Generate a Parallel toolpath
On the Manufacture workspace toolbar, click Milling > 3D > Parallel.
The Parallel dialog opens.
On the Tool tab, click Select to pick a tool. If you have not created a tool to use, In the left panel of the dialog, from the Fusion Library, pick a tool from the Sample Tools library.
Tip: Bull-nosed and ball type end mills are best suited for the Parallel finishing toolpaths.
On the Geometry tab, you may contain the toolpath area with a Machining Boundary and then select the face, edge, or sketch that represents the area to be machined. If no selection is made, the entire model will be evaluated for machining within the defined Stock box.
On the Passes tab, set the Stepover to the cut spacing. A smaller distance will create a smoother surface finish.
Set the Pass direction to control the angle of the cut. Zero degrees starts at the 3 o'clock position, or the X+ direction.
Optional steps:
To control the Stepover value automatically based on the desired surface finish, enter a Cusp Height value.
To create a 90° "Cross Cut", enable Add Perpendicular Passes.
To create only climb cuts or only conventional cuts, set the Direction parameter.
To machine multiple Z depths, enable the Multiple Depths parameter.
To reduce the NC program size, enable Smoothing.
Click OK.
The toolpath is generated.
