CNCCookbooks Inc. says it invested a lot of time and effort into its "Complete Guide to CNC Mill Feeds and Speeds." It is one of a number of in-depth cookbooks the company offers to help you become a better CNC'er, and it was the first one it created.

The company has updated the guide to make it easier to navigate and find what you're looking for. It also did some overhauling to improve readability in some places.

The guide is not just about feeds and speeds–it serves as our guide to all things cutter-related, so there are articles there on everything from materials to specific cutters to coolant issues.

Here are some of the new changes:

• New guides for cutter types, including cutter specific guides for single-flute endmills, ballnose cutters, taps, twist drills, fly cutters, slitting saws, and a whole host of other cutter specific articles.
• New guides by material. This is a work in process, and there a lot more articles to do here, but guides with tips and techniques for specific materials are being added.
• New page template for improved readability of these guide pages. A lot of work remains to integrate this template throughout all the guides, but the plan is to go through every article revising and updating it to make them all the most complete and up-to-date information you can find anywhere on CNC feeds and speeds.
