摘要： The profile of a tool or other object having a flat reference plane is illuminated by interfering beams of coherent light to generate a striped light pattern which at any point deviates from straight lines as a function of the surface spacing from the reference plane. A camera image of the pattern taken at an angle to the beams is processed by an image analysis program which converts the stripes to lines corresponding to light peaks and valleys of the pattern. Tool wear or object profile is determined from the deviation of lines from straight reference lines. The program includes algorithms for identifying peak and valley line segments, determining the segments which are neighbors of other segments, and connecting lines according to a set of rules and constraints which use the data on neighbor segments and the proximity of segment end points.

摘要： The present invention provides for a magnetic apparatus and a method of manufacturing the magnetic apparatus including a magnet having an outer surface and an inner surface opposing each other with the inner surface having a first portion and a second portion integrally connected to and facing each other and utilizing a fluid and a fixture body defining a hole along a fixture axis and a deflector disposed within the hole. The method includes the steps of installing the magnet on the fixture body and securing the magnet to the fixture body. The method further includes the steps of flowing the fluid through the magnet transverse to the fixture axis to form at least one aperture and intersecting the fluid with the deflector to redirect the fluid generally along the fixture axis.
