The NIST Gage Block Calibration Software System is a complete calibration system with custom, integrated software to calibrate and measure high-precision, quality gage blocks as individual blocks or sets, both English and metric. The calibration system has software programs that enable the NIST technical staff to create and maintain measurement history and related information and statistical process control of NIST's and its gage block calibration customers' gage blocks. These software programs provide for measuring gage blocks using interferometric techniques and doing intercomparison using an opposed head electro-mechanical comparator with automatic data acquisition. The accessory programs enable the NIST technical staff to configure system resources, calculate or estimate elastic deformations, and edit files. This calibration system conducts calibrations and measurements that meet the requirements of MIL-STD 45662A, ANSI/NCSL Z540-1-1994, and ISO 9002-94. |
