1.1 Basics of CNC Machining

To comprehend how CNC machining removes material from the work block, there are three basics conventional machining technologies.

• Drilling work: Drills work function is by rotating the drill bit and moving the bit to meet or drilling a hole with stationary work block.
• Lathe work: Lathe is to spin the work block of material against the stationary drill bit or cutter tool to remove material in a circular or fluid path.
• Milling work: Milling machine is the process of machining using rotary cutters to remove material by advancing a cutter into a work block. It can be done by varying direction on one or several axes, cutter head speed, and pressure.
