Everything before this topic is preparation. CNC Machining is where the rubber meets the road. All the steps of CNC before machining are just preparing for the machining phase of the project. A simple definition of machining is removing material. You remove material in various ways to come up with the part or piece.
CNC Machining can be performed on numerous types of material. For example, wood, steel, aluminum, and stone. Machining generally has higher tolerances associated with it. When machining, you are trying to do something more precise.
In machining, we use some sort of tool. This tool could be a grinder, drill bit, end mill, router bit or other tool. There are infinite variations of tools. CNC Tooling generally costs a fair amount of money. Once you invest in your tooling though, you can use it again and again until it wears out. If you have a large variety of different tools, you will be able to perform a large variety of machining types.
Here is a list of common tooling used in CNC Machines:
Drill bits
End mills
Plasma cutter
Dovetail cutter
Fly cutter
