Turning Tutorial

This tutorial will guide you through creating your first CNC turning program.

Preparation

Before starting:

• Select a lathe from the inventory browser
• Set up a cylindrical workpiece
• Configure the turning tools

Lathe Coordinate System

In CNC lathe:

• X = diameter (or radius, depending on configuration)
• Z = longitudinal axis (workpiece length)

Example: Facing and Roughing

Turning Cycles

G70-G76 cycles simplify common operations:

• G70: Finishing cycle
• G71: Longitudinal roughing cycle
• G72: Face roughing cycle
• G73: Pattern repeat cycle
• G76: Threading cycle
