Day 1: Lathe Anatomy & Tooling
Before spinning anything at high RPMs, you must understand the mechanics of the "Turning Center."
Machine Configuration: Understanding the $X$-axis (diameter) and $Z$-axis (length).
The Spindle & Chuck: Proper installation of hard jaws vs. soft jaws and the critical importance of clamping pressure.
Insert Geometry: Learning the "alphabet soup" of carbide inserts (e.g., CNMG, VNMG). Understanding rake angles and nose radii.
The Turret: How to load tools and ensure they are "on center." If a turning tool is even 1mm above or below the center line, the part geometry will fail.
Day 2: Offsets and Manual Data Input (MDI)
Day two focuses on the communication between the operator and the controller (typically Fanuc, Haas, or Siemens).
Work Offsets (G54): Setting the "Z-zero" at the face of the part.
Tool Geometry Offsets: Using a tool probe or the "paper method" to tell the machine the exact position of the cutting tip.
Conversational Programming: Using the machine's built-in software to create simple shapes like shoulders, tapers, and radii without external CAD/CAM.
Essential G-Codes for Lathes:
Day 3: CAM, Threading, and Parting
The final day covers the most "dangerous" but rewarding operations: cutting threads and separating the part from the bar stock.
CAM for Turning: Using software to define "Turning," "Facing," and "Grooving" operations.
Boring Operations: Learning how to machine the inside diameter (ID) of a part safely.
Threading: Synchronizing the spindle rotation with the $Z$-axis feed to create precise screw threads.
Parting/Cut-off: The final step of dropping the finished part into a "parts catcher."
Final Project: Machining a multi-feature "Bolt and Nut" or a "Chess Piece" to verify all learned skills.
