  • Page 16: I - 2 Fundamentals Of Positioning

    I – 2 Fundamentals of Positioning Datums The workpiece drawing identifies a certain point on the workpiece (usually 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.

  • Page 17: Actual Position, Nominal Position And Distance-To-Go

    Actual position, nominal position and distance-to-go The position of the length gauge at any given moment is called the actual position, while the position that the length gauge is to move to is called the nominal position. The distance from the nominal position to the actual position is called the distance-to-go (see Fig.

  • Page 18: Absolute Workpiece Positions

    Absolute workpiece positions Each position on the workpiece is uniquely identified by its absolute coordinates (see Fig. I.5). Example: Absolute coordinates of position 1: Z = 20 mm If you are drilling or milling a workpiece according to a workpiece drawing with absolute coordinates, you are moving the tool or length gauge to the value of the coordinates.

  • Page 19: Incremental Position Encoders

    Incremental position encoders Incremental linear and rotary encoders from HEIDENHAIN convert the movements of, for example, a length gauge into electrical signals. A position display unit, such as the ND 287, constantly evaluates these signals and calculates the actual positions of the length gauge, which it displays as a numerical value on the screen.

  • Page 20: Reference Marks

    Reference marks Encoders normally contain one or more reference marks (see Fig. I.9) which the ND 287's 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. Encoders with distance-coded reference marks have marks separated by a specific encryption pattern that allows the ND 287 to use any two pair of marks along the length of the encoder to re-...
