts. Deep learning models are used to predict the remaining useful life of the drilling bits.

  4. A solid understanding of electromagnetic (E&M) theory is key to the education of electrical engineering students. However, these concepts are notoriously challenging for students to learn, due to the difficulty in grasping abstract concepts such as the electric force as an invisible force that is acting at a distance, or how electromagnetic radiation is permeating and propagating in space. Building physical intuition to manipulate these abstractions requires means to visualize them in a three-dimensional space. This project involves the development of 3D visualizations of abstract E&M concepts in Virtual Reality (VR), in an immersive, exploratory, and engaging environment. VR provides the means of exploration, to construct visuals and manipulable objects to represent knowledge. This leads to a constructivist way of learning, in the sense that students are allowed to build their own knowledge from meaningful experiences. In addition, the VR labs replace the cost of hands-on labs, by recreating the experiments and experiences on Virtual Reality platforms. The development of the VR labs for E&M courses involves four distinct phases: (I) Lab Design, (II) Experience Design, (III) Software Development, and (IV) User Testing. During phase I, the learning goals and possible outcomes are clearly defined, to provide context for the VR laboratory experience, and to identify possible technical constraints pertaining to the specific laboratory exercise. During stage II, the environment (the world) the player (user) will experience is designed, along with the foundational elements, such as ways of navigation, key actions, and immersion elements. During stage III, the software is generated as part of the course projects for the Virtual Reality course taught in the Computer Science Department at the same university, or as part of independent research projects involving engineering students. This reflects the strong educational impact of this project, as it allows students to contribute to the educational experiences of their peers. During phase IV, the VR experiences are played by different types of audiences that fit the player type. The team collects feedback and if needed, implements changes. The pilot VR Lab, introduced as an additional instructional tool for the E&M course during the Fall 2019, engaged over 100 students in the program, where in addition to the regular lectures, students attended one hour per week in the E&M VR lab. Student competencies around conceptual understanding of electromagnetism topics are measured via formative and summative assessments. To evaluate the effectiveness of VR learning, each lab is followed by a 10-minute multiple-choice test, designed to measure conceptual understanding of the various topics, rather than the ability to simply manipulate equations. This paper discusses the implementation and the pedagogy of the Virtual Reality laboratory experiences to visualize concepts in E&M, with examples for specific labs, as well as challenges, and student feedback with the new approach. We will also discuss the integration of the 3D visualizations into lab exercises, and the design of the student assessment tools used to assess the knowledge gain when the VR technology is employed.

  5. The development of inclusive leaders is essential for the success of future engineering and our nation. Equipping students with vital leadership-enabling competencies is necessary to develop a workforce that is prepared to act ethically, and responsibly, and tackle unforeseen challenges in the future. Inclusive leaders, or leaders that are self-aware, empathetic, and prioritize diversity, equity, and inclusion in their decision-making, are essential for the forward progress of engineering. A growing body of literature highlights the numerous ways in which students may develop leadership skills outside of the classroom through involvement in out-of-class activities (e.g., internships, clubs, sports, and research experiences). Research Experiences for Undergraduates (REUs) may provide students with a unique opportunity to develop leadership-enabling competencies that will prepare them for leadership in graduate school, the engineering industry, or academia. The goal of this research was to identify how students’ engagement in an engineering education virtual REU site contributed to their development of essential leadership-enabling competencies. The research question guiding this study was ‘What inclusive leadership-enabling competencies and skills did engineering students learn and develop during an engineering education Summer REU program?’ Qualitative data was collected via weekly open-ended surveys from 9 students (7 women, 2 men) participating in an REU over 9 weeks. Participants in this study consisted of students from underrepresented groups in engineering (e.g., Black, Latinx, women, students from low SES backgrounds, or first-generation students), attending large public research universities across the United States. This study implemented mixed methods to understand what leadership competencies were occurring most frequently and how students were learning and developing these competencies. A combination of text mining for frequency (quantitative analysis) and deductive and inductive coding (qualitative analysis) was used to analyze the data. A codebook was developed based on the leadership-coupled professional competencies that engineering industry leaders identified as essential for engineers entering the workforce. Researchers also allowed for other competencies and leadership-enabling skills to emerge from the data. Findings from this work indicate that students were developing a vast amount of inclusive leadership knowledge and skills from participating in the virtual REU site. This paper highlights, through the use of word clouds and text mining software, the many leadership-enabling competencies that participants developed throughout the summer research experience (e.g., learning, communication, adaptability, self-awareness, balance, networking, etc.). Further, students were able to develop digital literacy, increased communication skills, knowledge of career pathways, intrapersonal growth, and interpersonal relations. This work offers a novel contribution to the literature in understanding how students can develop technical engineering and research skills as well as professional and leadership skills in the same space. Findings from this work help to illuminate the benefits of this virtual REU site focused on engineering education research resulting in terms of developing inclusive leadership skills. Implications for future REU programs, students interested in developing leadership skills, engineering graduate programs, academia, and industry employers are outlined.
