What if there was a Feeds and Speeds Calculator specially made for CNC Routers? What would it do differently?
As many of you have made abundantly clear in conversations we’ve had, CNC Routers need a bunch of things that are different than what other CNC’ers may need.
I used to constantly see CNC…
How big is a 2 x 4? The actual size of a 2 x 4 is about 1.5 by 3.5 inches. In fact, it might be up to 2/16″ less than that, depending on a some important factors.
Whoa! That’s crazy!
Now I’ve got to tell this story, just because I never knew and found…
I’ve been getting a fair bit of feedback about reference information lately. Turns out there is a ton of reference info built into G-Wizard that many people don’t know about, there’s a ton of info people would like to see me add, and there’s also a bunch of info that’s generally useful in tabular form…
I love it when you give me fabulous feedback that I can use to improve our software. The new Vacuum Fixture Mini-Calc was entirely inspired by just one conversation with someone who wasn’t even a customer–it was inspired by a problem that was preventing them from becoming a customer. This week I’ve just uploaded G-Wizard…
Arbors for small slitting saws plug directly into ER Collet chucks. Check our slitting saw page for more information…
I just seriously beefed up our Slitting Saw Feeds and Speeds page with a lot more information. I added information about Slitting Saw Arbors, more pictures, and a huge number of additional slitting saw tips and…
Do you use a vacuum table or vacuum fixtures?
If yes, then I know you’ve scrapped more than one part because it popped off the table due to too much cutting force breaking the vacuum. Wouldn’t it be great to have a quick and easy way to stop that from happening?
I get all my…
In Part 3 of our series on how to select the right CNC Cutter we’ll be talking about pocketing.
What are Pockets?
Pockets are cavities in the top of the part. Or, at least the face that’s on top during the milling process. They can have a floor, or they can be open by piercing…
Real Time Optimization: Part of My Evil Plans for World Domination!
I’ve just uploaded G-Wizard Calculator v3.26 and it includes Real Time Cut Width and Depth Optimization. Folks, let me tell you, Real Time is better than sharks with frickin’ lasers on their heads. I say that entirely tongue in cheek because a competitor has…
PCD Tooling such as these Guhdo endmills can really increase tool life when machining composites.
In part 2 of our series on machining composites we saw that composites can be incredibly abrasive and therefore quite tough on tool life. The most common way to get better tool life is to switch to PCD (poly-crystalline diamond)…
Sometimes we just need the job to go faster. When that’s the case, look into increasing your Material Removal Rates–MRR is your primary metric for reducing cycle time. I get calls all the time from shops that want me to help them reduce their cycle times, and these are the most useful features in G-Wizard…
What are the limits of Tool Deflection? Why? And is G-Wizard Calculator optimistic or conservative about those limits?
I recently finished several fairly in-depth discussions with folks running expensive production machining jobs about the limits of Tool Deflection and how to think about them. First, Tool Deflection is extremely important to Tool Life, Chatter, Surface…
This is Part 2 of our Composite Milling series. In Part 1, we talked about some of the general properties of composites.
Tooling for Composite Machining

One of the first factors that comes up in…
I just uploaded version 3.15 to the G-Wizard Calculator download page. It’s got a number of nice additions, but I am going to treat it as a Beta Test. By that I mean that I am not turning on the auto-update for it–I will wait for the next release and some feedback from users. So,…
SSV can really help control chatter when turning…
Hat tip to Tom for bringing this video to my attention. In it, Haas describes their “SSV” (Spindle Speed Variation) feature to control chatter. They also give the best discussion I’ve seen of how diameter affects surface speed when turning (smaller diameters have to run faster just…
Strange question, right? Almost nonsensical. Surface Speeds are surface speeds, and a difference of 700 SFM has got to result in a difference to the cutter–probably a BIG difference. Yet, paradoxically, there is reason to believe, backed by science, that 1000 SFM really can be just like 300 SFM in some cases during High Speed…
