Mobile 3D surface measuring system for cutting tools based on a collaborative 6-axis robot

近120年来，斯图加特大学机床研究所一直致力于机床、装配、电动工具和工具的设计、仿真和优化以及实验分析等领域的研究和教学。该研究所不仅为金属材料及其合金，也为木材或木基产品、塑料、复合材料以及混杂材料开展了机械加工操作工具和工艺优化的研究和开发项目。除了机床、刀具和加工工艺的模拟设计外，该研究所还非常重视它们的实验分析。这里不仅要测量被测刀具的宏观和微观范围的表面和几何形状，而且要测量用这些刀具加工的各种材料的工件的表面和几何形状。为此，本文应用的移动式三维表面测量系统促进了以下测量方法：轮廓粗糙度测量、面积/体积测量、形状和位置公差、曲面几何、毛刺测量以及直接在机床工作区域内不同刀具尺寸和类型的特殊边缘测量，即不需要打开测量对象。

For almost 120 years, the Institute for Machine Tools (IfW) of the University of Stuttgart has been researching and teaching in the fields of the design, the simulation and the optimization of machine tools, assemblies, power tools and tools as well as their experimental analyses. The research and development projects of the IfW for optimizing tools and processes of machining operations are not only carried out for metallic materials and their alloys but also for wood or wood-based products, plastics, composites as well as hybrid materials.Apart from the simulated design of machine tools, tools and machining processes, the institute also lays great emphasis on their experimental analyses. It is essential here to measure not only the surfaces and geometries of the examined cutting tools in the macroscopic and microscopic ranges but also of the workpieces out of various materials machined with these tools. For this purpose, the mobile 3D surface measuring system applied for here facilitates the following measuring methods: profile roughness measurement, area/volume measurement, form and positional tolerances, surface geometries, burr measurement as well as special edge measurements for varying tool sizes and types directly in the working area of a machine tool, i.e. without unclamping the measuring objects.
