Stop! Don’t Take That Part Off the Machine Yet!

Aug 25, 2016   //   by Bob Warfield   //   Blog, Manual, Manufacturing, Techniques  //  2 Comments
work stop for a kurt vise

Your g-code program has ended and all looks well with the part.  What’s your next move?
For most, the next move is to pull the part out of the machine and chuck up another blank to start machining the next part.  But, depending on how well debugged your manufacturing process is, and it isn’t very…

Keep Your Tools Safe With a New Tool Check-In Procedure

Aug 24, 2016   //   by Bob Warfield   //   Beginner, Blog, DIY CNC, Products, Techniques  //  2 Comments
Rust preventative

I like new toys as well as the next guy, so I try to take reasonable care of them. Towards that end, I’ve adopted a standardized “check-in” procedure for my shop. When a tool arrives, it is logged into an Excel spreadsheet. I have pages for tooling, consumables (cutters, abrasives, fluids, etc.), and stock (aluminum,…

7 Sweet Tricks and Setups for a Steam Engine Project

Stacked Part Fixturing

I get asked all the time by beginners, “How can I learn about fixturing?  How can I pick up all the neat tricks experienced machinists know?”
My answer is that encourage them to always be on the lookout–scrutinize every photo when they see a thread on a forum about some project to see what tricks…

Corner Rounding Endmills in G-Wizard Calculator

Aug 16, 2016   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, NewFeatures, Products, Software, Techniques  //  No Comments

With G-Wizard Calculator version 3.45, we now have support for Corner Rounding Endmills:

Corner Rounding Endmills: New Cutter Type
Corner Rounding Endmills are super-easy to use.  Just select them as a geometry type from the basic Endmill tool.  Be sure to enter the flute length (which is also the arc radius).  That’s all there is…

Straightness: Latest Chapter in Our Free GD&T Course

Surface Straightness

Surface Straightness controls the allowable deviation of a line on a surface such as this cylinder.
I just uploaded the latest installment in our Free GD&T (Geometric Dimensioning and Tolerancing) Course.  This one covers the Straightness Symbol, which can either be used to denote Surface Straightness or Axis Straightness.  Each one is different and has…

Here’s What the Right Digital Tooling Can Do For You

Aug 6, 2016   //   by Bob Warfield   //   Beginner, Blog, Products, Software, Techniques  //  No Comments

Have you invested in the right Digital Tooling for your CNC Work?
CNC and Manual Machinists are quite used to the idea of investing in tooling.  Many of us have never met a tooling gadget we didn’t covet, at least at first.  Sometimes, the right tooling can dramatically multiply your productivity or make possible things…

Total Beginner’s Guide to Feeds and Speeds

Aug 4, 2016   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, Techniques  //  No Comments
Surface Speed Definition

Have you been finding there’s too much jargon to even get started understanding Feeds and Speeds?  I’ve heard that from some folks.  I even added a Feeds and Speeds Glossary to the startup help that you get with our G-Wizard Feeds and Speeds Calculator.  But, there’s really no substitute for having a quick course that…

10 Specialized Work Stations to Keep Your Shop Organized

Aug 2, 2016   //   by Bob Warfield   //   Blog, Techniques  //  4 Comments

Sometimes centralization is great–I’ve got all my tools in one gigantic rolling cabinet so I always know where they are.  Except when I leave on laying where I used it last because I got distracted or forgot about it.
There’s an alternate theory of organization, one that believes not only that centralization needs to be…

Complete Guide to Structural Steel Sizes and Shapes Just Added

Aug 1, 2016   //   by Bob Warfield   //   Beginner, Blog, FeedsSpeeds, NewFeatures, Products, Software, Techniques  //  No Comments

I’ve just added our Complete Guide to Structural Steel Sizes and Shapes to our Calculator and Reference Data page.
Machinists and Fabricators often use these shapes so it’s handy to have access to this data.  It’s available both in reference chart form and as a free calculator built into G-Wizard:

Set Up G-Wizard for Small CNC Machines

Jul 29, 2016   //   by Bob Warfield   //   Beginner, Blog, CNC Router, DIY CNC, FeedsSpeeds, Products, Software, Techniques  //  8 Comments
Runout vs Tool Life

I get asked all the time how to set up G-Wizard Feeds and Speeds Calculator for small machines that aren’t very rigid.  Folks know intuitively (or after finding out the hard way) that these machines often can’t handle feeds and speeds that are as aggressive as other heavier machines.
G-Wizard has a well-designed set of…

Bolt Circle Calculator (Free)

Jul 25, 2016   //   by Bob Warfield   //   Beginner, Blog, GCode, Manual, NewFeatures, Products, Software, Techniques  //  No Comments

Yeah, I know, that “Free” on the end of that title looks a little cheezy, LOL.  What can I say, just trying to get the word out about an important new feature in our G-Wizard Calculator.  Believe it or not, it isn’t the Bolt Circle Calculator that’s important, although it’s cool.  It’s that we’re going…

New GD&T Lesson: Flatness

Jul 24, 2016   //   by Bob Warfield   //   Beginner, Blog, Techniques  //  No Comments
GD&T Flatness

The basics have all been laid out in our Free GD&T Course.  “GD&T” stands for “Geometric Dimensioning and Tolerancing”, which is an extremely useful standard for how to specify dimensions and tolerances on drawings–obviously something very useful for CNC’ers to know.
What’s left to finish the course is to write a lesson for each of…

Rockwell Hardness Tester

A Rockwell Hardness Tester…
I just finished uploading a new page for our Reference Charts and Calculators page.  It’s basically a Complete Guide to Hardness Measurement.  If you’ve spent much time poking around materials, especially steels, you will have come across hardness scales like Rockwell C, Brinell, or Vickers.  You probably wondered what all that…
