this citation summarizes a one-page announcement of technology available for utilization. a method was developed for grinding and lapping single-crystal, single-point diamond tools to specific geometries with a chip-free cutting edge for producing mirrorlike surfaces on nonferrous materials. for quality assurance purposes, it became necessary to develop an improved method for lapping the diamond tools to chip-free cutting edges when viewed at 480 times magnification. also, measuring techniques were developed that would assure the user of very accurate and repeatable tool geometries. the information gathered should be useful to engineers and fabricators of reflective optic products and to fabricators of gem-quality diamond cutting tools, capable of machining mirrors with a surface finish of 1.3 nm peak-to-valley. ...for additional information: contact: office of technology applications, information service, oak ridge national laboratory, p.o. box y, oak ridge, tn 37831, (615)574-3896. for publication, request support package on 491/y/tn
