An apparatus for obtaining a desired cut in a workpiece and a method of using the same is provided. The apparatus has a base with a cutting member moveably coupled thereto. A scanner is coupled with the base for scanning the profile of the workpiece desired to be cut. A computing device may use information from the scanning process to control transverse and longitudinal stepper motors to move the cutting member through a desired cutting path to achieve a cut based on the profile of the workpiece, such as a cope cut. A user can store profiles of previously scanned workpieces in a memory component of the computing device.

Bei einem Verfahren zum Vermessen einer sich etwa in einer Längsrichtung erstreckten Raumkontur mittels einer optischen Abtasteinrichtung, die die Koordinaten (X, Y, Z) von Abtastpunkten bestimmt, die wie die Raumkontur in der Oberfläche eines Formkörpers liegen, wird die Abtasteinrichtung linear und zumindest annähernd senkrecht bezüglich des Verlaufs der Raumkontur über diese hinweg bewegt und die Koordinaten einer Folge von Punkten bestimmt, die auch in den der Raumkontur benachbarten Flächen liegen. Als zugeordneter Raumpunkt wird der Schnittpunkt der beiden Flächen bestimmt, der zumindest annähernd parallel zur ersten Abtastebene die Raumkontur längs einer zweiten Abtastebene abtastet und den zugehörigen Raumpunkt bestimmt. Die längs der durch die beiden Raumpunkte festgelegte Richtung wird eine erneute Abtastung senkrecht zu dieser Richtung vorgenommen.

In a copy control device wherein a model (6) and a work are moved relatively with a tracer head (4) and a tool in an X - Y plane, measured distance values to the surface of the model, which are detected by first and second non-contact detectors (5a, 5b) obliquely mounted on the tracer head (4) rotatable about a Z axis are periodically sampled to obtain the coordinate values of measured points on the surface of the model, a normal vector (Nm) on the surface of the model is calculated from three coordinate values out of four measured points (P1n-1, P1n, P2n-1, P2n) successively obtained by the both detectors, and the tracer head is rotated so as to move along a projection (N1n) of the normal vector (Nn) on the X - Y plane, so that measuring axes of the detectors are controlled to be approximately vertical to the surface of the model. After two points are selected from four measured points, such a point is selected out of the remaining two measuring two points as a third point that satisfies a condition that a point of intersection between a perpendicular from such a point to a straight line passing through the previously selected two points and the above-mentioned straight line is interposed between the previously selected two points, and that satisfies a condition that the length of the above-mentioned perpendicular is larger than a predetermined value.

A digitizing controller which corrects digitized data and outputs smooth data along an original profile route. Operation means (101) adds coordinate data for indicating the profile route on a model surface to a measured displacement at a profile measurement point of a detector, and calculates coordinate data about a digitized model surface. Correction means (102) corrects the coordinate data at these profile measurement points to approximated data derived from new coordinate points on the profile plane containing the profile route. The corrected coordinate data are outputted as smooth digitized data along the original profile route.

There is disclosed a method for the plasma arc welding of corrugate membranes, which can prevent a welding failure from occurring around the corrugate portion. In this welding method, NC data for robot control are modified so as to gradually change a torch angle around the R portions at a rate not greater than the maximum angular velocity and increase a welding speed around the R portions of foot regions of corrugate portions 1B and 2B and the R portion of an apex 22 before a welding torch 12 reaches the R portions. Three parameters are prepared for determining the deformation of the corrugate portions 1B and 2B in terms of height, width of the foot regions and the swell of the trunk portion. Data indicative of the height and foot width of the corrugate portion measured by a laser displacement sensor 15 are compared with standard corrugation NC data, and the NC data for robot control are modified to correct the height, foot width and swell degree thereof by utilizing the parameters.

A system (10) determines the surface (12) profile of an object (14). Systems of this kind are used in industrial robots, such as automatic welders. The severe operating environment requires a vision system (10) with noise immunity along with accuracy. A beam splitter enables the use of discrete optical detectors which eliminate many problems inherent with previously used detectors, such as diode arrays and TV cameras. Additionally, an automatic gain control (33) alters the intensity of a generated optical beam (18) in response to the reflectivity of the surface (12). These features increase the accuracy and noise immunity of an optical vision system (10) for use in severe industrial applications.
