What is Milling ?

Milling operations involve using multi-point rotary cutters to remove material from a workpiece.

There are two main types of milling operations: face milling and peripheral milling. Face milling cuts flat surfaces into the workpiece and flat-bottomed cavities. The feed can be either horizontal or vertical. Peripheral milling cuts deep slots, threads, and gear teeth.

The workpiece can be fed into the cutting tool in either of two ways. Conventional milling involves feeding the workpiece against the cutter rotation. This is the recommended method for manual milling machines. Climb milling, on the other hand, feeds the workpiece in the same direction as the cutter rotation. This is the preferred method for CNC milling.

Milling is best applied as a secondary process to an already machined workpiece. It helps to define features and serves as a “finishing coat”. Use milling as a secondary process to add features such as holes, slots, pockets, and contours.


Drilling machining process

What is Drilling ?

Drilling creates a round hole in a workpiece. A drill press or tapping machine is designed for drilling, but this process can also be performed using a milling machine.

Chips are the bits of waste metal produced when machining a workpiece. The shape of the drill bit helps chips fall away from the workpiece, keeping the workpiece free of debris.

Placing the drill bit perpendicular to the workpiece reduces drifting or leading-off. For even more precision, a center drill operation is often added before drilling. Some drilling operations need angular drilling. Angular drilling requires special work-holding tooling. Other options include: rotation of the head on a manual machine or use of multiple axis’ on a CNC machine.

    Ways to prevent drifting include:

  • Casting/molding/forging a mark

  • Center punching

  • Spot drilling/center drilling

  • Spot facing

Like with turning operations, different drill bits exist for specific drilling operations. Below are a few special drill bits along with their specific uses.
Spotting Drills – short drills used to create shallow or pilot holes. If using a longer drill for these shallow holes it could have a tendency to drift.
Peck Drilling – frequent retracting of the drill helps to clear chips from the workpiece and prevent drifting.
Screw Machine Drills – these drills are short and can create straight and accurate holes without the need for prior spotting.
Chucking Reamers – used to enlarge previously drilled holes to very precise diameters.
