摘要： A method for laser engraving a three-dimensional image into a workpiece includes providing a plurality of pieces of artwork which form a composite three-dimensional image. Each piece of artwork corresponds to a particular layer of material to be removed from the workpiece. The pieces of artwork are sequentially read by laser system program software which translates the lines on each piece of artwork into signals corresponding to laser paths. The signals are received by the laser system control assembly for directing the laser beam along the workpiece in a layer-by-layer relationship corresponding to the sequentially read pieces of artwork. The use of the plurality of pieces of artwork allows for a layer-by-layer removal of material in the workpiece such that the power of the laser need not be continuously adjusted according to the depth of penetration into the workpiece. The method allows for various engraved images to be presented having various sloped surfaces therein.

摘要： Methods and systems for automating the control of fluid jet orientation parameters are provided. Example embodiments provide a Dynamic Waterjet Control System (a “DWCS”) to dynamically control the orientation of the jet relative to the material being cut as a function of speed and other process parameters. Orientation parameters include, for example, the x-y position of the jet along the cutting path, as well as three dimensional orientation parameters of the jet, such as standoff compensation values and taper and lead angles of the cutting head. In one embodiment, the DWCS uses a set of predictive models to determine these orientation parameters. The DWCS preferably comprises a motion program generator/kernel, a user interface, one or more replaceable orientation and process models, and a communications interface to a fluid jet apparatus controller. Optionally the DWCS also includes a CAD module for designing the target piece. In operation, the motion program generator receives input from the CAD design module and the user interface to build a motion program that can be forwarded to and executed by the controller to control the cutting process. The replaceable models provide the motion program generator with access to sets of mathematical models that are used to determine appropriate jet orientation and process parameters. For example, in some environments, these equations are used to generate the x-position, y-position, standoff compensation value, lead angle, and taper angle of each command. The DWCS also provides two way communication between itself and the controller. The controller functions are used, for example, to display the cutting path in progress while the target piece is being cut out of the workpiece. They are also used to obtain current values of the cutting apparatus, such as the current state of attached mechanical and electrical devices.
摘要翻译：提供了用于自动化控制流体射流取向参数的方法和系统。示例性实施例提供了一种动态水射流控制系统（“DWCS”），以根据速度和其它过程参数来动态地控制射流相对于被切割材料的取向。取向参数包括例如沿着切割路径的射流的x-y位置以及射流的三维取向参数，例如切割头的间隔补偿值和锥形和引导角。在一个实施例中，DWCS使用一组预测模型来确定这些取向参数。 DWCS优选地包括运动程序生成器/内核，用户界面，一个或多个可替换的定向和过程模型，以及到流体喷射装置控制器的通信接口。可选地，DWCS还包括用于设计目标件的CAD模块。在操作中，运动程序生成器接收来自CAD设计模块和用户界面的输入，以构建运动程序，该运动程序可被转发到控制器并由控制器执行以控制切割过程。可更换型号为运动程序生成器提供访问用于确定合适的喷射方向和过程参数的数学模型集。例如，在某些环境中，这些方程用于产生每个命令的x位置，y位置，平台补偿值，引导角和锥角。 DWCS还提供了自身与控制器之间的双向通信。例如，当将目标件从工件切出时，使用控制器功能来显示正在进行的切割路径。它们也用于获得切割装置的当前值，例如附接的机械和电气装置的当前状态。

摘要： An apparatus and method for forming a three-dimensional object within a block of transparent material by using a laser beam. This is useful in the field of rapid prototype manufacturing (RPM) in which a computer-generated CAD file defining an object may be converted directly to the described object. A CAD surface model is sliced and the data from the sliced model used as input to a numerically controlled machine. Because only the surface of the volume being cut from the solid block must be scanned by the laser beam, this process is much faster than other RPM manufacturing techniques where a laser beam must scan every point inside the shape being formed. Objects having complex geometries and/or hollow interiors may readily be formed using the disclosed apparatus and method.

摘要： Computer based methods, systems, and techniques for planning and generating machining paths for a tool that manufactures a three dimensional object having beveled or “compound” contours from a workpiece. A computer aided design (CAD)/computer aided manufacturing (CAM) system creates intermediate machining path surfaces that extend based on a CAD solid model representing the geometry of the object to be manufactured. The intermediate machining path surfaces extend to a shape that simulates a cutting beam (e.g., a waterjet, a laser beam, etc.) of the tool. For a flat workpiece, the machining path surfaces may extend from a top surface of the workpiece, which is a tool beam entrance surface, to a bottom surface of the workpiece, which is a tool beam exit surface. An operator is able to visualize the cuts to be made and the actual finished object geometry, without requiring the creation of multiple CAD solid models.

This invention is particularly useful in the field of rapid prototype manufacturing (RPM) wherein a computer-generated CAD file defining an object may be converted directly to the described object.

Because only the surface of the volume being cut from the solid block must be scanned by the laser beam, the inventive process is much faster than other RPM manufacturing techniques where a laser beam must scan every point inside the shape being formed. This saves both time and electrical energy over methods of the prior art. Objects having complex geometries and/or hollow interiors may readily be formed using the disclosed apparatus and method.

摘要： A method for laser engraving a three-dimensional image into a workpiece according to color shades found in an original piece of artwork. The original piece of artwork is separated into a plurality of illustrations with each illustration corresponding to a particular layer of material to be removed from the workpiece in accordance with a selected color shade found in the original artwork. The illustrations are sequentially read by laser system program software which translates the lines on each illustration into signals corresponding to laser paths. The signals are received by the laser system control assembly for directing the laser beam along the workpiece in a layer-by-layer relationship corresponding to the sequentially read illustrations. The use of the plurality of illustrations allows for a layer-by-layer removal of material in the workpiece in correspondence with the various color shades on the original piece of artwork. As such the power of the laser need not be continuously adjusted according to the desired depth of penetration into the workpiece. The method allows for various images to be engraved into the workpiece in accordance with the original artwork.

摘要： Systems and methods for providing real-time modification of cutting process programs using feedback from one or more sensors which measure one or more operational parameters of a cutting process and/or cutting apparatus. The sensor readings may be used to provide real-time modification of a motion program after such motion program has been provided to a motion controller. Examples of such operational parameters may include waterjet pump supply pressure, the abrasive mass flow rate, the force of the waterjet on the target piece, etc. The systems and methods discussed herein also utilize a cutting algorithm or program to calculate actual cut quality based on one or more sensor inputs, and to generate warnings or system shut-downs accordingly. The systems and methods discussed herein also utilize inspection devices to inspect coupons or first articles, and use the inspection data to autonomously modify motion programs and/or cutting process models without user intervention.
