Abstract

In principle, as for a high-precision photo-electric barrier, the Laser-System is capable of monitoring (within the entire machining-range) even the smallest tools for breakage as well as precisely measuring length and diameter of rotating tools. All this can be realized under the rough environmental conditions within a machining center. By measuring tools in the spindle and at operating speed, clamping errors, run out, "flight-circle"-deviations and thermal drift of the machine can be determined and compensated. The integrated electronics react to the shading of the laser beam by each cutting edge and, after having detected the longest cutting edge, transmits the respective information to the machine tool control. The visible red-light laser (wavelength 670 nanometres, output capacit
