Milling a hole
It is now time to implement a machining strategy for the big hole at the center of our part. It’s quite a big feature since it is a pilot hole for an M36x4 thread with a diameter of 32 mm. With such a diameter, it is impossible to use a drill bit; therefore, we have to create a milling operation instead.
In order to reduce tool changes, we are going to use the same tool already used for the previous operation. This type of tool is suitable for many different milling operations. There are multiple commands inside Fusion 360 to mill a hole; for example, we may go for another Adaptive Clearing operation.
However, I want to introduce you to as many commands as possible; therefore, we are going to use a command that we can find in the 2D Operations set called Bore. This command is specifically used for machining cylindrical or conical features and is perfect for our case:
