Tutorial: Leverage your 4th Axis by wrapping 2D toolpaths in Fusion 360 | Autodesk Fusion 360

In this Autodesk Fusion 360 video, Dylan Smith will demonstrate how to use your 4-axis by wrapping 2D toolpaths in the Fusion 360 Manufacturing workspace. Dylan will cover how to wrap toolpaths and how it can help you yield more from your 4th axis.

Before creating toolpaths, Dylan needs to ensure the setup is correct; more specifically, that the work coordinate system (WCS) is oriented correctly. The X-axis needs to be aligned with a rotary axis. The Fusion 360 wrap feature can be used with 2D Adaptive, 2D Pocket & 2D Contour. The 4-axis wrap feature allows the toolpath to be wrapped around perfectly cylindrical objects for geometry that is better machined using 4-axis instead of 3-axis. In the video, Dylan works with a component that has features which wrap around the component. A 3-axis style of machining is suboptimal for this type of component.

Select the geometry for machining and select the Wrap option in the Geometry tab. The next selection is for the geometry that will be wrapped around, in the Wrap Cylinder selection. Remember: This selection must be perfectly cylindrical, or it won’t be available to select. The Heights tab will differ slightly from other milling strategies, but the basic concept is the same. Due to the 4-axis nature of the toolpath, the heights are formed as circles instead of planes.

Autodesk Fusion 360 core users now have the ability to make the most of their 4th-axis using the wrap feature. This Fusion 360 feature can be used with 2D Contour, 2D Adaptive and 2D Pocket. We often come up against geometry that doesn't suit a 3-axis style of machining, so having this feature broadens the horizons in terms of parts we can manufacture.
