Stock definition and setup in CNC Programming - Mini Project: Build & Apply

Stock Definition and Setup

📖 Scenario: You are programming a CNC machine to cut a metal part. Before starting the cutting, you need to define the stock material size and position it correctly in the machine's coordinate system.

🎯 Goal: Create a CNC program that defines the stock size and sets up its position for machining.

📋 What You'll Learn

Define the stock size with exact dimensions

Set the stock origin position

Use standard CNC programming commands for stock setup

Output the stock setup commands

💡 Why This Matters

🌍 Real World

Defining stock size and position is essential before machining to ensure the CNC machine cuts the correct material area.

💼 Career

CNC programmers and machinists use stock setup commands daily to prepare machines for production runs.

1

Define the stock size

Write CNC code to define the stock size with length 100, width 50, and height 20 using the #100, #101, and #102 variables respectively.

CNC Programming

# Define stock size variables
# Your code here

Need a hint?

Use variables #100, #101, and #102 to store length, width, and height.

2

Set the stock origin position

Add CNC code to set the stock origin position at X=0, Y=0, Z=0 using variables #110, #111, and #112.

CNC Programming

# Define stock origin position variables
# Your code here

Need a hint?

Set origin coordinates using #110, #111, and #112.

3

Apply stock setup commands

Write CNC commands to apply the stock size and origin position using G54 coordinate system and variables #110, #111, and #112 for origin offsets.

CNC Programming

# Apply stock setup using G54 and origin offsets
# Your code here

Need a hint?

Use G54 with X#110, Y#111, and Z#112 to set the coordinate system.

4

Output the stock setup

Write a comment line that outputs the stock size and origin position in the format: (Stock: Length=100, Width=50, Height=20, Origin=(0,0,0)).
