Position specifications in the form of Cartesian coordinates
To simplify things, we will only consider one plane of the coordinate system in the following
example, the X/Y plane:

Points P1 to P4 have the following coordinates:
Position Coordinates
P1 X100 Y50
P2 X-50 Y100
P3 X-105 Y-115
P4 X70 Y-75
Example: Workpiece positions for turning
With lathes, one plane is sufficient to describe the contour:
