Rotary - Collision avoidance

00:03

The Collision Avoidance feature included in the Fusion Manufacturing Extension

00:08

detects any potential collisions between a tool shaft, tool holder, and component.

00:13

Collision Avoidance then automatically selects the most suitable direction in which to tilt the tool to avoid collisions,

00:20

enabling you to reach more areas of a part in a single operation.

00:25

Take a moment to review these examples of rotary parallel toolpaths

00:29

to better understand how Collision Avoidance improves the manufacturing process.

00:34

Each toolpath shown here is calculated with a 0.8 mm Stepover,

00:39

and the Style is set to Spiral.

00:42

In the first scenario, in the Strategy dialog, Multi-Axis tab, Collision Avoidance is not selected for the toolpath.

00:50

When the toolpath is simulated, it is easy to spot multiple collisions between the path and tool.

00:59

In the second example, Collision Avoidance is selected, and the Mode is set to Trim.

01:06

When simulated, you can now see that, while there are no collisions, the toolpath does not machine the entire component.

01:14

This is because the colliding segments have simply been removed.

01:18

Finally, in the last example, Collision Avoidance is selected,

01:22

and the default value for the Smoothing Distance is left in place—this value is calculated using the tool diameter as a reference.

01:30

Now, when the toolpath is simulated, there are no collisions, and the strategy correctly machines the entirety of the component.

01:38

The tool tilts in the correct direction, maintaining the full axis constraint, avoiding potential issues,

01:44

and preventing any jerky motions of the rotary axis.

01:48

The Collision Avoidance feature is a valuable tool to help create an efficient process

01:53

when machining complex parts with more than 3 axes.
