We’re launching a new experimental service called the “CNC Question Exchange” here at the end of 2014. It’s a Question and Answer site designed to allow CNCCookbook readers to ask and get answers to their questions about CNC, Machining, and our Software.
I’ve been wanting to do a Q&A offering for some time. I’ve had…

Cimatron includes both the Cimatron CAD system and GibbsCAM. The transaction is expected to close in the first quarter of 2015. Both company’s boards have approved the transaction, but regulatory and shareholder approval are…
Here at CNCCookbook, we get visitors from all ends of the CNC spectrum–about 2.5 million of them a year. In all probability, we are the most popular pure CNC blog there is. I try to keep a balance on the content to keep the ends of that spectrum of visitors happy. That means we need…
Came across this neat project on Kickstarter in an email from the iBox 3D Printer people (who 3D printed one of these little tops):
Manufacturing the Foreverspin Top on a CNC Lathe
Optional Forever Base…
The best ideas are often the simplest. They’re easily grasped and can resonate with a large audience. By CNC’ing a…
Why should Job Shops and other Manufacturers work so hard to reduce inventory?
One of the central tenets of Lean Manufacturing is that if you reduce inventory, including Work In Progress inventory, you’ll reap savings that make for a much more profitable business. But what are those savings and how much more profitable can a…
Why do shops use multiple shifts?
It’s all about the economics. The thing to keep an eye on that drives these economics is plant and equipment utilization.
Let’s say you’re running a shop every day of every week, and you run it with 3 shifts so things are going 24 hours a day. Phew!
I’m sure it’s been a long hard period for Carbide3D but they’re finally ready to celebrate a major milestone–they’ve delivered the first Nomad CNC Mills.
Just to recap, Carbide3D had an extremely successful Kickstarter campaign that launched their company. We’ve written about their Apple-style vertical integration approach to making the world’s easiest CNC Mill before,…
Whether you’re trying to put together a Kickstarter project, launch a new product another way, or start a new business, it’s important to find some way of validating your idea before you get too much invested in it.

Periodically I pass along resources to help folks who are interested in starting or growing their businesses. I don’t do it often, because that’s not really the focus of CNCCookbook.

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…
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…
