CNC Metalworking

Advantages of CNC Milling

CNC milling has a number of advantages over other manufacturing processes.

Can produce quality parts of almost any shape or form

Cost-effective machining for prototyping and short runs

High dimensional tolerances are possible

Smooth finishes can be achieved

Can produce identical parts repeatedly

Milling machines can operate at high speeds, producing parts quickly.

A single machine can produce a wide variety of part shapes and sizes

Milling can be applied to many materials, including metals, plastics, and composites.

CNC machines can be programmed using computer-aided design (CAD) software, which makes it easy to create and change designs.

Design Consideration for Milling

When designing parts to be CNC milled, there are several tips to keep in mind:

CNC milling machines are capable of precision so try to use this to your advantage

Avoid deep pockets which are difficult to machine

Sharp inside corners are often difficult so consider using a radius

Apply chamfers to top edges to reduce sharpness and improve appearance.

Apply filters to the bottom of pockets to reduce the possibility of stress fractures if the component will be under stress.

Thin walls and other flimsy shapes can be difficult to machine as they may not hold up against the pressure of the cutting action.

Try to create shapes that do not have complex curves in more than one axis – as it may be difficult to hold during machining.
