Metrology frames have proven to be an excellent tool for improving the accuracy of machine tools, and because of the small sizes and travels involved, they may be an excellent fit for micro/meso-scale machine tools. We have developed a metrology frame and incorporated it into a benchtop 3-axis milling machine. We have conducted tests to assess the ability of the metrology frame to more accurately measure tool position relative to the workpiece, and we have implemented these measurements for position compensation through two different methods. Linear displacement, straightness, and squareness measurements with and without compensation reveal across the board improvements, in one case by as much as 92%.
