Tool change command (M06) in CNC Programming - Mini Project: Build & Apply

Tool Change Command (M06) in CNC Programming

📖 Scenario: You are programming a CNC machine to drill holes with different drill bits. Each drill bit is called a tool and has a number. To switch from one tool to another, you use the M06 command followed by the tool number.For example, T2 M06 means change to tool number 2.

🎯 Goal: Create a simple CNC program that changes tools using the M06 command. You will first list the tools, then set a tool number to use, write the tool change command, and finally print the full command.

📋 What You'll Learn

Create a list called tools with tool numbers 1, 2, and 3

Create a variable called current_tool and set it to 2

Write a command string called tool_change_command that uses current_tool with M06

Print the tool_change_command string

💡 Why This Matters

🌍 Real World

CNC machines use tool change commands to switch drill bits or cutters automatically during manufacturing.

💼 Career

Understanding how to write and automate CNC tool change commands helps CNC programmers and machine operators improve production efficiency.

1

Create the list of tools

Create a list called tools with the exact values 1, 2, and 3.

CNC Programming

# Create the list of tools
# Your code here

Hint

Use square brackets [] to create a list with the numbers 1, 2, and 3.

2

Set the current tool number

Create a variable called current_tool and set it to the number 2.

CNC Programming

tools = [1, 2, 3]
# Set the current tool number
# Your code here

Hint

Use the equals sign = to assign the value 2 to current_tool.

3

Create the tool change command string

Create a string variable called tool_change_command that uses an f-string to combine current_tool with the text M06 in the format: T{current_tool} M06.

CNC Programming

tools = [1, 2, 3]
current_tool = 2
# Create the tool change command string
# Your code here

Hint

Use an f-string with f"T{current_tool} M06" to build the command.

4

Print the tool change command

Write a print statement to display the value of tool_change_command.

CNC Programming

tools = [1, 2, 3]
current_tool = 2
tool_change_command = f"T{current_tool} M06"
# Print the tool change command
# Your code here

Hint

Use print(tool_change_command) to show the command on the screen.
