Why Proper Tool Setup Prevents Crashes

📖 Scenario: You work in a CNC machining workshop. Setting up the right tools correctly is very important to avoid machine crashes that can damage the machine and waste materials.Imagine you have a list of tools with their sizes and types. You want to check if the tools are set up properly before starting the machine.

🎯 Goal: Build a simple script that stores tool data, sets a safety size limit, filters out tools that are too big, and then prints the safe tools to use. This helps prevent crashes by ensuring only properly sized tools are used.

📋 What You'll Learn

Create a dictionary called tools with tool names as keys and their sizes (in mm) as values.

Create a variable called safety_limit with the maximum allowed tool size (in mm).

Use a dictionary comprehension to create a new dictionary safe_tools with only tools smaller than or equal to safety_limit.

Print the safe_tools dictionary.

💡 Why This Matters

🌍 Real World

In CNC machining, using tools that are too large or not set up properly can cause crashes that damage machines and waste materials. This script helps check tool sizes before running the machine.

💼 Career

CNC operators and programmers must verify tool setups to ensure safe and efficient machining. Automating checks reduces errors and downtime.

1

Create the tools dictionary

Create a dictionary called tools with these exact entries: 'EndMill': 12, 'DrillBit': 8, 'LatheTool': 15, 'Tap': 6.

CNC Programming

# Create the tools dictionary with exact entries
# Your code here

Hint

Use curly braces {} to create a dictionary with the exact tool names and sizes.

2

Set the safety size limit

Create a variable called safety_limit and set it to 10 to represent the maximum allowed tool size in millimeters.

CNC Programming

tools = {'EndMill': 12, 'DrillBit': 8, 'LatheTool': 15, 'Tap': 6}
# Set the safety_limit variable to 10
# Your code here

Hint

Just assign the number 10 to the variable safety_limit.

3

Filter tools by safety limit

Use a dictionary comprehension to create a new dictionary called safe_tools that includes only the tools from tools with sizes less than or equal to safety_limit.

CNC Programming

tools = {'EndMill': 12, 'DrillBit': 8, 'LatheTool': 15, 'Tap': 6}
safety_limit = 10
# Create safe_tools dictionary with tools <= safety_limit
# Your code here

Hint

Use {name: size for name, size in tools.items() if size <= safety_limit} to filter the dictionary.

4

Print the safe tools

Print the safe_tools dictionary to show which tools are safe to use.

CNC Programming

tools = {'EndMill': 12, 'DrillBit': 8, 'LatheTool': 15, 'Tap': 6}
safety_limit = 10
safe_tools = {name: size for name, size in tools.items() if size <= safety_limit}
# Print the safe_tools dictionary
# Your code here

Hint

Use print(safe_tools) to display the filtered tools.
