3D printing is a hot, new manufacturing technique. Its advantages are the ability to create nearly any shape, and to do so without any customized tools. In this blog post, I would like to show and inspire you how you can use 3D printing in lean manufacturing to make your production system even more efficient!
Lean Tools
Posts related to different lean tools, often also known as the lean toolbox. Different methods that can be used to improve the shop floor, although it is risky to use methods on their own without a whole lean system.
The Importance of ACT in the PDCA
The PDCA (Plan-Do-Check-Act) is one of the best-known lean methods, and one of the key philosophies for continuous improvement. However, despite its apparent simplicity, there are many struggles involved with its proper use. It seems that especially the Act part is challenging. Hence, let me dig deeper into why and how to Act in the PDCA.
SMED 2.0—A Changeover for the Changeover
Single Minute Exchange of Die (SMED) to reduce and shorten changeover times is one of the best-known methods in lean manufacturing. However, the original steps as shown by Shingo have, in my view, potential for improvement. Hence, I restructured the changeover workshop based on my experience with SMED to make it easier and more straightforward. This rework is not groundbreaking or revolutionary, but merely a few small changes to make it easier to use. As it is popular nowadays, I also added a 2.0 after SMED for my SMED 2.0.
Steps Toward One-Piece Flow
One-piece flow—while often defined differently—is one of the True Norths in lean manufacturing. Get your material flowing! In theory that is easy. In practice, however, there are many obstacles standing between where you are and where you want to be, also for one-piece flow.
What Should Be Your Target OEE?
It is common in industry to measure the utilization or the closely related OEE. It is a bit more difficult, however, to set targets for these KPI. Often you hear people wanting or demanding an OEE as high as possible, with a long-term target of ideally 100%. That is often problematic. The utilization or OEE is unfortunately not a clear cut target that you can simply maximize. Let me explain…
Examples of Job Shop to Flow Shop Conversions
I am a strong believer in the advantage of flow shops. To me, job shops are an inherently chaotic system. While there are ways to manage job shops, these are merely (more or less) successful attempts to put a Band-Aid on the chaos. To me, only a conversion to a flow shop will bring underlying stability. In this post I would like to give you both historic and current examples of successful conversions from a job shop to a flow shop.
What is One-Piece Flow?
In my last post I went into detail on the concept and philosophy of flow. This post goes deeper and looks at one-piece flow. If you are working in manufacturing, you surely must have heard the term one-piece flow. However, despite it being ubiquitous, I find that this is still often not very well understood. I also sometimes have the feeling that it is also used as a buzzword merely to impress others. Well, let’s have a look.
What Is Flow?
Everybody in lean talks about flow. You have to create flow! In particular you have to create one-piece flow. However, while this is true, I often find a lot of confusion on what flow means. Time for a post that goes to the basics and looks at what exactly flow is. My next post takes this up one step by looking at what one piece flow is.
