    Measurement and control tasks: length or surface measurement, axis control, laser signal acquisition, device control, etc.
    ADDI-DATA measurement and control systems enable you to acquire various sensor data like transducer, laser, encoder etc. In addition to diagnostic tasks, the robust systems can also be used for control tasks like switching signals on or off.

    Product applications for tool making and machine building industry

    Quality control of balls for ball-bearings

     

    Tool making and Machine building Industry

    Challenge

    On a grinding machine balls for ball-bearings are ground. After the grinding process the balls are to be measured directly on site and evaluated. Possible correction values for the production process are to be transferred directly to the PLC which controls the grinding machine. For this purpose a very robust measurement technology is required as the measurement is effected on the production site. The application controls whether the dimensions of the balls lie within predefined parameters or not. If not, the PLC is to initiate the necessary corrections.

    Optimisation of the press process

     

    Tool making and Machine building Industry

    Challenge

    In order to optimise the press process and to reduce defective parts the press depth of a press shall be monitored cycle-dependently. As an installation close to the press is necessary, the system has to be resistant to shocks and vibrations. Furthermore, the measurement system must be easy to handle and allow a fast change of dies.

    Exact positioning of a magnetic resonance tomograph

     

    Tool making and Machine building Industry

    Challenge

    The table of a magnetic resonance tomograph (MRT) for 3D scans is to be positioned precisely in order to be able to correctly assign the pictures to each position. A reference run is not possible as this would cause a considerable delay after switching on the MRT.

    Control of rotary folding machines

    Tool making and Machine building Industry

    Challenge

    In rotary folding machines a precise movement of the paper during the work process is necessary to avoid that the paper gets torn. The challenge is the exact positioning of the secondary axes in a way that they can precisely and continuously execute the predefined machining pattern, even at high speed.

    Test device for gear wheels for watches

     

    Tool making and Machine building Industry

    Challenge

    A manufacturer of watches is looking for new measurement electronics that are suitable for a manual testing device as well as for a transportable solution for the measurement of the surface of gear wheels. Several points are to be measured. The existing transducers with µAPP signals shall continue to be used as they are very expensive because of their high precision.

    Active vibration damping

     

    Tool making and Machine building Industry

    Challenge

    During the manufacturing of gear wheels, the machine tool generates vibrations which lead to inaccuracy in the production process.

    Measurement of spherical roll

     

    Tool making and Machine building Industry

    Challenge

    Length and maximum diameter of a spherical roll are to be detected. For this, a system consisting of pairs of transducers facing each others is mounted on a ring, through which the object is pulled. For each transducer pair an identical limit value is predefined. A PLC controls the measurement process.

    Monitoring of a tools motor current

     

    Tool making and Machine building Industry

    Challenge

    During the production process of gear wheels, the tool seizes. Thus the motor current increases abruptly. In order to avoid damages on the tool, the work piece and the machine, the motor current shall be measured and the force with which the tool touches the work piece shall be established.
