Defining parting toolpaths

00:08

Parting, or cutting off, a model from the stock is an essential step in the turning process.

For this video, open the file Parting Toolpath.f3d.

00:22

In the Manufacture workspace, from the Browser, expand Setup1.

00:29

There are already several toolpaths applied to this part. Select each toolpath to review it. With facing, roughing, grooving, and drilling toolpaths applied, you can begin to plan to part, or cut off, the model from the stock. Parting, or cutting off, a model from the stock is an essential step in the turning process. With the exercise file open, in the Manufacture workspace, from the Browser, expand Setup1. There are already several toolpaths applied to this part. Select each toolpath to review it. With facing, roughing, grooving, and drilling toolpaths applied, you can begin to plan to part, or cut off, the model from the stock. From the Toolbar, in the Turning tab, expand Turning, and then select Turning Part. The Part dialog displays. In the Tool tab, under Tool, notice that by default, the program inherits a previously used tool appropriate for the parting operation. However, a different tool will be used in this case. Next to Tool, click the selection tool. The Tool Library displays. From the library list, under Fusion 360 Library, select Turning - Sample Tools. Then, from the list of sample tools, select OD Grooving with a corner radius of 0mm. Click Select. Notice in the canvas, the tool displays. The end of this tool is rounded, whereas the previous tool had a square end. Back in the Part dialog, you can configure other settings in the Geometry, Passes, and Linking tabs, but for now, leave the settings as they are. Click OK. Simulate the toolpath to see how the part would be parted using these settings. From the Browser, select Setup1 to display the setup. Then, from the Toolbar, in the Actions panel, select Simulate. The Simulate dialog displays as well as the Simulate player. Back in the Browser, select the Part toolpath, and then, from the Simulate player, click Play. Notice that the toolpath has a few issues. First, the tool is not long enough to successfully part the model from the stock. Second, the toolpath collides with the model. In the Simulate dialog, click Close. Back in the Browser, right-click the Part toolpath, and from the shortcut menu, select Edit. The Part dialog displays again. Open the Geometry tab. From here, enable Edge Break. When enabled, this allows you to chamfer or radius the back edge of the part before the cut off is complete. Ensure Edge Break Type is set to Chamfer. In the Chamfer Width field, enter, “.015”. Next, open the Radii tab. From here, you can set a radial containment area for machining. Under Outer Radius, you can configure the largest radial boundary of the cutting area. Expand the From drop-down and select Model OD. This sets the clearance radius according to the outside diameter of the defined model, so the Chamfer Edge Break will be the correct size. Under Inner Radius, you can configure the smallest radial boundary of the cutting area, controlling the maximum depth for the cut area. Expand the From drop-down and click Selection. Now, you can select any face, vertex, or point on the model to define the radius. In the canvas, orbit and zoom into your model and select the interior cylindrical face of the model. Next, define an offset. In the Offset field, enter, “-.05”. Now, open the Passes tab. Under Passes, enable Allow Rapid Retract. This lets the tool retract as quickly as possible. Click OK. Simulate the toolpath again. From the Browser, select Setup1, and then, from the Toolbar, in the Actions panel, select Simulate. Back in the Browser, select the Part toolpath. In the Simulate Player, click Play. Zoom into the model and toolpath to review the way the tool moves. Notice that the tool clears the model now with no collisions, it adds a chamfer edge, and it cuts the part off completely. There are several options when working with parting toolpaths to ensure a collision-free cut off.
