Heidenhain: Evaluation Electronics (ND 100 QUADRA-CHEK)

Evaluation Electronics for metrological applications

Evaluation Electronics for metrological applications offer numerous functions for measured data acquisition and statistical evaluation of measured values.

QUADRA-CHEK evaluation electronics for profile projectors, measuring microscopes, 2-D and video measuring machines as well as CMMs measure points on 2-D contours, depending on the version either automatically or manually by crosshairs, by optical edge detection or by video camera with real-time display of the live image and integrated image processing. For 3-D contours, such as planes, cylinders, cones and spheres, the measurement points are saved by probing with a touch probe.

In the optional CNC version, they also operate as full-fledged controls for axis positioning and can automatically execute measuring programs.

ND 100 QUADRA-CHEK | The simple evaluation electronics for 2-D geometries

The ND 100s are evaluation units with two to three axes. They function as measuring computers for 2-D geometries. They are suited as entry-level readouts for optical comparators, measuring microscopes and 2-D measuring machines.

Execution

The ND 100 evaluation unit has a monochrome fl at-panel screen for displayed values, dialogs and inputs, graphics functions and soft keys. With its sturdy housing and splash-proof membrane keyboard, the ND 100 is built for the workshop.

Functions

The appropriate combination of defined function keys and context-dependent soft keys always provides you with a clear overview. The innovative operator guidance provides self-explanatory information about the various functions. It already supports you while setting up the coordinate system (aligning the part and specifying the datum).

Predefined features (point, line, circle) are available for measurement. You can apply tolerance values to features and relationships. Only those tolerances actually possible are offered for the selected feature.

The ND 100 readouts measure points on plane (2-D) contours manually via crosshairs.

Data Interfaces

A USB interface enables the evaluation unit to indicate measured values and import or export parameters and tables.

Graphic Display

In addition to the position values, the ND 100 also displays the features graphically. Along with the individual measuring points, the geometrical and arithmetical deviations are also shown, and circles are shown for the minimum and maximum circumscriptions.

Tolerances

You can apply tolerance values to any feature. Only those tolerances actually possible are offered for the selected feature. This means that a point can only be assigned a tolerance check for its position, whereas a circle can be assigned position and shape tolerances.

Defining Features

You can use the QUADRA-CHEK evaluation electronics to define features yourself. For example, this could be a circle whose position and dimensions are exactly defined, or an alignment line that is at a specified angle to a measurable line.
