Inspection of the Large Optics Diamond Turning Machine. [Diamond turning machine]
The Large Optics Diamond Turning Machine (LODTM) is of stacked slide design, somewhat resembling a bridge type coordinate measuring machine. In fact, the machine must serve as a measuring machine for the quality control steps of workpiece manufacture since there is not currently another method of measuring the highly aspheric parts manufactured. To calibrate the LODTM and provide an independent check of its accuracy as a measuring machine, a joint effort was mounted with a team from the National Bureau of Standards at Gaithersburg. The LODTM was tested to determine stability, repeatability and accuracy. The results given in this report are just a few of the measurements made to parameterize the performance of the machine
