Product brochure Etalon Laser TRACER-NG The system solution for calibration, compensation and verification of machine tools and coordinate measuring machines

Volumetric compensation Depending on the machine and environmental conditions, the axis errors can be reduced by 50% to 90%.

Etalon Laser TRACER-NG In shortest time to the geometrical fingerprint of your machine The geometric accuracy of machine tools and coordinate measuring machines (CMMs) is one of the most important decision critera, as it has direct impact to the working precision of the machine. The Laser TRACER-NG was developed for the quick and easy monitoring, calibration and compensation of machine tools and CMMs. Etalon builds on a patented, geometrical method, with which also the Global Positioning System (GPS) is working, the so called Multilateration. A sphere with deviations in the nanometer range...

Etalon Laser  TRACER-NG Application cases Manufacturers of machine tools are enabled to efficiently and reliably create a complete geometric fingerprint of their produced machine before use at the customer. As proof of machining ability, the test can be repeated directly on site at the customer or regularly as service offering. Users of machine tools are provided with a tool with which machines of different types can be geometrically monitored. If necessary, volumetric compensation can significantly increase the machine’s accuracy throughout the machining volume to meet demanding tasks....

The Etalon principle Easy and quick calibration, monitoring and accuracy enhancement The unique principle of the measurement with the LaserTRACER-NG: As with the Global Positioning System (GPS), spatial information is obtained by pure distance measurements in space. • The geometrical interaction af all machine axes is captured and with the proven ETALON method, the 6 degrees of freedom (DOF) of all axes and their squareness to each other are determined. • In the entire working volume of a measuring machine or machine tool, spatial accuracies in the submicrometer range can be achieved with...

Etalon Laser TRACER-NG System for verification and calibration of linear and rotary axes Laser TRACER-NG combines highest precision, short measurement time, universal use and full collection of deviation data. For measurement, the compact Laser TRACERNG is placed several times in the machine volume without special fine alignment. Instead of a tool or a probe, a reflector is mounted in the machine. In the subsequent automated measuring process, the LaserTRACER-NG tracks the travel of the machine in its working space. It records highly accurate readings from which the Trac-Cal and Trac-Check...

Reflectors with large working angles (up to 160 °) enable the detection of machine movement directly at the tool center point Linear and rotary axes are subject to geometric deviations in all degrees of freedom, the etalon system can determine this quickly, easily and with high precision and provide correction tables. Sensors measure air temperature, pressure and humidity and correct the laser measurement. Radio-based temperature sensors can optionally record and assess the thermal expansion of the machine axes. The laser source and the electronics for motor control and signal evaluation...

Trac-Cal results Based on the measured data, the deviations of the machine in space and the temperature profile can be checked Trac-Cal then outputs the individual deviations of the machine axes by a press of a button. In multiple visualizations, the 6 degrees of freedom (DOF) of the axes are displayed. For linear axes, these are the deviations of positioning, straightness in both directions, pitch, yaw and roll. For rotary axes these are the deviations of the positioning axial movement, radial movement and the wobbling in both directions. The squareness deviations of the axes to each other...

Trac-Check results If it is less about a detailed analysis of the axis errors, but about a simply comparable, standard-compliant machine inspection or acceptance, Trac-Check provides the necessary information. The software is based on the following current standards. For machine tools • ISO 230-2 (axis parallel lines) • ISO 230-6 (plane and space diagonals) • VDI 3441 • ISO 230-4 (Circular test) Coordinate measurement machines • ISO 10360-2 (including probe testing) The diagrams show the comparison of the axis deviations without (red) and with compensation (yellow), measured at the tool...

Existing standards For machine geometry ISO 230-1 Basic document on machine tool errors and their measurement. Also defines the volumetric accuracy. International standard for linear verification along machine axes. Established worldwide in the industry. Often the main acceptance criterion for machines. Superseded German standard for linear verification along the machine axes (similar to ISO 230-2). Still in international use. Extends the geometric verification according to ISO 230-2 to the plane and space diagonals. Gives good indication of volumetric accuracy. Increasingly adopted in the...
