  • Patent number: 7375361
    Abstract: The orientation of a machine 2 relative to a work-piece 10 is manually controlled by means of an alignment device 4. The device 4 includes a light source 24 rigidly attached to a foot 12 that is resiliently movably attached to the main body 18 of the device. The body 18 of the device 4 houses a light detector 26 for detecting a light beam from the light source 24, the position of the region on the detector 26 illuminated by the beam depending on the orientation of the machine 2 relative to the work-piece 10. The operator is provided with feedback on whether the machine 2 is correctly aligned with a target orientation (usually perpendicular to the surface) and concerning the direction of corrective movement required, if any.

  • Patent number: 7217071
    Abstract: In the method, a tool is tested for an aligning fit or an imbalance in a tool spindle. The tool spindle is set into rotation. A light beam is used to check whether the tool wobbles. The tool spindle and the light beam are moved relative to one another until the light beam impinges on the area covered by the wobbling movement and a received signal generated from the light beam has an intermittent signal path for the first time. The then prevailing relative position between the tool spindle and the light beam is evaluated in respect of a non-aligning fit of the tool or in respect of a tool imbalance.

  • Patent number: 7104866
    Abstract: According to a machining device for machining a conductive workpiece (W) by a conductive (T), when the tool (T) contacts the workpiece (W) in machining, there is formed a closed-circuit (C) connecting the tool (T), the workpiece (W), a brush (315), a conductor (311), a main spindle housing (12), a main spindle (11) and again the tool (T in that order. Alternating-current is inducted to the closed-circuit (C) by a high-frequency generator (314) and an exciting coil (312). As a contact state between the tool (T) and the workpiece (W), impedance of the closed-circuit (C) is changed and then the alternating-current is changed, so that induction current is generated at a detector coil (313), thus monitoring and controlling the contact state by way of the induction current.

  • Patent number: 7070509
    Abstract: In an integrated cutting and tapping tool, a part in the form of a strip is held on a strip support with a hole facing a tap carried by a tapping tool. The bottom dead center point of the tap is detected by a feeler associated with a multiplier lever pivoting about a transverse shaft and pulling on a transmission cable whose free end is detected by position detection means. In this way the position detection means may be moved out of the tool platen, so that the plunger and the multiplier lever constitute an assembly that is easy to integrate under the tapping area. The machining of defective tappings is detected in this way.
