Lean Manufacturing for Job Shops: Lean Manufacturing Principles Part 8

Sep 17, 2014   //   by Bob Warfield   //   Beginner, Blog, Business, Manufacturing, Techniques  //  3 Comments
SayLeanAgain

This is Part 8 of our Introduction to Lean Manufacturing Principles Series.
With the first 7 installments of our series, you now have a pretty good overview of what Lean Manufacturing is all about.  I’ve gotten a lot of great compliments on the series, and I appreciate that.  But at the same time, I know there is a contingent out there wondering whether Lean Manufacturing is even the right thing to do for a Job Shop.  It’s very easy to look at Lean and conclude it’s only useful if you’re going to be making a whole lot of the same parts for a very long time.  … Read the rest

6 Ways G-Wizard Editor Can Save You Time and Money With G-Code

Sep 15, 2014   //   by Bob Warfield   //   Beginner, Blog, GCode, Software, Techniques  //  No Comments
DeepHoleWizard

CNCCookbook’s G-Wizard Editor is a full-featured g-code editor and simulator with loads of features.  But I want to call particular attention to these 6 Power Features because they have the potential for the biggest savings of time and therefore money when you’re dealing with g-code:
–  Hints and Information Tabs:  GWE will give you tons of information about your g-code that’s hard to impossible to get any other way.
–  Conversational Wizards:  Create g-code for common operations with simple point and shoot wizards.
–  Soft Limits:  Get alarms when your toolpath exceeds the limits you set.  Who couldn’t use a simple tool to help avoid many crashes?… Read the rest

The Ultimate Tony Stark Inspired Workshop, Part 2

LumbarChair

This is part 2 of our Ultimate Tony Stark Inspired Workshop Series.
Computers and design are a big part of Tony Stark’s Workshop.  Of course Tony has the robotic artificial intelligence J.A.R.V.I.S. to help him get things done, or perhaps mostly to clean up the shop and serve as a comic foil to Stark’s genius.  He’s got holograms and a variety of other things going on too that, like J.A.R.V.I.S, we’d be hard-pressed to come by–the tech simply isn’t available quite yet.  Fear not, there is plenty of awesome tech that is available for our Ultimate Workshop.
Computers Prefer A Darker Environment
First thing is, we need to house the CADCAM Design and Computer area in a darkened room.  … Read the rest

Kanban Visual Scheduling: Lean Manufacturing Principles Part 7

This is Part 7 of our Introduction to Lean Manufacturing Principles Series.
Kanban Came From Studying Supermarkets Stocking Food
Kanban, which means signboard or billboard in Japanese, is a visual scheduling system for lean and just in time production.  While some think of it as an inventory control system, it is more of a logistical chain control system.
Like so many Lean Manufacturing ideas, it was invented at Toyota.  It seems they had started studying the way supermarkets stocked their shelves with food just in time with an eye towards applying this to factory production lines.  Supermarkets do this to maintain freshness–there’s no use stocking more than just what  you expect to sell because otherwise the food spoils.  … Read the rest

Making G-Wizard Software Updates Faster and Simpler

Sep 9, 2014   //   by Bob Warfield   //   Blog, FeedsSpeeds, GCode, Products, Software  //  No Comments
NewImproved

Upgrading software is a fact of life.  Most of the time its a good thing–bugs get fixed and features get added.  At CNCCookbook, we try to keep everyone pretty up to date on the available releases for G-Wizard Calculator and G-Wizard Editor.  Most of the time, if a bug is discovered that escaped our testing, I can get a new release up before most people have encountered it.  If you’re proactive about keeping up to date, you’ll probably see very few of those bugs.
The downside of new releases is they’re a distraction from your work.  You have to stop, go find the download page, wait for the software to download, and then install the software.  … Read the rest

Results of Our Setup Sheet Survey

SetupSheetPages

As part of our post, “The Art of the Setup Sheet”, we ran a survey to see how shops were approaching their Setup Sheets.  Here are the results:
How Are Your Setup Sheets Delivered?
– 87% print them on paper
– 33% make them available on computer or tablet
Frankly, I was surprised and impressed to see such a high percentage online.
How Are Your Setup Sheets Created?
– 60% using office software such as MS Word or Excel
– 20% are handwritten on a standard form
– 20% are generated by CAM software
I was surprised here at the number that are still handwritten.  … Read the rest

The Ultimate Tony Stark Inspired Workshop, Part 1

StarksWorkshop

We’ve all seen photos of unbelievably spectacular garages filled with exotic cars.  Some of them are more like museums or theme parks than garages.  Jay Leno and Ralph Lauren both have amazing facilities of this kind.  But let’s say that in addition to having the time and wealth to do nearly anything you want, you’re also the type to get grease under his fingernails.  You know, the Tony Stark type:

Given that unlimited budget, this article series explores what sort of workshop you might create.  … Read the rest

Who is Afraid of Tool Deflection?

Sep 4, 2014   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Software, Techniques  //  No Comments
MillDeflect

Well, if you’re not afraid of tool deflection, you should be.  Here are 7 things to know about it:
1. Tool Deflection is bad for Tool Life
Tool Deflection is bad for Tool Life in several ways:
–  It’s actually forcing the tool to bend.  Like a paperclip, if you bend it back and forth too much, it will break.
–  If the tool bends more deeply into the cut, it can increase chipload to the point the tool breaks immediately.  Consider adding up the target chipload based on feeds and speeds, the runout, and the tool deflection to arrive at the true chipload the cutter will experience.  … Read the rest

SMED – Lean Manufacturing Setup Reduction: Lean Manufacturing Principles Part 6

Sep 1, 2014   //   by Bob Warfield   //   Beginner, Blog, Business, Manufacturing, Techniques  //  2 Comments
PitStop

This is Part 6 of our Introduction to Lean Manufacturing Principles Series.
The acronym “SMED” stands for “Single Minute Exchange of Dies”, which is quite a mouthful.  Wikipedia defines it as:
It provides a rapid and efficient way of converting a manufacturing process from running the current product to running the next product. This rapid changeover is key to reducing production lot sizes and thereby improving flow.
Let’s just think of it as reducing setup times and making the manufacturing environment more flexible so it can rapidly change from doing one thing to the next.  SMED is a particularly important concept for High-Mix + Low-Volume Shops, which is what most Job Shops are.  … Read the rest

The Art of the Setup Sheet

OnePageSetupSheet

Setup Sheets are an important part of everyday life in most machine shops.  They tell the operator how to set up the machine for a job.  Most Setup Sheets are intentionally kept simple, so they’re easy to create and easy to use.  For example, here’s a one page Setup Sheet that’s been done in Excel:

A simple one page Setup Sheet done in Excel.  Click the link to download a copy of the Excel file.
Many CAM programs can also be set up to generate Setup Sheets automatically as part of the post.  Often they create the setup sheets in HTML and they can be viewed or printed by your web browser.… Read the rest

Update on Carbide LLC and their Nomad CNC Mill

Aug 29, 2014   //   by Bob Warfield   //   Blog, Business, Cool, Manufacturing, Products  //  No Comments
Nomad

Recently I had a chance to catch up with Robert Grzesek, one of the founders of Carbide and also of the easy to use MeshCam CAM software. I wanted to get an update on the Nomad as well as some idea of what he’d learned from the whole Kickstarter process and manufacturing the Nomad.  For those who haven’t seen it, Nomad is a very cool vision for a CNC Mill that was a very successful Kickstarter campaign recently.  Be sure to check out our article on Nomad (that link just before this line) for more detail.  They raised a total of $513,665 against a goal of $30,000, so this campaign definitely knocked the ball right out of the park.… Read the rest

A Toolbox in New York’s Museum of Modern Art?

Aug 25, 2014   //   by Bob Warfield   //   Blog, Cool, Products  //  No Comments
TruscoToolbox1

Sure why not?  Many mechanical and functional things are beautiful.  This one certainly looks pretty snazzy to me:

It’s called a “Trusco” and you can find them on MoMA’s web store among other places.  The more generic term for them is “Cantilevered Tool Box,” and you’ll find a ton of copies all over the web searching via that name.  It was finding it on MoMA that got my attention, so I wanted to learn a bit more about its history.
The real Trusco’s were invented and are made in Japan from stamped steel.  The finish is enamel.  They’re popular and well known all over Japan, but not so much elsewhere, although I’ve seen them around a few times.  … Read the rest
