Lead In and Lead Out

Lead-in and lead-out are crucial for smooth entry and exit of the tool during CNC Routing operations. They help to avoid abrupt changes in tool movement, minimize surface marks, and reduce tool wear. Here’s how you can use lead-in and lead-out on a CNC:

General Steps:

1. Set Tool Compensation(If using): Use G41 or G42 depending on which side of the path you want the tool to be offset.

2. Program Lead-In: Before the tool reaches the cutting path, use either G01 (linear) or G02/G03 (circular) commands to move the tool into position.

3. Perform the Cut: Once the tool is aligned with the desired path, execute the machining operation.

4. Program Lead-Out: After completing the contour or cutting operation, move the tool away smoothly using a lead-out with G01 or G02/G03 commands.
