I get a lot of notes from beginners with very basic questions, and many of the questions boil down to needing to understand the jargon of CNC or needing to understanding how the pieces fit together. The vast majority of others need to get to the next level of detail and it’s not far out…
I had a customer ask me how to calculate Feeds and Speeds for Trochoidal Milling with G-Wizard Calculator the other day. G-Wizard is a perfect tool for finding these Feeds and Speeds, but first, what is Trochoidal Milling?
Trochoidal Milling is a High Speed Machining (HSM) technique that moves the tool in a shape called…
Geometry has a profound effect on your cutter’s health and well-being, not to mention your surface finish and material removal rates. Here is an Infographic that walks through 4 ways geometry can affect your machining along with what you can do about it in each case:…
There’s a minor release out, 2.49, that I’ve just uploaded. It primarily concerns adding some new materials:
– AR400 and AR500 abrasion resistant steel plate. Use this for buckets on excavators or it is also popular for making firearms targets.
– Hastelloy X: One of those solid green unobtanium super alloys. It’s a nickel alloy…
Recently a user of G-Wizard Calculator asked to understand better the difference between Calculator’s CADCAM Wizards and its Feeds and Speeds Calculator. It’s a fair question as they look totally different and the CADCAM Wizards are so unique nobody will have had experience with anything like them before they tried G-Wizard.
Let’s start with the…
An important concept that pops up from time to time is a CNC machine’s ability to accelerate. Acceleration is often the real limiting factor to the machine’s motion, more so than absolute rapids speeds, for example. In many real world g-code programs, the cutter may never get up to the commanded speed in some of…
It seems an unlikely combination, but when you’re an entrepreneur, anything is possible. Luke Colby’s company, Rocket Thermodynamix, makes parts for rockets. I’m talking about full-on beautifully machined aerospace quality components. Here is a typical example:
A pyrotechnic actuated poppet valve…
Yeah, I don’t know what you’d use one of these for either. Maybe Luke…
I just uploaded G-Wizard Calculator version 2.45. Release 2.45 fixes a couple of bugs to do with error messages and adds the new Crib Wizard to the Tool Crib page. The Crib Wizard is capable of automatically generating Tool Crib entries for endmills or twist drills in standard sizes. In addition, Tool Cribs now have…
So you’ve just gotten interested in CNC, and you notice the waters look a little deep. How do you get started?
Here are 6 things you should learn about first, before you buy a CNC machine, before you do anything else, just to get oriented and see what this CNC thing is all about. It…
I just uploaded GW Calculator version 2.4 to the install page. Lots of neat stuff in this release:
– Added Lathe Threading as a new Tool Type in Feeds/Speeds.
– Added a Threading CADCAM Wizard.
– Added the ability to transfer thread specs from the Thread Database to the Threading CADCAM Wizard.
– Added a…
I’m pleased to announce that FASTech, one of the Top 10 Mastercam dealers, is now offering G-Wizard Calculator to customers to help them with their Feeds and Speeds. These folks are a wonderful resource to the Mastercam community and are responsible for the eMastercam online community for Mastercam users. Their territory is Ohio and Eastern…
I’ve uploaded a couple of minor feature releases of GW Calculator lately and wanted to bring you up to speed on what new goodies are there. First thing is the latest release is GWC version 2.38 and it is available for download by clicking this link.
Now let’s go over what all is there:
I got a note from a customer who wanted to understand better why GW Calculator works the way it does with Cut Depth on Ballnosed endmills. Specifically, he had a cut where he wanted to enter the full diameter of the tool, but he was being limited to effective diameter, which was smaller. When depth…
I have just uploaded G-Wizard Calculator v2.36 to the install page. It adds two more CADCAM Wizards for lathes: ID Turning (boring) and Facing. CADCAM Wizards have three advantages over just using the basic Feeds and Speeds applet in GW Calculator:
1. They’re faster and simpler. You have to tell the CADCAM Wizards a lot…
I get mail with that kind of message every so often. A machinist uses G-Wizard Calculator and it gives them a higher feedrate, sometimes quite a bit higher, than his CAM software or other feeds and speeds calculators. The chipload is the same, and the formula to go from chipload to feedrate is simple, so…
