The G-code a NIMS CNC milling credential expects is the standard mill set: motion, plane and units, offsets, compensation, and basic canned cycles. Here is the list to study.
A setup-focused interview often moves to the machine: explain a program, set an offset, talk through a tool change. Here is how it tends to flow and how to prepare.
A G00 rapid moves at full speed, so a wrong offset, tool length, or start point turns a small mistake into a crash. Here are the usual causes, explained for learners.
Many shops do test your code knowledge when hiring, through a short quiz, a program to read, or questions at the machine. Here is what to expect and how to be ready.
WorldSkills CNC turning is elite, time-pressured, and precision-driven. Here is how to practice in that style, even without official past papers to copy.
A Z-axis plunge crash usually comes from a rapid into the part, a wrong tool length offset, or a missing retract. Here are the code mistakes behind it, for learners.
A practice-first plan for memorizing the G-code and M-code a CNC beginner needs, built around short daily recall instead of long manuals.
G00 is a rapid positioning move and G01 is a controlled linear feed move. Here is the difference, why beginners mix them up, and how to keep them straight.
G02 cuts a clockwise arc and G03 cuts a counterclockwise arc. Here is how to tell them apart, which way to look, and why beginners reverse them.
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.
M03 starts the spindle clockwise, M04 starts it counterclockwise, and M05 stops it. Here is what each does and how to remember the set.
A short reference of the M-codes you will meet first: spindle, coolant, tool change, and program control, each with a plain-language meaning.
