Optical instruments for measuring surface topography are increasingly being used as coordinate measuring machines (CMMs) to allow them to measure complex three-dimensional components. This project will investigate the use of one such instrument based on the principle of point-autofocusing, but with a 5-axis motion system. The fundamental limitations of the techniques acting as a CMM will be determined and quantified. Specification standards that are applied in the CMM and form measurement fields (e.g. ISO 10360, 12181) will be applied, where possible, to multi-axis point-autofocussing and, where not possible, new procedures will be developed. Methods for calculating uncertainties with the instrument will be investigated, including the principle of a virtual CMM applying a Monte Carlo technique. A number of case study components will be measured to showcase the methods developed, with a focus on gear metrology. This project aims to develop measurement and calibration methodologies for the form measurement of complex engineering components.

用于测量表面形貌的光学仪器越来越多地被用作坐标测量机（CMM），以允许它们测量复杂的三维部件。本项目将研究基于点自动聚焦原理的5轴运动系统的仪器的使用。作为CMM的技术的基本限制将被确定和量化。适用于CMM和形状测量领域的规范标准（例如ISO 10360，12181）将在可能的情况下应用于多轴点自动聚焦，如果不可能，将开发新的程序。将研究计算仪器不确定度的方法，包括应用蒙特卡罗技术的虚拟坐标测量机的原理。将测量一些案例研究组件，以展示开发的方法，重点是齿轮计量。该项目旨在为复杂工程部件的形状测量开发测量和校准方法。
