I - 1 Fundamentals of Positioning I - 1 Fundamentals of Positioning Datums The workpiece drawing identifies a certain point on the workpiece (example: “a corner”) as the absolute datum, and perhaps one, or more other points as relative datums. The datum setting procedure establishes these points as the origin of the absolute, or relative coordinate systems. The workpiece, which is aligned with the machine axes, is moved to a certain position relative to the tool.
I - 1 Fundamentals of Positioning Absolute Workpiece Positions Each position on the workpiece is uniquely identified by its absolute coordinates. Example: Absolute coordinates of position 1: 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, the tool is moving to the value of the coordinates. Incremental workpiece positions A position can also be referenced to the preceding nominal position.
I - 1 Fundamentals of Positioning Zero Angle Reference Axis The Zero Angle Reference Axis is the 0.0° position. It is defined as one of the two axes in the plane of rotation. The following table defines the Zero Angle where the position of the angle is zero for the three possible planes of rotation.
I - 1 Fundamentals of Positioning Encoder Reference Marks Encoders normally contain one or more reference marks which the 300S Reference Mark Evaluation feature uses to re-establish datum positions after a power interruption. There are two main options available for reference marks; fixed and distance-coded.
