CNC Machining is an automated process by which a machine processes a computer
file to create highly complex object from plastic or metal. We are CNC Machining
A tool, much like a drill bit, is used to cut away a metal or plastic block
in the shape of a 3D object or a mold to be later used in the plastic injection
process. Cutting away at an object is a process called subtractive manufacturing
because you start with a solid piece of metal or plastic and subtract from it to
create the specified part or object.
The tool is controlled along multiple linear or rotational axes. The more
axes a machine can control, the more complex part can be made. A 3 axis machine
can cut linearly along the X axis (width), the Y Axis (length) and Z axis
(depth). Additional axes simply add rotation to the tool along the X, Y or Z
axis which allows for more complex parts to be manufactured.
Prior to the invention of computers, these axes were controlled manually by a
human operator. Today, a 3D model is translated into a series of step-by-step
instructions the CNC machine can use to create the model out of metal or
plastic. It's a highly automated process that allows the machine to move the
tool along its various axes.
