许多种类的数字化制造都是通过沿着数字化指定的路径精确地移动工具来完成的。这种精确的运动通常是使用计算机控制的多轴工作台全自动地完成的。使用这种方法，只能创建小于定位载物台的对象，而大型载物台可能非常昂贵。我们提出了一种新的方法来精确定位的工具，结合手动和自动定位：在我们的方法中，用户粗略地定位一个框架包含的工具在所需的路径的近似，而设备跟踪框架的位置，并调整框架内的工具的位置，以纠正用户的定位误差在真实的时间。因为自动定位仅需要覆盖人的定位误差的范围，所以该框架可以是小的且便宜的，并且因为人具有无限的范围，所以这种框架可以用于在无限的范围上精确地定位工具。
Many kinds of digital fabrication are accomplished by precisely moving a tool along a digitally-specified path. This precise motion is typically accomplished fully automatically using a computer-controlled multi-axis stage. With that approach, one can only create objects smaller than the positioning stage, and large stages can be quite expensive. We propose a new approach to precise positioning of a tool that combines manual and automatic positioning: in our approach, the user coarsely positions a frame containing the tool in an approximation of the desired path, while the device tracks the frame's location and adjusts the position of the tool within the frame to correct the user's positioning error in real time. Because the automatic positioning need only cover the range of the human's positioning error, this frame can be small and inexpensive, and because the human has unlimited range, such a frame can be used to precisely position tools over an unlimited range.
