This is Part 4 of our Introduction to Lean Manufacturing Principles Series. You can find the CNCCookbook home page for Lean Manufacturing here.
Value stream mapping is a lean-management method for analyzing the current state and designing a future state for the series of events that take a product or service from its beginning…
This is Part 3 of our Introduction to Lean Manufacturing Principles Series.
The Japanese word “Kaizen” is translated as “Good Change”, and that is exactly what Kaizen programs in Lean Manufacturing are all about. The word refers to any improvement, one-time or continuous, large or small, in the same sense as the English word “improvement”. …
Are you bemoaning the fact that you don’t have a 3D Printer but you’d like to have one of your designs 3D printed? 3DHubs will take your STL file, help you locate a nearby 3D Printer that’s part of their community, and pretty soon you’ll be off to visit the printer and get your part…
The results are in for our Manufacturing Competitiveness Survey, and they’re fascinating to say the least.
Here’s what we found out:
Are Shops Investing or Standing Pat?
Every single shop that participated in the survey is investing during the coming year.
What Specific Goals Are Shops Investing in Achieving?
Here’s what Shops are trying…
This is Part 2 of our Introduction to Lean Manufacturing Principles Series.
5S is all about the productivity implications of organization. A place for everything and everything in its place really matters if done with an eye towards manufacturing productivity.
The term “5S” derives from 5 Japanese words that all start with the letter “S”,…
Before there was metal, there was wood, at least in my shop. I didn’t get into CNC at that point in my life, many years ago, but I was way into custom cabinetry. I always admired the Japanese designs that required no fasteners–everything was held together through a cunning combination of tension and pegs. Someday…
I can already see from preliminary results of our Manufacturing Competitiveness Survey that there’s a lot of interest in Lean Manufacturing, so I thought I’d put together a multi-part series that introduces the guiding principles of Lean Manufacturing. I am also adding a Home Page for Lean Manufacturing to our CNC Manufacturing Cookbook.
We put together a survey that helps evaluate what shops are investing in to improve their competitiveness and why. If you are part of a CNC manufacturing operation, please tell us about your shop’s competitiveness plans. We’ll share the results soon when we’ve gotten enough responses so everyone can see the trends.
Take the Survey…
Every CNC machine user needs a way to get g-code programs onto their machines. Our recent DNC Survey was aimed at understanding how people are going about doing this. Here are the results:
Use DNC: 59%
Use Memory Cards, Direct Network Connection, or Other: 41%
This is not surprising. DNC is going to be more…
How does your shop go about getting g-code part programs on to the various CNC machines on your shop floor?
There’s the old stand bys–usb key, floppy disk, PCMCIA, and so forth. These involve plugging some sort of media into the machine temporarily to transfer the code. Newer machines can connect to your WiFi or…
VMC vs HMC axes…
I hear this question a lot: why would I choose a Horizontal Machining Center? Or, when is an HMC better than a VMC, I hardly ever see HMC’s?
Like so many things, the answer to these questions is complex. Let’s start by taking a look at how each one is laid…
One of the chief limitations of hobby scale 3D printing is its inability to print metal. Yes, there are commercial 3D printers that can print metal, even exotic metals like Inconel. But the cost of such 3D printers is prohibitive for all but the most high end applications.
What’s a poor 3D printing hobbyist to…
An important concept that pops up from time to time is a CNC machine’s ability to accelerate. Acceleration is often the real limiting factor to the machine’s motion, more so than absolute rapids speeds, for example. In many real world g-code programs, the cutter may never get up to the commanded speed in some of…
The pace of innovation for Desktop CNC has really been flying. First, 3D Printers rode the massive wave of hype and innovation. Expect to see the same with Desktop CNC Routers before too long, and that evolution is what we’re here to talk about today.
Let’s start by defining the term “Desktop CNC Router” also…
I must say, CNCCookbook’s new Rostock 3D Printer has attracted more attention from non-CNC friends across all age groups than any other thing CNCCookbook has done. Part of it is that there’s been an awful lot of hype around 3D Printing, but part of it is I show them an iPhone case made with the…
