Look Inside the Book

Every page has one big drawing and a box with the codes, numbers and steps you need to know:

These are real pages from the book. The table of contents is the full one: 9 parts and 64 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're standing at the control with a program on the screen, and the setup guy asks what line N40 is going to do. You see letters and numbers, and nothing tells you where to start.

The control manual covers it in pages of paragraphs: addresses, words, blocks, modal groups. It makes sense at the kitchen table. At the machine, it doesn't connect to anything.

G00 = rapid, may be a dogleg; G01 = straight line at feed F.

In the book, a program is one page: from % to M30, every part labeled, and what N, G, X, F, S, T and M mean, each one next to the line where it shows up.

Same with machine zero vs. work zero, G90 vs. G91, arcs with I and J, and SFM to RPM: each one gets its own page and its own drawing.

Next time someone points at a line, you read it, you know what the machine is about to do, and you don't go back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of text
  • Edge finding explained in words only
  • You walk up to the machine still unsure
To establish the X and Y work coordinates, the operator shall mount a mechanical edge finder in the spindle and rotate it at a speed generally between 800 and 1,200 RPM. The stylus is then brought into contact with the workpiece reference surface using handwheel increments of decreasing magnitude until the stylus displaces laterally. At that point, the spindle centerline is located at a distance equal to one half of the stylus diameter from the surface, a value that must be accounted for when the position is entered into the applicable work offset register.
FOR THIS
  • The edge finder in one drawing
  • The 0.100 in shift, and which way it goes, in a box
  • You see it and you get it

One Page, One Topic, All Clear

Think of it this way:

The vise is squared and the part is clamped. Now you need work zero, and the lead is busy on another machine.

You open the book to the edge finder page. The 0.200" tip, the moment it kicks, and the 0.100" that puts the spindle on the edge, all in one drawing, plus where that number goes in G54.

SFM = (π × D × RPM) ÷ 12: the edge speed, drawn as an unrolled ribbon.

Same with tool length offsets, geometry vs. wear, G81 vs. G83, and chip load to IPM: each one on its own page.

CNC Machining Illustrated is 9 parts and 64 topics, all drawn, and at the end the setup in 8 steps, every formula and code on one page, and 10 self-check questions with answers.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been running machines for years?

Yes. It doesn't teach you to cut metal; it shows where things live on a CNC: work zero, offsets, each line of a program, the speeds-and-feeds math. If you're moving from manual or from loading parts to doing setups, that's what it covers.

Where does the content come from?

From ASME Y14.5-2018 for drawings and tolerances, OSHA 29 CFR 1910.212 for machine guarding, and the NIMS Level I skill standards for CNC mill and lathe. The codes follow standard Fanuc-style G-code, and the book points out where controls differ so you check your own control's manual.

Is this official material?

No. It's an independent study book. It isn't issued or endorsed by any credentialing body, agency or machine or control manufacturer, and it doesn't come with a certificate or count toward one.

Does it replace my training program or shop training?

No. It's for studying and reviewing. It doesn't replace your program, your shop's training, OSHA rules or your machine's manual.

Are the practice questions the ones on the exam?

No. They're written for this book, to practice offsets, codes, arcs and speeds-and-feeds math, with every answer worked out. They aren't official questions from any exam or credential.

When and how do I get it?

As a PDF by email, at the address you enter at checkout. The 2 bonus books come with it.

Will it work with the control in my shop?

The codes follow standard Fanuc-style G-code, the kind most CNC mills and lathes in US shops read. Where controls commonly differ, like lathe code groups, peck retract and tapping, the book points it out so you check your own control's manual. Conversational programming isn't covered. One-time payment, no subscription.

Can I have it on paper?

Yes. It's a PDF you can print at home or at a print shop and keep next to the machine.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the control manual with nothing sticking.

Machine zero vs. work zero: you see it drawn and that's it.

You walk up to the machine knowing where every number lives.

Drawings make studying faster.
