🔧 CNC Programming with Hadrian Robotics

Lesson Objective: Master basic CNC G-code commands using interactive learning techniques, TPR methods, and memory aids

Duration: 90 minutes | Level: Beginner to Intermediate

🎯 Lesson Overview

This interactive lesson combines kinesthetic learning (TPR), visual aids, and memory techniques to teach CNC programming fundamentals using Hadian Robotic software.

Learning Outcomes

• Understand coordinate systems (X, Y, Z axes)
• Write basic G-code commands
• Apply the S.T.A.R.T. programming methodology
• Execute safe CNC operations

Materials Needed

• Hadian Robotic software (simulation mode)
• Printed reference cards
• Classroom space for movement activities
• Projector/screen for demonstrations

🌟 The S.T.A.R.T. Method

Our proven methodology for CNC programming success:

S

Set Zero

Establish work coordinate origin (G54)

T

Tool Selection

Choose tool & spindle speed (T01 M06)

A

Approach Point

Safe move to start position (G00)

R

Run Operation

Execute cutting path (G01, G02, G03)

T

Terminate Safely

Retract & stop (M05, M30)

💡 Memory Tip

"Every STAR-T leads to success!" - Use this phrase to remember the sequence.

🎴 Interactive G-Code Flashcards

Click each card to reveal the meaning. Master these fundamental commands:

G00

Rapid Movement

Moves tool quickly without cutting

Example: G00 X10 Y10

G01

Linear Interpolation

Straight line cutting movement

Example: G01 X20 Y20 F100

G02

Clockwise Arc

Circular cutting - clockwise direction

Example: G02 X10 Y0 I-5 J0

G03

Counter-Clockwise Arc

Circular cutting - counter-clockwise

Example: G03 X10 Y0 I5 J0

M03

Spindle On (Clockwise)

Starts spindle rotation

Example: S1000 M03

M05

Spindle Stop

Stops spindle rotation

Example: M05

📝 CNC Programming Sequence

Follow this logical flow for every CNC program:

1

Initialize Program

% (Program start) - G90 (Absolute positioning) - G54 (Work offset)

2

Tool Selection & Spindle Setup

T01 M06 (Tool change) - S1000 M03 (Spindle on at 1000 RPM)

3

Approach Workpiece

G00 X0 Y0 (Rapid to start) - G00 Z5.0 (Safe height)

4

Begin Machining Operations

G01 Z-2.0 F100 (Plunge cut) - Execute cutting moves

5

Safe Retraction

G00 Z5.0 (Retract) - M05 (Spindle stop)

6

Program End

G00 X0 Y0 (Return home) - M30 (Program end & rewind)

🎭 Human CNC Machine Role Play

Roles to assign:

• The Tool: Student who moves according to G-code commands
• X-Axis Controller: Directs left/right movement
• Y-Axis Controller: Directs forward/backward movement
• Z-Axis Controller: Directs up/down movement
• G-Code Reader: Calls out the commands
• Quality Inspector: Checks if movements are correct

🔧 Tool Change Pantomime

Act out these motions as you learn:

1. 🤏 Pick up tool from tool holder
2. 🔄 Insert into spindle
3. 🔧 Tighten tool holder
4. 📏 Touch off tool to set length
5. ▶️ Start spindle rotation
