Abstract

The Lawrence Livermore National Laboratory (LLNL) Machine Tool Development and Machine Control Groups have recently completed the construction of a small, high-accuracy, two-axis numerically controlled Diamond Turning Machine. The machine, which was assembled from commercially available components, cut its first contoured part two weeks after the project was initiated, and was placed in service after a total of three weeks. One-inch diameter hemispherical aluminum test parts have been cut to an accuracy of 10 microinch (size and contour band) with a surface finish of 1-1.5 microinch rms. The machine, which is limited to parts less than four inches in diameter, has been designated the Baby Optics Diamond Turning Machine (BODTM).
