The side feature can utilize one or more closed or open curves. The Punch or Die feature provides more cutting options for closed curves. You can optionally place the wire on either side of the curves. A side feature must have at least three arcs or lines in it including the lead moves.
The thickness parameter is used to access the appropriate cutting data table.
The A parameter is used to rotate the feature around the Z-axis of the current setup.
A 2-axis side feature can create a number of cutting operations. These are specified on the Strategy tab.
