‘Service and system configuration’ allows functions to be selected according to the operator’s requirements during the initial installation of the system. A single Profilemaster sensor module can usually provide the desired product contour. A two-module configuration allows many types of profiles to be 100 per cent measured. Four modules are required to fully measure profiles with indented areas. Zumbach Electronic AG – Switzerland Fax : +41 32 356 04 30

Software modes essential to accurate in-line measurement

The dimensions of profiles made of metal, plastics or rubber must be continuously measured and monitored in the manufacturing process. Samples are commonly measured on a profile projector or similar apparatus, but this method can be inaccurate because of the many steps requiring exact and careful handling. Optical inline measuring technology using standard laser diameter gauges or CCD cameras cannot measure indented or concave parts of profiles such as connecting rails or grooves. manufactures Profilemaster ® systems as a practical solution to this problem. Up to four laser/ camera modules continuously measure the cross section of the moving profile online. One or multiple lasers (depending on the number of modules) project a visible laser contour around the profile, and this is registered by matching CCD cameras. A powerful PC based processor adds together the partial pictures made up of straight lines and radii, to provide a cross-section of the profile. All relevant dimensions, including width, height, angle and radii, are combined to form the full cross-sectional picture. Nominal values for the profile can be directly imported from the CAD construction, which allows easy programming. Changes in speed and twist within normal limits have no effect on the fi (Below) Zumbach’s Profilemaster measuring unit; and (bottom) a typical display from Profilemaster Zumbach, Switzerland,

measurement. Nearly all the geometrical data of a profile can be collected, and an operator-friendly graphic display of this data allows the product to be monitored during the production. The software developed for the Profilemaster has three working modes. ‘Operation’ mode is used for measurement during production. ‘Entering product data’ involves the entry of measurement requirements and definition of the processing method.
