1 Introduction 1.2 Fundamentals of NC Absolute workpiece positions Each position on the workpiece is clearly defined by its absolute coordinates. Example: Absolute coordinates of the position ➀: X = 20 mm Y = 10 mm Z = 15 mm If you are drilling or milling a workpiece according to a workpiece drawing with absolute coordinates, you are moving the tool to the coordinates. Incremental workpiece positions A position can be referenced to the previous nominal position: i.e. the relative datum is always the last programmed position. Such coordinates are referred to as incremental coordinates (increment = growth), or also incremental or chain dimensions (since the positions are defined as a chain of dimensions). Incremental coordinates are designated with G91. Example: Incremental coordinates of the position ➂ referenced to position ➁ Absolute coordinates of the position ➁ : X = 10 mm Y = 5 mm Z = 20 mm Incremental coordinates of the position ➂ : IX = 10 mm IY = 10 mm IZ = –15 mm If you are drilling or milling a workpiece according to a workpiece drawing with incremental coordinates, you are moving the tool by the coordinates. An incremental position definition is therefore intended as an immediately relative definition. This is also the case when a position is defined by the distance-to-go to the target position (here the relative datum is located at the target position). The distance-to-go has a negative algebraic sign if the target position lies in the negative axis direction from the actual position. The polar coordinate system can also express both types of dimensions: • Absolute polar coordinates always refer to the pole I, J and the angle reference axis. • Incremental polar coordinates always refer to the last programmed nominal position of the tool.
