Surface Plate Auto-Collimation
FOCAL8-152

E. Welsh and R. Sinwell, Westinghouse Electric Corporation,
Cheswick, Pennsylvania

This program is designed to calculate linear deviations of
points along various tracks of a surface plate against a refer-
ence plane through 3 arbitrary points or linear deviations of
points on a machine tool way against a reference line through
2 arbitrary points.

Input data consist of angular deviations in seconds measured
by means of an auto-collimator in combination with a plane
reflector. Output data consist of linear deviations in
micro-inches.
