    Abstract: A method of generating a part program for use in an image-measuring system and in an image-measuring instrument is provided. The method can be employed easily by an operator without complicated operations to efficiently generate a part program for a CNC image-measuring instrument. This method facilitates the operator to visually identify a work to be measured, through reading CAD data of the work; setting measurement conditions and a positioning coordinate system; calculating a size of the work when it is practically imaged; and displaying an image of the CAD data with the same size. Then, through setting tolerance information; and selecting an objective graphic to be measured, an edge detection tool is placed for a graphic element of the objective graphic selected.

  • Patent number: 6810300
    Abstract: A method of designing a product for use on a body used to develop a preferred product configuration using a computer-based virtual product development and testing system. A virtual wearer sub-model is created of the body and a virtual product sub-model is created of a product for use on the body. An environment sub-model is generated so that environmental factors affecting the product or the body are also used in designing or evaluating the product. Instructions defining how the wearer sub-model, the product sub-model and the environment sub-model interact are introduced in an interaction model. The sub-models and the interaction defined by the interaction model are then combined to create a virtual use model simulating the use of the virtual product sub-model by the virtual wearer sub-model. The use model determines the forces, deformations and stresses caused by movement and interaction between the virtual wearer sub-model and the virtual product sub-model using numerical method analysis.

  • Patent number: 6704684
    Abstract: The invention relates to a method for detecting measurement data on coordinate measuring and digitalizing machines. When the measuring times of the coordinate measuring machine and the sensor are determined by an electric signal (trigger), the equality thereof can be guaranteed and the influence of signal propagation delays can be excluded. The nth sensor information always corresponds to the nth machine information. Allocation is made easier when each value detected at a measuring time obtains an identifier. In one embodiment, surface points of a free forming surface can be detected during movement of the sensor on the coordinate measuring machine and by means of a measuring sensor. The measuring times are determined by an electric signal that is produced by the sensor and is transmitted to the coordinate measuring machine. The signal triggers distance measuring of the sensor as well as the output of the current machine position.

  • Patent number: 6640202
    Abstract: An apparatus, method, and system for determining the shape of a three dimensional object. In a preferred embodiment, the apparatus includes an array of sensors and elastic connections between the sensors within the array. When placed over a three dimensional object, the array of sensors deforms to conform to the surface topology of the three dimensional object. The sensors are connected to a data processor in which the data from the sensors is taken to construct a three-dimensional representation of the actual physical three dimensional object.

  • Patent number: 6633831
    Abstract: Methods and systems for monitoring semiconductor fabrication processes are provided. A system may include a stage configured to support a specimen and coupled to a measurement device. The measurement device may include an illumination system and a detection system. The illumination system and the detection system may be configured such that the system may be configured to determine multiple properties of the specimen. For example, the system may be configured to determine multiple properties of a specimen including, but not limited to, critical dimension and a thin film characteristic. In this manner, a measurement device may perform multiple optical and/or non-optical metrology and/or inspection techniques.

  • Patent number: 6625565
    Abstract: The present invention provides a system and method for performing three-dimensional surface measurements of a path length along a surface. The method for determining the path length along the surface of a three-dimensional object includes the step of first selecting a first and second point on the three-dimensional surface. A plane is then defined which contains both the first and second points. A determination is then made to find the shortest path curve between the first point and second point which is defined by the intersection of the three-dimensional object with the plane. This path length is recorded for future comparison. A series of subsequent planes is defined that contains the first and second point, wherein these planes are rotated at an angle to each other. A determination is then made for the shortest path length associated with each subsequent plane. The overall shortest path length is the minimum of these recorded path lengths.

  • Patent number: 6615158
    Abstract: A system and method for analyzing a surface. The system includes a computer including a CPU and a memory medium operable to store programs executable by the CPU to perform the method. The method may include: 1) receiving data describing an n-dimensional surface defined in a bounded n-dimensional space, where the surface is embedded in an m-dimensional real space via embedding function x( ), and where m>n; 2) determining a diffeomorphism f of the n-dimensional space; 3) computing the inverse transform f−1 of the diffeomorphism f; 4) selecting points, e.g., a Low Discrepancy Sequence, in the n-dimensional space; 5) mapping the points onto the surface using x(f−1), thereby generating mapped points on the surface; 6) sampling the surface using at least a subset of the mapped points to generate samples of the surface; and 7) analyzing the samples of the surface to determine characteristics of the surface.

  • Patent number: 6611791
    Abstract: (A) The surface shape of an object (1) is measured by varying the position and/or direction of measurement, and a plurality of sets of partially measured data (2) including the common parts (2a) are acquired, (B) for all the partially measured data (2), the overlapped ranges (3a) of the adjacent common parts (2a) are determined within the measurement error ranges (3), (C) when there are no superposition ranges (3a), it is decided that a combination is not possible, and (D) when there are overlapped ranges (3a), the common parts of each set of partially measured data are combined within the ranges. Thus, combined data can be created at a high accuracy from a plurality of sets of partially measured data based on a small number of repeated calculations.

  • Patent number: 6571196
    Abstract: In a size inspection method and a size inspection apparatus, even when a measurement object has a contour having sizes not to be easily measured and having a contour not to be easily determined, the contour and the sizes can be determined. A contour of the inspection or measurement object is detected, and positions detected are registered to constitute a group of registered positions. At measurement or inspection, a comparison is conducted with the group of registered positions in a measurement direction to extract correlation data within a measurement range. A position having highest correlation with the group of registered positions is set as a position on one side of a size measurement location. Resultantly, sizes are measured and a contour is inspected.

  • Publication number: 20030088383
    Abstract: Annular grooves are formed on both end surfaces of a recording drum to be rotated, and two balance weights are disposed inside each of the annular grooves. The balance weight is composed of a magnet, and is attracted to the end surface of the recording drum by its magnetic force. The two balance weights are arranged at a predetermined attaching angle such that an unbalance force caused by centrifugal forces developed by a plate, a movable clamp, and so forth is canceled. Every time the size and the mass of the plate are changed, the positions of the two balance weights are adjusted, so that forced vibration in the recording drum is restrained.
