REQUIREMENTS

Acquisition of a 5 axis scanning system for use with both field/ depot grade and lab grade eddy current data acquisition equipment.

3 linear stages for x, y and z motion with travel ranges of 200mm for the x and y and 100mm for the z stage.

All stages shall have a minimum step size of at least 1 micron, an accuracy of at least +/-1 micron, and a bi directional repeatability of at least +/- 0.5 micron.

There shall also be two goniometer stages to provide for rotation in both the xz and yz planes. This is to allow for scans at various orientations and allow for automated leveling routines.

These stabes shall have at least a 20 degre range of motion with a step size of 1 micro radians and an accuracy of at least +/- 100 micro radians.

These goniometer stages shall have tables with at least 2.5 square inch area or at least 1 side with a length of 2.5 inches.

The completed 5 axis system shall be controlled by a single motion control system to ease implementation.

Linear stage step size: 1 micron Linear Stage Accuracy: +/- 1 micron Linear Stage Bi-Directional Repeatability: +/-0.5 micron Goniometer travel Range: 20 degree Goniometer Step Size: 1 micro radian Goniometer Accuracy: +/-100 micro radian
