A Creative Endeavor
At Pennsylvania College of Technology, a unique collaboration among faculty and staff has led to an innovative advancement in the automation and robotics lab. Customized frames for Siemens Human Machine Interfaces (HMIs) have been developed, enhancing both functionality and ergonomics for students engaged in automation studies.
These 3D-printed frames, emblazoned with the Penn College logo, elevate the HMIs to a 45-degree angle. This design change significantly improves accessibility for students in the Advanced Automation Software class, a crucial component for those pursuing a degree in automation engineering technology, particularly in mechatronics or robotics and automation.
The Role of HMIs in Automation
Human Machine Interfaces serve as essential links between operators and programmable logic controllers (PLCs). PLCs are vital components in automation, controlling machinery and processes in various industrial settings, from conveyor belts to HVAC systems. The HMIs allow users to interact with these PLCs through a touchscreen interface, enabling real-time monitoring and input.
Prior to the introduction of the new frames, the HMIs were left unprotected and positioned flat on lab benches, making them difficult to view and use effectively. The newly designed frames not only safeguard the devices but also ensure they are within the optimal line of sight for users.
Identifying the Need
Randall L. Moser, an assistant professor in electronics and computer engineering technology, recognized the necessity for improved HMI support. He approached Howard W. Troup, assistant professor and co-department head of automated manufacturing and machining, who initially crafted an aluminum prototype. However, as the project evolved, a more efficient solution was sought.
The idea of creating 20 aluminum frames posed significant challenges, including the labor-intensive process of welding and bending materials. This is where Luke J. Davies, an assistant professor of CNC machining and automation, entered the picture, suggesting 3D printing as a more practical alternative.
Embracing 3D Printing
Davies and Yorks collaborated using Autodesk Inventor, a 3D modeling software, to design the frames. Their design process was dynamic, involving extensive communication and rapid iterations. The initial design aimed for both functionality and aesthetics, incorporating Penn College branding and specific dimensions to ensure a perfect fit.
The final design featured hexagon blocks and the college’s logo, enhancing the visual appeal while serving a practical purpose. The design process exemplified creativity and teamwork, with a focus on achieving an ideal product that met educational needs.
Efficient Manufacturing Process
The manufacturing phase involved 3D printing four components for each frame: two end panels and two crossbars. Initially, the plan was to manually glue these parts together. However, Schaefer introduced a more sophisticated method by using a hot iron press to embed brass-threaded inserts into the plastic. This innovation ensured that the crossbars could be securely attached, leading to a sturdier final product.
The entire production process was completed within a week and at a cost of under $250, showcasing the efficiency of rapid prototyping.
The Value of Innovation
Rapid prototyping allowed the team to explore bold design ideas without incurring significant costs or delays. As Davies noted, this approach fosters innovation by enabling quick adjustments and experimentation.
The result of their efforts has not only improved the functionality of the lab but also impressed faculty and students alike. Moser expressed satisfaction with the design, highlighting the importance of showcasing Penn College’s capabilities to visiting vendors and potential partners.
Recognition and Impact
Siemens, a key partner and Corporate Tomorrow Maker for Penn College, plays an instrumental role in supporting technology education. Their involvement further emphasizes the importance of collaboration between academic institutions and industry leaders in preparing students for the workforce.
The initiative reflects Penn College’s commitment to providing hands-on, practical education that aligns with industry standards and expectations.
