Every part that is made in the shop is originally designed on a computer or a blueprint drawing. In order to lay out the dimensions of a workpiece, a designer uses a coordinate system to describe the measurements of each dimension. Figure shows a blueprint drawing that contains these measurements.
Both blueprint drawings and CNC systems rely on these numerical coordinates to determine the location and size of workpiece dimensions. Every location is given a numerical value that places it within the three axes.
A CNC machine can only perform what it is programmed to do. Before a part is made on a CNC machine, a programmer takes the numerical dimensions of the blueprint and turns them into step-by-step instructions. The CNC machine then uses the coordinate system to perform these instructions, one after another, to make the part.
