Laser calibration system

for CNC, CMM and measuring machinesprecisionprocess

The LaserTRACER-NG was developed for calibration, monitoring and accuracy enhancement of measuring machines and machine tools. It is a self-tracking laser interferometer that automatically tracks a reflector, and hence allows for the identification of geometrical deviations with highest precision. Unrivaled accuracy In contrast to conventional measurement devices, the LaserTracer features an unprecedented accuracy of the center of rotation thanks to a patented measurement technique: A sphere with a form deviation of just 50 nanometers is used as an optical reference for the interferometer. As a consequence, the mechanical errors of the rotation and swivel axes are fully compensated. The measurement process: fast and effective For measurement execution, the LaserTracer is stationary placed at several different positions inside the working volume of the machine. Then, the reflector is mounted to the tool or probe. In the following automated measuring process, the LaserTracer tracks the actual path of the machine in its entire working volume. Meanwhile, the system acquires highly precise measurement values that are processed by our software packages TRAC-CAL and TRAC-CHECK for calculating and analyzing the machine errors with sub-micron accuracy. TRAC-CAL: Calibration of CMMs and machine tools The user-friendly software TRAC-CAL guides the operator through the measurement process. Combined with the LaserTracer, the software determines all systematic geometrical deviations of coordinate measurement machines and machine tools. This includes position deviations, straightness deviations, rotational deviations (pitch, yaw, roll), and the squareness of axes to one another.
