Face milling

As described in Chapter 8 (as shown in Figure 8.2), the first milling operation we have to implement is facing the top side of the stock; here, we have to remove a layer of 1.5 millimeters of our part.

At the moment, the stock is 45 mm tall, and we need to bring it down to 42 mm by removing 1.5 mm from both the top and bottom face, to have a good surface quality. As discussed in Chapter 6, the best strategy to remove a flat layer of material is face milling, a fundamental milling operation that allows us to machine flat areas.

Note

Depending on the quality of the stock, we may need to increase the amount of extra material to remove for a successful facing operation. The more the stock is bent or irregular, the more material we shall remove, and the bigger the stock shall be.

Let’s begin with finding the right tool and parameters using our trusty Sandvik CoroPlus.
