Circle Diameter
Enter the diameter of the part.
Lead-In Radius
Overburn Length
Parts that contain a circular element user overburn. Overburn specifies the arc length that
the torch will travel past the circle closure point. The dimension entered is the chord
length of the overburn-arc.
In some cases it is desirable to have an underburn length. For these conditions, enter a
negative number for the overburn length.
Lead Out Radius
Part Type
Indicate whether you want to cut the part as a separate piece or a hole in a larger part.
Chain cut options are available for simple shapes that have external cut paths.
Lead Type
Depending on the shape you select, the style of the lead in/ lead out can be selected as
radius, lock or straight line. The lock style lead-in creates greater stability for the part
and is only available if the part type is set to piece. Lead-in selection is only available if
the part type is set to piece or hole.
Note: Some shapes offer drop down fields to increase options with additional parameters.
