• Lead-in = Entry path before cutting.  
• Lead Length = Distance of the entry path.
• Angle = Direction of entry.
• Circular Lead = Curved entry instead of straight.
• Lead Out = Exit path after cutting.
• Overcut = Extra cutting beyond the contour endpoint.
  

Lead Types

A.  Straight Line Lead

When Straight Line Lead is selected, the tool approaches the contour in a straight line before starting the cut.

In the example shown:

• Angle: 90°
• Lead Length: 10 mm

The cutter starts 10 mm away from the contour and approaches it at a 90° angle.

B.  Circular Lead

When Circular Lead is selected, the tool enters the contour using an arc rather than a straight line.  This ensures a smoother tool entry and less stress on the material. 

The Radius setting controls the size of the arc.
