摘要:
A method for verifying completion of a task. Location coordinates of at least one location sensor within a work cell are obtained. At least one sensor is affixed to a tool used to operate on a feature of a structure to be assembled, fabricated or inspected. A virtual object locus is generated based on the location coordinates of the at least one location sensor. The virtual object locus corresponds to a computerized schematic of the structure to be assembled and represents of all possible locations of an object end of the tool within the work cell. One of a plurality of candidate features is identified as the most likely to be the feature operated on by the tool. The identification is based on a probability calculation for each of the candidate features that each respective candidate feature is the feature operated on by the tool.

A method of measuring a feature of an article may include projecting a scale template onto the article at a predetermined size. The method may additionally include projecting a measurement pattern onto the article. An image containing the feature, the scale template, and the measurement pattern may be recorded by the camera. The method may further include determining a scale factor of the image based on the scale template, and determining a size and/or a location of the feature based upon the measurement pattern and the image scale factor.

摘要:
A method of operating a multi-axis machine. The machine linkage is monitored to detect an approach by linkage joint(s) toward singularity. A degree of the approached singularity is determined. The joint(s) approaching singularity are identified. Virtual joints are used to replace the identified joint(s) in a manipulator matrix to modify the manipulator matrix. The modified matrix is used to determine position changes for the linkage links. This method can provide software-based compensation for a wide range of machine configurations, without a priori knowledge of singularities for a given machine.

Rough machining of a workpiece is performed by a numerically controlled machine tool using an adaptive toolpath technique. Material removal rate and machine efficiency are increased by forming a pre-roughing slot in the workpiece along medial axes, and machining the remainder of the workpiece using a toolpath that begins inside the pre-roughing slot and spirals outwardly in smooth curves.

摘要:
A computer implemented method, apparatus and computer usable program product for mapping a position of a physical point on a digital model. The method comprises receiving sensor data for the physical point from a sensor unit and correlating a position of the physical point to the digital model. The computer implemented method calculates an alignment probability for the correlated position and then compares the calculated value to a stored threshold value. If the alignment probability for the correlated position does exceed the predetermined threshold probability, an aligned position is formed. An aligned position of the physical point is stored relative to the digital model, responsive to a store map location command.
摘要:
The apparatus and method of the present invention provide a quick, simple and accurate manner in which to measure the dimensions or characteristics of a hole without contacting the hole. The apparatus and method of the present invention also automatically detect different materials defining the hole and, therefore, the location of the interface where the materials meet. To measure the characteristics of the hole, the apparatus and method measure the intensities of the light reflected off the hole wall. In addition, the light directed toward the hole wall by the optical fiber may be of the type, such as collimated or focused, to provide distinct reflections that are received and measured by the optical receiver to supply accurate measurements of the hole characteristics.
