Heidenhain: Evaluation Electronics (ND 2100 G GAGE-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 2100 G GAGE-CHEK | The evaluation unit for multipoint inspection apparatuses

The ND 2100 G GAGE-CHEKs are versatile metrology displays for measuring and inspection tasks in manufacturing and quality assurance. With inputs for up to eight encoders, they are predestined for multipoint measurements from simple pass/fail detection up to complex SPC evaluation.

Execution

The ND 2100 G evaluation units have a robust, die-cast aluminum enclosure, and a keyboard suited to their environment. A large, graphic, color screen displays the measured values, the soft-key row and other information.

Functions

The inputs can be assigned and combined as desired with mathematical, trigonometric or statistical formulas. This makes it possible to measure even complex dimensions such as thickness, flatness, volume and more. The results are displayed numerically or graphically as a color bar graph or a dial, or archived for statistical process control (SPC). The GAGE-CHEK can be configured for basic or advanced applications. Soft keys and hot keys can be adapted as required. The minimum/maximum function of the ND 2100 G evaluation unit monitors and stores the highest and lowest measured or calculated value. Warning and tolerance limits can be assigned to each display value. Results outside of the tolerance are marked with a different color. An acoustic alarm sounds simultaneously. Tolerance values, SPC parameters and custom formulas are stored for individual parts. GAGE-CHEK can thus manage up to 100 parts with up to 16 visible and 16 invisible measurands. The rapid acquisition of measurement data makes the monitoring of dynamic events, such as the eccentricity of a rotating shaft, possible.

Data Interfaces

The GAGE-CHEK features various interfaces for communicating with parent systems:

DRO View

The display values appear in large, easy-to read numbers. Values outside the tolerance are color-coded, immediately notifying you of errors.

Bar Diagram

You can select to have the values shown as a color-enhanced vertical or horizontal bar graph. The defined warning limits and tolerance limits provide instant feedback. If these limits are exceeded, the color of a bar changes from green to yellow or red, informing you explicitly of critical dimensions.

SPC and Data Storage

GAGE-CHEK includes integrated SPC studies such as mean value charts (X bar) and range charts (R). Min, max, sigma, cp and cpk are also calculated, and are clearly displayed as a graph or histogram. Historical raw data can be saved in a tabular numeric display. Each dimension and all data are time and date stamped.

Formulas and Combinations

You can use mathematical and trigonometric formulas, as well as logical conditions, to combine individual measured values or measurement sequences with each other, and so create complex calculations. This can be used, for example, to calculate and display the circumference of a turned part, the volume of a cube, or the angle between two cams, and also to assign tolerance limits to these values.
