摘要： Methods and systems for position sensing are disclosed. In one embodiment, a method includes measuring at least three discrete point positions associated with a first component using at least one transmitter having a known position and orientation and in a line of sight with the three discrete point positions, the three discrete point positions having known distances relative to one another. The method computes a current position and orientation of the first component using data provided by the at least one transmitter and the three discrete point positions, along with position and orientation data from a last known location of the first component assuming that no sudden position changes since the first component has moved from the last known location. The first and second components may be a workpiece and a tool that performs a manufacturing operation on the workpiece.

摘要： A computer implemented method, apparatus and computer usable program product for mapping a position of a physical point on a digital model. Sensor data for the physical point is received from a sensor unit and a position of the physical point is correlated to the digital model. An alignment probability for the correlated position is calculated and the calculated value is then compared to a stored threshold value. If the alignment probability for the correlated position does exceed a 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： 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.

摘要： 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.
