A CNC machinist math cheat sheet covers the formulas you actually use: speeds and feeds, basic trig, and bolt circles. Here is what to include and the real limit.
The ProtoTRAK is mainly conversational, but it uses standard M-codes for the spindle, tool change, coolant, and program stops. Here are the common ones and what they do.
A G-code mouse pad keeps the common codes under your hand all day. Here is what to fit on the limited space, how to design one that lasts, and its real limit.
A 4K M-code wallpaper keeps the common machine codes on screen all day. Here is what to include, how to design one that stays readable, and its one real limit.
A wall poster of the common G and M codes is a great quick reference. Here is what to put on it, how to format it to read from a few feet, and its one real limit.
A G-code lock-screen wallpaper is a fine pocket reference and a poor teacher: what belongs on it, how to make one that is actually readable, and the limit.
No universal Haas speeds and feeds chart exists, because cutting data belongs to the tool and material, not the machine brand. Two formulas replace the PDF.
LNC controls run a Fanuc-shaped G-code dialect: the universal core is safe to trust, while cycles and builder M-codes belong to your machine's manual.
No single app does machinist math and G-code lookup well, and the lookup half is the wrong goal anyway. The pocket stack that covers both, free.
The machinist wallpaper carries numbers, not codes: the two cutting formulas, tap-drill pairs you actually use, and decimal equivalents, sized for a glance.
The Fanuc VMC code list worth printing is one page: the standard G and M cores, the G43 habit, blank lines for your machine's codes, and a provenance rule.
Tormach publishes the full PathPilot G-code list free. Here it is mapped by family, with the lathe G7 rule, the LinuxCNC-shaped dialect, and Fanuc checkpoints.
A badge buddy holds about twenty codes legibly. Here is the exact front and back worth printing, the sizing specs, and when to retire the card on purpose.
A wood router's working M-codes are a short list: M3/M5 spindle, M0 pause, M2/M30 end, and the coolant pair M8/M9, usually rewired to dust collection or air.
G-codes control how the machine moves and M-codes control machine actions like the spindle and coolant. Here is the real difference and how they work together.
M06 executes a tool change while the T word selects the tool. Here is how T6 M06 works, the safe sequence around it, and why G43 always follows.
The core G-code and M-code a TESDA CNC exam expects you to know: motion, units, positioning, spindle, coolant, and program control. A focused study list.
Pocket reference apps are great for looking things up. If your goal is to memorize G-code, a recall-practice app is a different and complementary tool. Here is the distinction.
A reference app looks codes up; recall practice means you do not have to. Here is the difference, and why beginners are better served by drilling than by another lookup app.
A short reference list of the G-codes that show up in almost every CNC program, with a one-line meaning for each, built for beginners.
A short reference of the M-codes you will meet first: spindle, coolant, tool change, and program control, each with a plain-language meaning.
