This is a video solution for Practice Exercise 3. For this next exercise, we want to use this applied file C2-W3-PE3. We're going to navigate to the manufacturer workspace, and we want to create a new set-up. We want to make sure that the model orientation has z pointing up, and if we need to select the y-axis, we can hold down the left mouse button and it'll allow us to select it through the solid geometry. From here, I also want to change the stock to be a relative size cylinder. Make sure that the coordinate system is still fine and then say okay. We're going to be creating a three-axis scallop tool path. So we want to navigate down to scallop, and we want to select a tool to use. We're going to go to our samples library and filter by a ball end mill, and we're going to select a quarter-inch ball end mill. From here in the geometry section, the machining boundary is automatically set to the silhouette of the part without any adjustments on our part. For our parses section, we can go ahead and we leave all these standard and say okay and see what the result looks like. Also note, we didn't make any adjustments to our coordinate system, so we should make sure that our coordinate system matches the coordinate systems set in our machine. Let's do a quick simulation to see what this looks like. So that's the part works its way around. You can see that it is starting to collide with the geometry on the outside, and there are certain instances where the tool actually does collide with the part. So in order to machine this part, we need a tool that extends farther out of the holder. We can modify the tool by right-clicking and selecting edit, and we can also edit the tool directly by right-clicking on it in the browser. If we select a tool here, we can modify it inside of our document by editing the tool, and in the cutter section, we want to make sure that the tool extends outside of the holder a bit farther. I'm going to set this to 1.5 and say okay, and allow it to update the tool path. Now, that should allow us to get around the part without colliding with the top of it. However, it doesn't take into account any of the other geometry. What we do need to take care of is the amount of step-down that we have in the scallop operation. So inside here, the current step over is set to 0.125, which is rather large. If we set this to something smaller such as 0.05, we'll get a much finer resolution on this part. Now, let's go ahead and simulate. So as we play through, the tool should now be a little bit closer to the final shape of our part. Now, obviously with a part like this, we would want to do some 3D adaptive clearing first before we started to do our finishing operation, but really we're just looking at the scallop tool path. If we want to, we can always go back and do a 3D adaptive clearing using a larger end mill such as a half inch flat. Filter by type and select a half-inch flat end mill. In the geometry section, make sure that we turn off the option for rest machining, and we'll just leave all these default settings, and we'll leave stock to leave as well. Once this is done calculating, we can make sure that we drag this up above our scallop, and then we can make sure that we select both and simulate it. Now, if we jump past the first operation, the geometry is a little bit closer. You can see a small amount of colliding, and this means that the tool is likely not extending far enough out of that holder as well. So these are things that would need to be adjusted, but this way, we can take a look at the scallop operation and make sure that it's removing all the geometry that we would expect. Now, this is ready to go back with a smaller tool and finish off some of the other areas. Make sure after we've simulated that you save your file.
