Here at CNCCookbook, we do extremely in-depth research on our articles.  We want to be sure that when we publish a guide to something, we’ve done as much of the work for you as possible.  We’re pretty good at it, or we wouldn’t see 4.5 million CNC’ers visiting our site every year–roughly the same as much bigger CNC companies like Haas CNC!

But we don’t rest on our laurels either.  I go back and update key pages on a regular basis.   This week, I just did a major upgrade to our Micromachining Guide.

The Guide was already comprehensive, but after spending a full day researching the latest new information on the topic, I made a ton of updates:

  • I added an application section where you’ll earn what industries use micromachining and a little bit about why.
  • Added a section detailing the 4 major factors that cause micromachining tooling to be much more likely to break.
  • Added a ton of additional information about runout in micromachining applications–the #1 issue to look into when you’re having micromachining tool life issues.
  • Took the original 10 Tips for Minimizing Breakage of Micro-Mills to almost double–there are now 17 Tips for Minimizing Breakage.
  • There’s new information on selecting the optimal number of flutes for your application.  Everything changes with micromachining, and it’s not as simple as 2 or 3 for aluminum and 4 or more for everything else.
  • Added extensive information on the runout limitations of different collet systems.  Yes, it really does matter for these tiny tools!
  • Went into some detail on the effects of vibration on micromachining.  Also added some very special considerations for avoiding chatter in these applications.  Chatter can mean almost instant death to delicate micro-cutters.
  • I describe a very delicate but important setup issue for micro-turning applications that most will not even know about.
  • Completely updated, rewrote, and added a lot of new material on CADCAM considerations for micromachining.
  • Added a new section to help you understand your spindle rpm needs for micromachining.
  • There’s a killer new tip for how to spot drill to improve the life of your micro-drills.

There are tons of links to other sites in the article should you wish to research any of the results in more detail on your own too.  All in all, you couldn’t ask for a more complete guide on micromachining anywhere.   I certainly couldn’t find one in my research which involved going through hundreds of Google search results.
