Lean Manufacturing Techniques

Manufacturing Leaders Love Talking About Lean—But Who’s Actually Doing It? Everyone loves to talk about Lean. Lean principles. Lean thinking. Lean transformation. But when it’s time to make real changes—where does all that talk go? I’ve seen it too many times: A company maps its value stream, holds a big workshop, talks about reducing waste… and then? Nothing. The shop floor stays the same. Cycle times don’t improve. Bottlenecks remain bottlenecks. Why? Because real Lean isn’t about PowerPoint slides or whiteboard exercises. It’s about getting your hands dirty and fixing what’s broken. It means making practical, real-world changes—not just talking about them in meetings. Here’s what actually moves the needle: ✅ Cutting redundant inspections only where it makes sense, not blindly eliminating quality checks. ✅ Moving tools closer without disrupting ergonomics or safety. ✅ Automating material flow where volume justifies the investment, not just for the sake of automation. ✅ Reducing lead time by fixing scheduling bottlenecks, not just tweaking processes that aren’t the real problem. ✅ Managing inventory to avoid both excess and shortages, instead of forcing a one-size-fits-all JIT approach. ✅ Standardizing work only where it helps, while keeping flexibility where needed. ✅ Fixing quality at the source but making sure operators have the training to do it right. ✅ Empowering frontline workers with real authority to improve processes, not just asking for their “input.” ✅ Synchronizing production with demand without creating unrealistic targets that break the system. ✅ Using real-time data that’s actually useful for decision-making, not just flooding dashboards with numbers no one acts on. Lean isn’t about buzzwords. It’s about execution. The best manufacturers don’t just talk about Lean. They live it. They enforce it. They make it happen. They do VST (Value Stream Transformation), not just VSM! - If it’s not executed, it’s not Lean. ♻️Repost to lead real change!

The Power of SMED in Lean Manufacturing: Lessons from Formula 1 Pit Stops (1/2) In the fast-paced world of Formula 1 racing, every second counts. A mere delay of a few seconds in a pit stop can make the difference between winning and losing. This high-pressure environment has led to the development of highly efficient, synchronized processes that can teach us a lot about Lean manufacturing, particularly the SMED (Single-Minute Exchange of Dies) principle. Understanding SMED SMED is a Lean manufacturing technique that aims to reduce the time it takes to changeover or switch from one process to another. Developed by Shigeo Shingo, SMED focuses on minimizing downtime and increasing production flexibility. The goal is to perform changeovers in less than 10 minutes, hence the term "single-minute." Formula 1 Pit Stops: A Masterclass in SMED A Formula 1 pit stop is the epitome of precision and speed. In just a few seconds, a team of mechanics can refuel the car, change all four tires, and make necessary adjustments. Let's break down how these pit stops embody the SMED principles: 1. Preparation and Organization Before the race even begins, extensive preparation takes place. Tools and equipment are arranged in a precise manner, and every team member knows their exact role. Similarly, in SMED, the focus is on organizing tools and parts, ensuring everything is in place before the changeover begins. 2. Separation of Internal and External Activities In a pit stop, some tasks are performed while the car is still racing (external activities), such as preparing the tires and refueling equipment. Once the car arrives, the internal activities (changing tires, adjusting aerodynamics) are executed swiftly. SMED also emphasizes this separation, where preparatory work is done externally to minimize the time taken for the actual changeover. 3. Streamlining and Simplifying Tasks Every movement in a pit stop is choreographed to eliminate unnecessary actions. Each mechanic focuses on a specific task, reducing the overall time taken. This mirrors SMED's objective to streamline and simplify changeover tasks, ensuring that each step adds value and is performed as efficiently as possible. 4. Continuous Improvement Pit stop teams constantly analyze their performance, looking for ways to shave off precious milliseconds. This culture of continuous improvement is at the heart of SMED, where the process is regularly reviewed and refined to achieve faster and more efficient changeovers.

Secrets to <1hr setups ✅⚙️ "Hey I need #swisslathe parts but is small quantity ok?" 👈 This is a question customers ask a lot and thanks to #leanmanufacturing our setups are fast (often 20-30 mins) which means HMLV (high-mix, low-volume) projects are no big deal. Fyi, we don't even charge for setups when estimating = customer gets super low cost! Swiss Lathes are sort of notorious for tediuous, all day long setups because of the many adjustments which some say is an "art". While yes, tight tolerances and the nature of the sliding headstock can add complexity to cause lengthy setups... it doesn't have to be this way. Or at least you can greatly mininize it through #lean and #standardization methods. While too long to expand in detail, here are a few highlights of the Lean methods we use to keep Swiss setups to <1hr here at Acclaim Aerospace: 1) 5S Workplace Organization - the foundation for any lean system is critical. You can't have quick setups if you are walking all over the place looking for your tools, inserts, collets, etc with stuff in random drawers and misplaced. Organized and designated super easy to see tooling locations so that there "a place for everything and everything in it's place" 2) Standardizarion - since we mainly focus on harder to machine alloys, we pretty much have a standard tool list and have done a lot of testing to use same tools across the board. And then we designate certain stations on every machine for the specific tools from cutoff to profile & grooving insets to drill and boring bars. This makes programming and offset adjustments super fast at the machine since these tools are already in their stations and dialed in (example DCMT32.51 always in T3) or only need a quick swapout like a different size drill. 3) Quick Change Tooling - Standardizing locations helps a lot but sometimes you don't have enough stations for all the variety. That's where quick change tooling comes in handy. All of our stick tools use an interchangeable head, so that if you need to swap out a grooving head to a laydown thread insert... it's only a couple of seconds. This also means super fast replacement of a fresh insert when one wears out too. Having a spare head already set up with a fresh insert (think spare tires & rims at a NASCAR pit stop), you'll only have a few seconds of downtime as you swap the old and new heads. 4) Work Cells - For us we have multiple 20 and 32mm swiss lathes that all have standardized tooling which helps a lot, but we go a little further and try to dedicate certain machines to specific sizes -- meaning we run all the 1/8" diameter materials on a specific machine and it is always doing that. So many times there is *zero* setup, just load the new program and GO! Of course not everyone can just dedicate a machine to 1/4" diameter bar stock all the time, so maybe think about *range* of sizes like 1/4 to 3/8 or all common materials for example. Lots more but hope some of this is helpful 🤓👍
