A method for aligning a laser projector for projecting a laser image onto a work surface is provided. The method includes providing a laser projector assembly with a laser source for projecting a laser image onto a work surface, a secondary light source for illuminating the work surface and a photogrammetry device for generating an image of the work surface. The method also includes affixing reflective targets onto the work surface and transmitting light from the secondary light source toward the work surface and reflecting light toward the photogrammetry device. The method further includes scanning the targets with a laser beam generated by the laser source for reflecting the laser beam toward a laser sensor and calculating a location for projecting the laser image onto the work surface from the reflected laser beam.

The invention relates to a device for monitoring the contact of a workpiece (1) or tool on a spindle (2) of a machine tool, which device has a contact surface (3) for the workpiece (1) or tool. At least one measurement nozzle (4) is arranged in the region of the contact surface in order to produce a fluid flow directed away from the contact surface (3). Upstream of the measurement nozzle, the fluid flow is conducted through a vacuum nozzle, which can comprise a jet nozzle (7c) and a collector nozzle (7b). When the fluid medium flows through the vacuum nozzle, the vacuum nozzle produces a negative pressure in a negative pressure chamber (9c). A pressure sensor (6) or pressure switch senses a measurement pressure (p3) in the negative pressure chamber.
