It’s fairly common to find machines that have multiple spindle options available. I don’t mean that you can specify multiple, options, but that there are actual multiple options delivered with the machine. A very simple example would be multiple pulley ratios. More exotic would be sub-spindles, for example a high-speed auxiliary spindle or speeder on…

Just launched my this month’s video with Cutting Tool Engineering for my “CNC Chef” column (a playful reference to the CNCCookbook). In the first video, I covered the subject of Tool Rubbing. It comes as a surprise to some that if you try to slow down a cut too much, it is actually much worse…
I just uploaded G-Wizard Calculator version 3.83. This is an optional release, PC only (not Mac), which means I won’t be turning on the auto-update right away. I do optional releases when I want folks who want the latest and greatest to check things out a bit before the mainstream gets hold of it. If…
Personalized service, advice, and mentorship is great. Having the hotel concierge advise you on the best place to find food you’ll like in a city that’s new to you can really make for a memorable dinner. Having a good friend who’s been doing CNC for their entire career and is a master can really help…
Machinists are familiar with spot drills–they’re stub length and have little or no flutes. These little drills are designed to be extremely rigid so that they can precisely spot a hole for a twist drill. Maximum meat in the shank keeps them on target. The goal is use the spot drill to make a little…
I am excited to announce that I’ll be doing a new monthly video series with Cutting Tool Engineering called the “CNC Chef” (a playful reference to the CNCCookbook). In our first video, I cover the subject of Tool Rubbing. It comes as a surprise to some that if you try to slow down a cut…
I wanted to let the Shopbot community know we’ve added some features to our G-Wizard Feeds and Speeds Calculator just for you. I have steadily heard two requests from the Shopbot users we already have:
#1: Give us pre-defined Shopbot Machine Profiles
#2: Give us the feedrates in inches (or mm) per second because that’s…
These days, it seems like Machine Learning is being talked about everywhere. Self-driving cars, machines beating humans at every game, Google search results change based on machine learning–artificial intelligence has become much more common that it was in the past.
There’s a reason for that: Machine Learning allows software to learn new tricks without requiring…
I just uploaded G-Wizard Calculator version 3.72 and it includes some very cool new capabilities.
Let’s start with something that every CNC’er deals with on virtually every new feature while using their CAM System:
What Feedrate Should I Use to Enter a Cut Using a Helix, Ramp, or Plunge?
Yup, CNC’ers deal with this quite…
I jumped about two feet when this plate broke loose from the vacuum fixture while the pocket floor was being machined:
He had actually dialed things back quite a bit to try to keep it happy, and I would have thought the majority of the worst cutting forces were done, but the part still broke…
Do you use cheat sheets?
You know, those little pieces of paper or charts where you cram in a quick summary of everything you need to know to solve some type of problem quickly. Man, I got through college on my cheat sheets!
Now hang on, before you start thinking I was actually cheating, our…
Nearly 1300 votes were cast for various endmill brands in our recent survey, and there were some 93 different end mill brands represented–WOW!
The response to the survey has been amazing, and now it’s time to present the results. I have divided those results into 3 tiers since there are so many brands to consider.…
What are the most popular end mill brands? Let’s find out by surveying our readers (click the link):

We’ll put up the results as soon as we get a decent number of responses. Be sure you’re signed up for our email newsletter so you don’t miss hearing the…
The depth of cut and width of cut (also called stepover) are crucial variables when milling pockets, profiling, facing, and any other machining operation where you’ll be cutting with the flutes on the side of an endmill. Aside from the machine’s capabilities, the material, and a description of the tool to be used, they’re the…
