Heidenhain: Position Display Units (POSITIP 880)

Digital Readouts for Manual Machine Tools

Digital readouts for manual machine tools increase your productivity. You save time, increase the dimensional accuracy of the finished workpiece and enjoy user friendly operation. It plays no role whether you have equipped a new or used machine with a digital readout. HEIDENHAIN digital readouts can easily be retrofitted to any model of machine or type of equipment, whatever the application and number of displayed axes. Practice-oriented functions and cycles are available for various applications. The distance-to-go display feature with graphic positioning aid allows you to approach the next nominal position quickly and reliably simply by traversing to a display value of zero. And POSITIP speeds up small-batch production—repetitive machining sequences can be saved as a program.

Precise manufacturing made easy: Together with linear encoders from
HEIDENHAIN, the digital readouts measure the axis movements directly. The
backlash caused by mechanical transfer elements such as lead screws, racks and gears therefore has no influence.

POSITIP 880 | The programmable readout for up to six axes

The POSITIP 880 is a versatile display unit designed primarily for milling machines, drilling and boring machines and lathes with up to six axes. A separate I/O unit provides switching input/outputs for simple tasks in automation.

Design

The POSITIP 880 is designed as a sturdy upright unit with splash-proof full-travel keypad for use in the workshop. It supports all operations with straightforward interactive menus on its large, easy-to-read color fl at screen.

Functions

The POSITIP provides advanced features beyond those offered by the ND 780 digital readout. The POSITIP supports any axis combination and helps you at 2-D machining operations with its graphic contour monitoring and magnify function. In the milling mode, it supports you in machining and clearing out rectangular pockets while it takes allowances into account during turning.

The programming capabilities of POSITIP make it ideal for small-batch production on conventional machine tools: you can store up to 999 program blocks per program in its memory. Programs are created by either keying them in step by step or generating them through actual position capture (teach-in programming). With the subprogramming capability, you can enter repetitive machining sequences on the same workpiece once only. Fixed cycles keep your programs short and save you programming time.

Data Interfaces

The POSITIP 880 has an RS-232-C/V.24 serial interface for measured value transfer to a PC or printer, for input/output of parameters and compensation value lists, and for diagnostics.

A parallel Centronics interface is also provided for pure measured value output.

Heidenhain: Evaluation Electronics (ND 1400 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 1400 QUADRA-CHEK | The evaluation electronics for manual 3-D measuring machines

The ND 1400 QUADRA-CHEK evaluation unit supports four axes: in addition to the linear axes XYZ it features an auxiliary axis Q solely for angular display. The readout is designed specifically for manual coordinate measuring machines, and can capture two- and three-dimensional features with its measuring computer functionality.

Execution

The ND 1400 series evaluation electronics are characterized by the large color touchscreen. Their enclosures consist of robust, die-cast aluminum.

Functions

The innovative operator guidance provides self-explanatory information about the various functions. It already supports you while setting up the coordinate system (finding the reference system, aligning the part, and specifying the datum).

Predefined features (point, line, circle, slot, rectangle, plane, cylinder, cone, sphere) are available for measurement. The “Measure Magic” function makes measurement especially easy: it selects that feature which best matches the shape implied by the points probed. In addition, you can establish relationships (distances, angles) between all features.

You can create or automatically record measuring programs for repeated parts. The evaluation electronics graphically take you to the next measuring position during program run.

You can also use the ND 1400 to measure 3-D features, such as surfaces, cylinders, cones, etc. The measuring points are probed with a touch probe. If a triggering touch probe is used, the values are transferred automatically. With rigid probing elements a key must be pressed. The measured features can be clearly displayed either in three dimensions or in one of the three projection planes.

Data Interfaces

You use the data interfaces to output measuring points as well as to read and transmit settings, compensation values and programs. The RS-232-C/V.24 serial interface enables communication with a PC. You can connect printers or memory media to the USB port. A list of possible printers is available online.

Clearly Structured Display

The large, color, fl at-panel touchscreen enables simple operation with intuitive operator guidance, since in each mode only those functions actually available are offered for selection. The numeric keypad and the few basic function keys are located in ergonomically favorable positions.

Measuring 3-D Contours

In addition to the fl at geometric features, such as points, lines, circles, etc., you can also use the ND 1400 to measure 3-D shapes, e.g. cylinders or cones. The screen displays the feature in three dimensions. Colored highlighting of each measuring point lets you identify form errors and any filtered measured values at a glance. The ND 1400 also permits 3-D position and form tolerances, such as flatness and parallelism.

Working with the Touch Probe

The ND 1400 also supports you optimally while working with touch probes. You can instantaneously call commercial probing elements (normal stylus, star stylus), as well as rigid and tiltable probing heads, all of which are managed in a library, via the touchscreen. During probing the ND automatically takes the direction of probing into account, as well as the length and diameter of the stylus. Even complex parts can be rapidly measured with the five available coordinate systems.

Point Measurement

The ND 1400 probes the measuring points via the touch probe of the coordinate measuring machine. A triggering 3-D touch probe is connected directly to the evaluation electronics, and the measured value is transferred automatically. With a rigid probing element the measured value must be transferred by pressing a key. You can use the comprehensive input menu to define numerous parameters.
