    摘要： Locations in a pattern of a part are evaluated to determine if the locations are interior or exterior to a feature of the pattern. The pattern is used to cut the feature from a material by a laser cutting machine. A location in the feature is rendered into an array stored in a memory so that a value stored at an address in the array corresponding to coordinates of the location is either odd or even as determined by a counting process of the rendering. Then, the location is identified as being interior if the value is odd, and as being exterior if the value is even. The rendering can use modified forms of either rasterization or ray casting.

    摘要： A path of a cutter head of a laser cutting machine is modified to cut features according to a pattern from a material. A no-travel zone that the laser cutter avoids while performing lateral movements between cuts is specified. Locations of the path that cross the no-travel zones are also specified. The path is then modified such that all locations that violate the no-travel zone are removed so that the laser cutter detours around the no-travel zone when performing the lateral movements.

    摘要： A set of costs representing operations of a machine along a set of trajectories connecting a set of exit and entry points on contours of a pattern is determined. Each trajectory represents an operation of the machine proceeding from an exit point with an exit velocity to an entry point with an entry velocity according to dynamics of the machine. The set of trajectories includes at least one trajectory representing the operation along a contour with non-zero velocities at corresponding exit and entry points, and at least one trajectory representing the operation between different contours with non-zero velocities at the corresponding exit and entry points. A sequence of the trajectories optimizing a total cost of operation of the machine tracking the pattern is determined based on the costs, and a set of instructions for controlling the machine is determined according to the sequence.

    摘要： A machine part is guided along a defined movement path over a workpiece surface. The machine part is held at a defined distance from the workpiece surface during this movement. For that purpose, at least one distance sensor is provided that runs ahead of the machine part with a defined lead. A plurality of distance values indicative of a distance between the distance sensor and the workpiece surface are determined along the movement path. A plurality of control values are determined as a function of the distance values. The defined distance is repeatedly adjusted by means of the control values. In accordance with a first aspect, the distance values are determined at measurement points distributed with a first grid spacing along the movement path, while the control values are determined for actuating points distributed with a second grid spacing along the movement path, the first and the second grid spacings being different. According to a second aspect, the machine part has a linear range of activity on the workpiece surface, and the distance between the machine part and the workpiece surface is controlled by means of a distance control value and an angle control value, which are derived from distance values acquired from at least two distance sensors, which are laterally offset from one another.

    摘要： An apparatus 10 and a method 50 for the creation of a tool 40. The apparatus 10 and the method 50 allow for dynamic measurement of the tool 40 as it is being created and further allows for the use of positive feedback to increase the likelihood that the produced tool will be structurally similar to a certain model. The apparatus 10 and method 50 further allow sections of varying thicknesses to be used and provide a technique to create surfaces which further increase the likelihood that the produced tool will be structurally equivalent to a desired and modeled tool.

    摘要： Laser light L is converged at an object to be processed 1 formed from quartz, so as to provide the object 1 with a modified region 7 including a plurality of modified spots S along a line to cut 5. At this time, the laser light L is relatively moved along the line 5 while irradiating the object 1, so as to form the plurality of modified spots S with a pitch of 2 μm to 9 μm along the line 5. This can optimize the pitch between the plurality of modified spots S to be formed, so as to link fractures favorably to each other between the plurality of modified spots S.
