[5/19/2020] No one has to tell machine shop owners and CNC machinists that it’s becoming increasingly more difficult to differentiate their operation amidst a manufacturing environment that’s experiencing a revolution based on evolving technology, new software, and increased connectivity. Add in changing consumer preferences and government policy, and it seems everyone in our industry is feeling the pressure almost daily! Most recently, the Coronavirus pandemic we are now facing down continues its spread around the world, meaning the months ahead for our nation’s economy and business will be quite volatile and dynamic. That means staying competitive in the local, national, and the global marketplace will require even more of a central focus on maximizing productivity and increasing efficiency as the United States reopens for business and restrictions are lifted.
This rings especially true for small and medium-sized operations, where the pain and uncertainty of COVID-19 is likely to be felt in a substantial manner, now and moving forward. To illustrate this point, a recent National Small Business Association member survey revealed that 80% of respondents have experienced reduced customer demand, and almost 50% are not confident in the future of their business. No doubt, the pandemic’s economic challenges are unparalleled, but we are already seeing light at the end of the tunnel. At Advanced Precision Machining, we are facing an operational slowdown, supply chain disruption, and reduced demand for precision manufactured parts, but we remain optimistic as we return to a sense of normalcy soon. We will continue to stake our reputation on meeting our clients’ needs for high-precision parts delivered on-spec and on-time, all while providing the best customer service experience in the machine shop business, even while social distancing.
With all of this in mind, APM’s CNC machine shop is still unable to match the production capabilities of larger rivals in low-mix, high-volume milling and machining work. In order to better maximize profits and achieve our desired growth goals moving forward in these uncertain times means we are consistently in search of ways to gain a competitive advantage. First and foremost, we can’t get ahead without the right technology in hand. Equipped with the latest in cutting-edge machine shop tools from suppliers such as Mitutoyo, Doall, Hurco, ProtoTRAK, Southwestern Industries, and Yama-Seki, we ensure our clients are completely satisfied with our work. But, this extends well beyond the right equipment and resources. There are always better ways of getting the job done!
This brings us back to what every machine shops’ focus should always center around; maximizing productivity and increasing efficiency. Enter the concept of lean manufacturing, the systematic practice for eliminating waste in the manufacturing process. As facilities around our country strive to resume normal business operations, “lean” will become ever more so important. But for smaller and mid-sized CNC machine shops, the methods central to lean production models don’t always lend themselves well to low-volume, high-mix, and oftentimes one-off precision machining environments. While true, many job shops have successfully adopted this methodology by focusing on the goals and strategies that are feasible to their particular operation. No matter what size, there is commonality in the desire and ability to incorporate some frequently described goals of lean manufacturing. These elements include: improving quality, eliminating waste, reducing time and effort, and reducing total costs. The core objective is to maximize value to the client while reducing waste in its various forms.
In a manufacturing environment, the 5S workplace organization method is central to the lean manufacturing philosophy. It is a system first utilized by the Japanese to reduce waste and optimize productivity by maintaining an orderly workplace, and it definitely has its place in smaller machine shops. In fact, a typical 5S implementation can reduce the square footage of space needed for existing operations. The 5S pillars of Sort (organization), Set in Order (orderliness), Shine (cleanliness), Standardize (standardized cleanup), and Sustain (discipline) are indeed scalable to any size facility and provide a template for organizing, cleaning, developing, and sustaining a productive work environment. In short, the transition to lean production should not focus solely on equipment, but instead, with the procedures associated with how existing equipment is used.
This begins with a focus on streamlining various processes, and there are many to choose from on the typical precision CNC machining floor. The key is being flexible and adaptable both to the working environment and to the demands of customers. Here is just a small sampling of some possible improvements:
Just a sampling to be sure, and what we’ve highlighted is not an end itself, but a means to more streamlined operations by maximizing productivity and increasing efficiency. This will become more and more important as businesses ramp up and the economy hopefully rebounds. Lean is more than simply some best practices, it’s about doing more with less and removing impediments to productivity. By not implementing at least a few lean practices, a machine shop loses its competitive advantage, and future growth, if so desired, will be stymied.
As we continue to fight this pandemic together, all of us at APM wish you, and those close to you, continued good health, safety, and optimism!
