Content

1. Operation of Woodworking Machines

Woodworking machines are mechanical devices used to shape, cut, or finish wood. These machines help increase productivity, accuracy, and efficiency in woodwork.

Common Woodworking Machines Include:

• Table Saw: Used for making straight cuts in wood.
• Lathe: Used to shape wood by rotating it against cutting tools.
• Sander: Used to smooth wood surfaces.
• Drill Press: Used for drilling holes in wood.

Operation Skills:

• Understanding the machine’s parts (e.g., motor, blades, switches).
• Properly setting up and adjusting the machine for the task.
• Using the machine with a focus on precision and control.

2. Safety Measures in the Workshop

Safety is critical when working with woodworking machines due to their power and moving parts.

General Safety Guidelines for Woodworking Machines:

• Wear Appropriate PPE: Always wear goggles, gloves, ear protection, and a dust mask.
• Check the Machine Before Use: Ensure that all parts are in good working condition, including blades, belts, and switches.
• Follow the Manual: Always read and follow the manufacturer’s instructions.
• Keep Hands and Clothing Clear: Avoid placing your hands near moving parts. Use push sticks or other tools to guide the wood.
• Turn Off the Machine After Use: Always turn off the machine and unplug it when not in use.

Safety Demonstrations:
The teacher demonstrates how to safely operate a table saw, lathe, or any other relevant machine. Students observe the safety precautions in action.
