In this video, we're going to define a new tool. After completing this step, you'll be able to create a custom endmill and create a cloud, a tool library. In Fusion 360, we want to get started with the dataset manufacturer toolpaths. We are automatically in the manufacturer workspace, but if you're designing opens up in the design workspace, make sure that you do navigate to manufacture. This design contains a setup which is going to be the basis for the definition of our coordinate system, our stock and exactly what we're going to machine. Before we move on, I want to make sure that we go up to our user preferences. In the general section, we want to go to manufacturer and make sure that we enable Cloud libraries. Once that's enabled, let's make sure that we go to our manage tool library section, and in the Cloud section, we're going to create a new library. We can do this by pressing the plus icon or by right-clicking and selecting "New Library". While you can't save these locally, it is helpful to save them in the Cloud because anytime you log into Fusion 360 from a different computer, you'll still have access to any of your Cloud data. From here, we're going to create one that is intro to DFM or design for manufacture. Currently, there's no data in here, and we can copy tools from the Fusion 360 library, or we can create our own from scratch. We're going to start by learning how to create our own by hitting the plus icon. Then we need to determine what type of tool we're creating. For our video, we're going to create a new flat endmill. We're not going to fill out any of the general perimeters, but the description, vendor, product ID, and link are going to be helpful if you're replicating a real tool. Since we're doing this as an exercise, we're not actually replicating a real tool. We're just exploring the options. In the cutter section, we want to define things like the direction of rotation, the number of flutes, the material of the tool, and its values. The diameter of the tool is going to be half-inch. The shaft diameter is automatically linked to the tool diameter, so we don't need to update it unless it's different. The overall length of our tool is going to be two and a half inches. The length below holder is going to be one and a half inches. Notice anytime we select a perimeter, it's highlighted on the right-hand side, showing you what we're setting. The shoulder-length of our tool is going to be one inch and the flute length is going to be 0.75. Now that we've defined the tool, we can move on to the next section, which is shaft. In this case, we don't need to modify any of these parameters, but we do want to create or select a holder. We are dealing with a half-inch tool, and we can select some of the standards like CT40-Blink 1 by double-clicking on blink 1 or blink 2. Or we can go down into the samples library and find one of the holders that will work for us. Notice that some of these go up to a quarter-inch diameter, but not any larger. If we were to use a quarter-inch diameter holder, this is obviously not right for our tool. For our purposes, we're going to go ahead and select a CT40-Blink 2, and we're going to use this as our holder for this example. In the cutting data section, we determine how fast the spindle is spinning, how fast the tool is moving. Also, whether or not we want to override some of the values that are used in toolpaths. For example, if we want a very specific step-over value or a step-down value, we can use these parameters which will override the ones in the default toolpath. One thing that we do need to be aware of in the post-processor section is the tool number. For example, if this was tool number 6 inside your tool crib, you would want to make sure that you set this number to six. From here I'm going to accept, and now we've created our new tool in the tool library. I can go ahead and close this. Because it's automatically saved to the Cloud, we don't need to make any further saves. If you've made any changes to the design, make sure that you do save before moving on.
