CNC (Computer Numerical Control) has transformed manufacturing by automating what was once manual machining. In this guide, we’ll cover:
-
Key Terminology: G‑code vs. M‑code, axes (X/Y/Z), work offsets, coordinate systems (G54–G59).
-
Workflow Overview: Designing in CAD → generating toolpaths in CAM → post‑processing to G‑code → executing on the machine.
-
Machine Components: Controllers, drives, spindles, linear guides, ball screws, workholding.
-
First Cuts: Setting your zero, safe Z heights, running in “dry‑run” mode, and verifying toolpaths.
-
Common Beginner Mistakes: Skipping calibration, using wrong units (inch vs. mm), neglecting clearances.
Mastering these fundamentals ensures a smooth entry into CNC machining and lays the groundwork for every advanced topic ahead.
