    摘要: A system for a computer-controlled measurement of workpieces has at least one measuring machine and a device for entering dimensions of workpieces to be produced as parameters into a database. The system is distinguished in that the measuring strategy of a measuring program can be generated by a computer in dependence on the parameters to be read in from the database and the generated measuring program is converted into a machine-dependent control program of the measuring machine.

    摘要: A lens inspection system 10 has two cameras 50, 51 for capturing plan and edge images views of a lens 20 and providing pixel data signals representative of the images. The pixel data signals corresponding to the plan and edge images are analyzed by a computer 70. The computer uses the pixel data signals to calculate the circumference of the image, the lengths of radii to circumferential pixels, and the bevel angle of the lens 20. Such data are compared to data stored in memory 710 and a visual display 74 indicates the difference between the image and the stored data.

    摘要: Apparatus and method for sensing the topography of a workpiece with an electrical arc by measuring a parameter of the electrical arc signal as an electrode is scanned across the surface of the workpiece by a tool manipulator such as a multi-axis robot arm, and processing the measured arc signal in order to derive the three-dimensional topography. The apparatus includes a digital microcomputer which samples the arc signal, stores a plurality of samples in computer memory, computes the average of a predetermined number of samples, and provides correction factors to the host computer of the robot manipulator so that the electrode or a tool carried by the robot can be adaptively positioned. The apparatus senses such features of the workpiece as holes, edges, and slopes of a given magnitude, and passes the location of these features to the host computer for appropriate corrective action. The system provides vertical correction factors as well as workpiece scanning correction factors so that the host can adaptively adjust the position of the electrode or of a separate tool with respect to the workpiece.

    摘要: An arrangement for removing excess material from an object surface, to provide a desired finished surface. Holes are drilled into the object so that the bottoms of the holes lie on the desired finished surface. The holes have a shape so that the observed hole diameter at the prevailing surface of the object is dependent on the hole depth and thereby dependent on the amount of material remaining to be removed between the prevailing surface and the desired finished surface. The prevailing surface is continuously observed and measured, and the depths of material to be removed in a sequence of steps is calculated dependent on the measurements of the prevailing surface and the coordinates of the desired finished surface. As a result of the calculations, the depth of material removed during each step is controlled, so that upon carrying out a sequence of such steps, the surface exposed on the object after the last step has been carried out, coincides with the desired finished surface. The accuracy of the material removal equipment may be substantially less than the accuracy of the finished surface.

    摘要: A method and apparatus is disclosed for setting up fixed and robotic systems by using a robot programmed by design data for a part of structure to simulate a master of same. Envisioned primarily for use in auto body fabrication processes, the invention is generally useable with smaller parts and assemblies. It is considered vitally useful for programmable assembly of bodies or other larger objects where a variety of styles or other considerations virtually preclude effective master parts. The invention sequentially creates, point by point, a master in space, using programmable placement of master surfaces, target points, or cameras capable of evaluating location of assembly robots and other items, generally from target points thereon.

    摘要: In a machine tool, a component such as a grinding wheel acts on a workpiece to form the latter into a circularly asymmetric shape, for example, a crankpin. Movement of the grinding wheel is controlled by a control signal which is derived from theoretical relative positions and positional velocities of the grinding wheel relative to the workpiece. In the course of at least one revolution of the workpiece, the respective positions of the grinding wheel relative to the workpiece are measured for each of a succession of angular positions of the workpiece. The measured positions are compared with corresponding theoretical positions and data indicative of any differences are stored, and then used to modify the control signal during a subsequent revolution of the workpiece so as to compensate for any of said differences and thereby reduce the magnitude of any error which would have resulted from the measured positional differences.
