In this lesson, we'll be identifying open and closed pocket geometry. After completing this lesson, you'll be able to analyze part geometry and identify open and closed pockets. For this next lesson, we're going to be taking a look at three different files. Our 3D pocket sample, our 2D pocket sample and uploading a supplied file open pocket clearing. The first thing that we're going to do is we're going to take a look at our 3D pocket sample and try to identify both open and closed pockets. The pocket that we machined already is closed, meaning that it is a complete surrounded border and there's no exit or entry of the pocket from the outside. If we rotate this part around, you can see that we have a dome on the bottom and we have this channel that runs through it. This is an open pocket allowing us to get into and out of the pocket from the outside. If we explore our 2D pockets sample, the top phase that we already programmed is a closed pocket. The geometry on the outsides, are open pockets. These are ones that have an opening to the outside of our part and allow the tool to enter and exit geometry. If we rotate this around, the bottom is closed. Now we have two separate levels in here but this is essentially one closed pocket. Then if we take a look at the file that we're going to be working with here, open pocket clearing, this has a few smaller pockets on it. It has these small open pads that are open pockets and it has these slot geometry here that are closed pockets. However, the overall part is something that we can use and utilize our pocket clearing operations. So when we look at geometry and we see this part, we don't necessarily instantly think pocket clearing. But we're going to explore this part and we're going to figure out how we can use it and use some of those pocket clearing tool paths. The first step however is to get into the manufacturer workspace and setup a new cam setup. This file doesn't have anything set up yet. We are going to still use the same tool library from all our previous examples, but we want to go into setup and create a new setup. We're going to be using milling, and for our model orientation we're going to reset the Z and X axis. The Z is going to be pointing up and the X to the right, and we're going to use the box point in the upper left-hand corner. For our stock, we're going to do a relative size box, but we're not going to add any stock to the sides. We're going to set these all to zero, which means that the complete outside is going to be the correct shape, assuming that we're starting with a perfectly machine rectangle. Then for the top offset we're going to add a small amount, and I'm going to say one millimeter noting that this file has come in is metric. Sometimes it's a good idea to check this first but as soon as you get into changing any parameters in a tool path or setting up stock, you'll instantly know what units you're using, because those units will propagate throughout anything we're doing inside of here. So let's go back and let's edit that setup. Go back into stock and let's change the stock on top of our part to 0625. Now that we have this setup complete, we're ready to start machining, but let's go ahead and save the file before moving on to our next step.
