Summary: Guiding cutting tools for repetitive operations.

Jigs are specialized tools used in manufacturing to guide cutting tools or position workpieces accurately for repetitive operations. Unlike fixtures, which only hold the workpiece, jigs also guide the tool itself, ensuring that each part is machined or assembled in exactly the same way.

Function: Jigs are designed to:

    * Control the tool's path, such as guiding a drill bit to create holes at precise locations.

    * Ensure that parts are assembled in a consistent orientation.

    * Increase production speed by simplifying and speeding up repetitive tasks.

Design: Jigs are custom-made for a specific part or operation and often incorporate features like:

    * Bushings to guide drill bits.

    * Locating pins to position the workpiece.

    * Clamps to hold the workpiece securely.

Applications: Jigs are commonly used in:

    * Drilling

    * Reaming

    * Tapping

    * Assembly

Importance: Jigs are crucial for:

    * Achieving high accuracy and repeatability in manufacturing.

    * Reducing the skill level required for certain operations.

    * Increasing production efficiency.

   In essence, jigs are essential tools for mass production, enabling the creation of identical parts with precision and speed.
