A 360° circular optics is advanced into the bore and scans its inside surface. Circumferential lines in the bore are represented as rings in the image. This allows for the generation of an undistorted und complete image of the inner surface of the bore. Due to the high scanning rate, the IPS100HR can be advanced rapidly, which allows for short inspection cycle times.
The surface of the full cylinder bores in crank cases are tested fully automatically at the line cycle time (35-60 seconds). The testing system recognizes all surface defects such as blowholes, furrows etc. The system can test honed and rough-honed surfaces as well as surfaces such as the ones that occur, for example, in the preliminary stage of LDS coatings; in other words, all surfaces that occur in practice.
A very special and unique Hommel-Etamic test technology is used for this purpose; the IPS-100 internal test sensor. This sensor is inserted into the bore for testing and scans the inner surface seamlessly. One of the major advantages of this process is that no rotational movement is required, resulting in a very brief image exposure time of 5-7 seconds per bore. Experience shows that the IPS-100 generates high-quality, high-contrast and high-resolution images that the system software evaluates fully automatically. The software is very user-friendly and simple to operate. The benefit of testing from an economic viewpoint is that expensive visual checking by testing personnel is no longer necessary. This ensures that testing is user-independent and objective. Complex and precise classifications of the surface defects are performed simultaneously, resulting in a defined level of quality without components being discharged unnecessarily as NOK when they are actually within the specification limits. For example, porosities are evaluated according to characteristics including size, number, frequency, cluster formation and other statistical characteristics. The system also automatically produces result documentation in the shape of individually configured test statistics.
