One of my favorite things about working in the manufacturing industry, and specifically in industrial automation, is the opportunity to visit factories across the country and learn how things are made. As an engineer working to help others leverage robotics and automation to improve their processes, I sometimes find my day-to-day experience is like being on the set of the TV show, “How It’s Made.” Recently, most of my conversations with manufacturing engineers and plant managers originate from a common observation: “Our production teams are stretched thin, and we would like to utilize some form of automation to help keep up with demand.”
Most often, the manufacturing engineers already have a sense of where they want to utilize robots within their facility. Many can readily describe the ideal applications and likely candidates, namely those that pose safety risks, are highly repetitive, labor intensive or too slow.
Despite high awareness, many automation projects struggle to get off the ground. To help assuage apprehension, I often encourage teams I work with to keep the following top of mind as they consider embarking on their automation journey.
Dream Big, but Start Small
Deploying automation is often a multiyear process. For manufacturing engineers tasked with delivering on a broad Industry-4.0 mandate, it can be daunting to know where to begin. Almost always, the best first step is to start small and deliver a quick win. Picking an “easy” robotic application that immediately solves a pain point, no matter how big or small, is critical to building momentum and allows the organization to learn.
Clearly Define the Metric for Success
Another good starting point for any automation idea is to first quantify the impact. What is the KPI that automation will improve? Ultimately, all robotic projects should deliver a quantifiable improvement toward the overall site goals. Defining the parameters and expectations in advance of scoping the projects can help prioritize opportunities and level-set in internal funding reviews.
Simplify, Then Automate
A common challenge for robotic projects is variation. Some teams spend weeks investigating projects only to find that, in the end, the idea is too costly to automate due to the high number of variants. Other times, teams will de-prioritize potentially great ideas too early because an initial survey deems the sequence of operations too complex. However, many perceived challenges to automation can be solved by looking upstream. Are there elements of the product design that can be changed to improve manufacturability? Can prior manufacturing steps be modified to make robotic applications downstream easier? Before trying to automate a suboptimal and unnecessarily complex process as-is, look for ways to simplify in-station and upstream.
Many robotic projects rely on integrator partners to support the engineering, sourcing and implementation activities. When external vendors are involved, there is an information asymmetry between the two parties. This can manifest in many ways, but a common symptom is an inaccurate scope of work, which leads to risk for all parties. To mitigate the concerns, it is helpful for all parties to recognize both teams are learning as the project evolves. Striving for transparency throughout the quoting, design and engineering processes helps eliminate surprises for all and ensures the group’s collective success.
Plan for Change
As companies assess opportunities to deploy automation, it is helpful to analyze change through multiple lenses. The most intuitive lens often focuses on the manufacturing process itself. For example, many companies have line of sight into future model changes and can account for flexibility during the design phase. However, it is also important to view the automation through a wider lens. How does the automated work cell change upstream or downstream processes? How are day-to-day roles for operators affected? What type of training programs should be created?
While not exhaustive, thinking through the above can help engineers assess automation projects from multiple points of view. Ultimately, I am excited to see how advances in technology, in the field of robotics and more broadly within our industrial manufacturing industry, will unfold. As companies continue to embrace automation, robotics or other novel manufacturing processes, I look forward to helping create the next era of “How It’s Made.”

SME and Rapid News Publications Ltd Renew Partnership on RAPID + TCT Event
SME and owner of the TCT Group, Rapid News Publications Ltd, recently announced a renewal of the strategic alliance that will see the organizations continue to produce the annual RAPID + TCT 3D-manufacturing event in North America. The two organizations have co-produced the industry-leading event since 2017, combining over three decades each of insights and experience in accelerating the adoption and advancement of 3D-manufacturing technologies. The partnership will continue to leverage SME and TCT’s collective industry knowledge, global networks as well as several key strategic industry partnerships to take RAPID + TCT to the next level in the coming years, cementing the event’s position as the largest and most-influential additive manufacturing event in North America. Emerging technologies such as additive manufacturing (3D-printing) and other 3D-technologies are enabling manufacturers to reduce time to market, produce stronger and lighter parts, improve efficiency, reduce waste, cost and emissions, and create products and geometries they could not create before. Increased awareness of these real benefits of using advanced manufacturing technologies will encourage more companies to adopt these technologies, which will improve their ability to compete on the global stage. The next edition of RAPID + TCT takes place May 17-19 at Huntingdon Place in Detroit. To learn more and to register to attend, please visit rapid3devent.com.
