This is a video solution for practice Exercise 3. For this next practice exercise, we're going to use the file C2-W2-PE3. We want to navigate to the manufacturer workspace, and we want to create a new setup. We need to make sure that the coordinate system is pointing up. So we need to select a reference for Z, and we can place the coordinate system in the center of the part. For the stock, we're going to set the stock offset to zero on both the side and the top, and we're going to say "OK". From here, we need to create a 3D adaptive clearing tool path. We're going to start this by using our Samples library, filtering by flat end mill, and selecting a half inch flat end mill. We're going to take a look at the passes and the stock to leave, and we're going to turn off Axial stock to leave. But we'll leave the radial stock at 0.02 and say "OK". Once complete, let's go ahead and simulate it to see what materials left behind. So you can see here exactly what's left for us to machine. So we need to do some additional tool path creation. We can make some modifications to the original tool path. In the passes section, we can change the maximum roughing step-down value to 0.4, and we can change the fine step-down value to 0.01. This will get us a little bit closer to that final shape. We can also make sure that machine cavities is turned on, and we can also use flat area detection. This will allow us to make sure that we've machine the flat areas in the design. Once this one is done calculating, we can simulate it and see what material changed. Again, I'm going to jump to the end of the tool path. We can see here that we're a little bit closer to the final shape, but there are areas where the tool just isn't able to get to. So now, let's go in and create an adaptive rest tool path. We're going to change the tool that we're going to use. Navigating to our samples library, we're going to filter by flat. We're going to go into a quarter inch flat end mill. Under Geometry, we want to use rest machining from previous operation. We're going to again leave stock, but we want to make sure that our axial stock to leave a zero. We're going to modify our maximum roughing and finishing step down values. Again, we'll use 0.4 and we'll use 0.01 for the fine. Also, want to make sure that machine cavities and flat area detection is on and say "OK". Because we are using rest and machining, this little avoid cutting in areas where machining has already happened. The half inch mill cleans out the majority of the areas, but the quarter inch goes back and fills in the gaps where the half inch wasn't able to get to. Once complete, let's select Setup 1 and simulate. Again, I'm going to jump to the end and allow it to just breeze through creating the stock, that way we can see what material is left behind. So you can see there is a little bit of material left behind and some finishing then asked to happen. But we're going to create one more tool path in this practice, and we're going to go to a 2D contour. We're going to continue to use the quarter inch flat end mill. We want to select the inside edge of our part. In the past is section make sure that we're not leaving any stock and say "OK". This will allow us to create a finishing tool path around the inside area of that edge, and this way we could go back with a ball and mill, and finish off the smooth geometry. This wraps up this practice exercise, so go ahead and save your file.
