In this second lesson, we will program another 5-axis simultaneous milling part, further exploring FeatureCAM's 5-axis machining capabilities. Like any other part in FeatureCAM, we will utilize the same workflow to help guide us through the programming of this part.
With a blank milling document open, we can now import our solid model to program features from.
The Import Wizard will help us setup our part, covering our stock step, as well as some of our machining prep.
Now that we have gone through the familiar process off importing and setting up our solid model, let's import a model to be used to define our stock material, as if we are machining a part that has already been through an operation on a lathe.
With our stock solid model imported, we simply need to apply this model to the Stock section of FeaturCAM
Now that we have completely worked through the import wizard, and defined our stock, we have just a few short steps left before we start programming features.
With our part imported, stock setup, and machining details accounted for, we are ready to start programming!
It looks like we have a few issues to correct with our toolpath. First, we obviously have a gouge, and will need to add some multi-axis control to avoid any collisions. It also seems that our cutter is cutting past the edges we specified.
In the past, we have looked at controlling our axes using the 'Fixed', 'Lead and Lean', and 'Automatic Tilting' options. For this lesson, we are going to take a look at the remaining options found under the 'Other' header in the 5-Axis tab. Specifically, 'From Point', and 'To Point'.
From Point - This option aligns the tip of the tool away from a fixed point, The angle of the tool is constantly changing. The tip of the tool moves significantly while the head of the machine tool stays relatively still.
To Point - This option aligns the tip of the tool towards a point. The angle of the tool is constantly changing. The head of the machine tool moves significantly while the tip of the tool stays relatively still.
Now that we have fixed any glaring errors with the toolpath, and explore the 'From Point' option, let's take a look at the inverse of 'From Point' - 'To Point'.
We can see that we are able to achieve a very similar result using the 'From' method instead in this case. The remaining 'To and From' methods all operate the same, only they reference lines or curves instead of points.
With our final simulation run, our NC Code has been generated and is ready to be sent to the machine.
