There are typically multiple options to choose from in operations to create a specific part or component. One of the newer technologies available to create both simple as well as much more complicated types of items is 3D milling.
It is important to realize that 3D milling is not the same as 3D printing, although both can be used in the development of both prototypes as well as in production. The use of CNC (computer numeric control) milling machines allows a solid block of the material, typically a metal or a plastic, to be shaped into the desired final part.
In this way 3D CNC milling shapes and forms the part by removing specific areas from the solid block to create the shape. 3D printing, on the other hand, generates the shape rather than using a subtractive method to remove material.
Ease of Product Design
CAM (computer aided manufacturing) or CAD (computer aided drafting) software is used to create and develop the virtual part or component. The software can also be used to run virtual analysis and tests on the part, which results in faster prototyping through a more effective original design.
This CAD/CAM drawing is then uploaded into the 3D milling machine. The engineers configure the system, and then the program operates the milling machine, creating an exact copy of the drawing.
Speed of Production
A considerable advantage of the choice of milling using 3D technology is the speed of production of parts. With extremely fast cutting ability, even with challenging metals and materials, the cost of part production can be kept low, particularly on high volume orders.
In addition to the speed of production, the precision in the parts as well as the detail possible through the single operation makes secondary operations such as deburring or grinding unnecessary. This further assists in decreasing the time and cost of this important milling operation.
