Delcam PowerSHAPE 2013功能预览

Delcam PowerSHAPE 2013 提供了更完美的直接建模工具，具有更快的选取功能，更多的逆向工程功能，也更简便，更灵活，更易于控制，可助您极大提高生产力。

PowerSHAPE 2013 可动态反馈显示旋转轴、角度和距离，从而帮助快速进行制造准备和更新。新的选取工具可更轻松地选取实体形面进行修改。

以下是 PowerSHAPE 2013 的一些新功能要览:

• 替换形面，便于设置加工余量或电极间隙

• 完善的实体型芯工具，简化复杂实体区域提取

• 直接捕捉激光扫描仪点数据

• 交互崁套，更有效地使用材料

直接建模 – 替换形面

替换形面功能用相同实体的其它形面，或是单独打开的实体或曲面上的形面来替换当前实体上的所选形面。任何因替换形面而受影响的其它实体形面都可自动延伸并按需要重新裁剪，保持实体闭合。替换形面功能还可用来删除或修改实体中的复杂特征，帮助设置加工余量，或是设置EDM电极间隙。

实体型芯

全新的实体型芯工具能自动选取可全面封闭所选实体形面的最小长方形或圆柱形板坯。选取选取并显示在屏幕后，可使用直观、简便的虚拟抓手对板坯进行交互编辑，得到理想尺寸。可从简单的 Spreadsheet 表单选取板坯。可根据自身需要，设置或编辑这个表单。

直接捕捉点云

逆向工程用户现在可使用激光数字化测量臂来交互采集点云数据。随着激光束扫过零件表面，点云数据可即时显示在屏幕，确保采集到重构零件所需的全部数据。直接捕捉功能支持多种扫描装置，包括 FARO，Romer，Perceptron 和 Nikon。

崁套

崁套功能可最高效地崁套分布零件，最大限度应用每寸原材料。PowerSHAPE 支持 2D 轮廓和 3D 零件崁套，十分适合于复合制造的加工应用。通过简单明了的对话视窗，用户可指定所需的每个部件数量，零件之间的最小间隙等。简单 2D 曲线定义的材料板坯便于保存，并方便重新使用部分用过的板坯，最大限度应用材料。

The 2013 release of Delcam’s PowerSHAPE CAD system includes enhancements to its direct modelling and reverse engineering capabilities that will make the software both more flexible and even easier to use. In addition, the solid and surface modelling options have been made faster and even more robust.

PowerSHAPE provides the most comprehensive range of modelling techniques available in a single CAD program. Having all the different technologies in the same package reduces the need to transfer data between multiple programs and so streamlines the whole product development process. The broad range of functionality makes PowerSHAPE ideal for the re-engineering of existing products into improved designs or for creating specialised items. At the same time, the combination of quick and easy direct modelling options, together with powerful and flexible surface modelling, makes PowerSHAPE the perfect choice for design for manufacture, especially when converting product designs into tooling designs.

The most important new option in PowerSHAPE’s direct modelling functionality is “Replace Face”. This allows a selected face or group of faces to be replaced with another face or group of faces, either from the same solid or from a separate solid or surface model.

In its most basic form, “Replace Face” can be used for offsetting surfaces of the model to provide machining allowances or clearances for electrodes for EDM. It can also be used for more complex modifications to product designs. In all cases, any other faces within the design that are affected by the change are extended and re-trimmed as necessary to maintain a closed solid.

A second new option that will be of particular interest to tooling designers will be the “Solid Core” command. This selects automatically the smallest rectangular or cylindrical shape that will fully enclose a group of solid faces. It can be used to create blanks for the manufacture of electrodes or when modelling slides within moulds to accommodate undercuts. The shapes can be selected from spreadsheets, for example one showing different standard sizes for electrode blanks, that can be edited to each company’s specifications.

The main improvement to the existing direct modelling tools has been a simplification of the selection and editing of faces. Groups of faces can now be selected by surrounding them with a boundary, either by dragging the mouse or by clicking a series of points. Simpler methods have been added to then rotate the selected faces around a point or a cylinder, or to move them along a line.

For reverse engineering, PowerSHAPE now allows point-cloud data to be captured directly. Point data can be displayed on-screen instantly as a laser attachment is passed over the object being scanned. This ensures that all the required information can be captured as any gaps in the data will be apparent immediately.

Another new option in PowerSHAPE 2013 is the ability to perform 2D nesting of 2D profiles or 3D parts. Once the numbers of each component required and the minimum spacing needed between each item has been specified, PowerSHAPE calculates the most efficient layout using the minimum amount of material. The shape of any unused material can be saved so that it can be used for later projects. The nesting option will be important for any company using sheet materials, including those in the press tool, composites and footwear industries, or for laying out multiple 3D parts for effective machining.
