Learn What the Angularity Symbol Means in GD&T Plus New Calculator

I just uploaded another installment to our Free GD&T Tutorial.

Angularity callout on a drawing…

Geometric Dimensioning and Tolerances is a methodical and scientific way to specify tolerances on your drawings.  It tells in a concise symbolic way how much your parts can deviate from the geometric ideal.  If you do much CNC work, you’re bound to come across a drawing with GD&T symbols on it sooner or later.  The good news is they’re not hard to understand and we’ve put together a quick mini-course to help you get up to speed.

One of the things I find about GD&T, is that if you’re a visual/spacial thinker, it makes more sense because the symbols have what’s called a “Tolerance Zone” that is an easy visual image to conjure up.  I find that very comforting.

The latest chapter in our course is on the Angularity Symbol, which is used to describe how surfaces and axes are oriented when angles come into play

Go ahead and try the free course.  It’s short and you’ll learn a lot quickly.  I recommend just going through it a chapter a day or so.  There’s also a quick reference guide to the symbols that’ll give you a quick idea of what’s going on and what’s possible.

The latest versions feature a neat quick reference guide to GD&T symbols that is built right into our G-Wizard Calculator:

The GD&T Quick Reference tells you what the symbols mean and link you through to the appropriate page in our mini-course if you want more depth.  There’s even a True Position Calculator:

That darned software is chock full of useful reference information not to mention having the best Feeds and Speeds Calculator available, and the best part is a lot of what’s there is FREE!

What?  What do you mean Free? That makes no sense!!!

Here’s the deal–it’s only the Feeds and Speeds features of GW Calculator that we charge for.  All the rest of it including the GD&T Reference and dozens of other handy calculators and references for CNC’ers are free.  All you have to do is take the free trial and it’s yours.

I can’t see how you go wrong with that.
