摘要： Real time in-process data is collected to determine the contour and position of the interface between dissimilar layers of material. A control system (4) is automatically programmed, based on the determined contour and position of the interface, to automatically control the trajectory of a cutter (30) through a conventional motion control system to separate the dissimilar layers of material. The motion control system controls the cutter movement through, for example, a conventional linear motion device including a servomotor (12), lead screw (32), and slidable carriage (10) that holds the cutter (30).

摘要： In a method of grinding a crankshaft component, the latter is engaged by a grinding wheel and ground until about 50 microns oversize. The wheelfeed is then arrested and gauging of diameter and eccentricity takes place over several revolutions and at a plurality of angular positions. This information is then computed and averaged by a programmable computer means to produce a control signal for finish grinding the component to size.

摘要： A computer (21) processes the time between ultrasonic echoes received at a transducer (19) indicative of the outer radius and wall thickness of a workpiece (10) by subtracting (69) the weighted average (80-90) wall thickness from the weighted average outer radius to generate an internal radius for a large number of points around a spiral slice of the workpiece. The internal radii and angles are converted (69) to x and y coordinates. The centroid (X, Y) of each slice of data indicating workpiece cavity internal radii is determined (71) as twice the summation of the x coordinates and twice the summation of the y coordinates of all of the datum points of the slice. The least squares fit (73) of the X coordinates of the centroids of all of the slices and the least squares fit (74) of the Y coordinates of the centroids of all of the slices are then used to determine the average axis of the cavity of the workpiece. The X^¨B7 and Y^¨B7 coordinates of the end points of the average axis of the cavity are then converted (75) to polar coordinates to permit offsetting the end points of the workpiece commensurate amounts, whereby further machining will cause the internal cavity of the workpiece to end up more nearly centrally located, on average.
