An interactive reference tool for machine shaft alignment. It provides the common reference tables, specifications and charts for shaft alignment tolerance.

Three main standards are included:
1- NASA Precision Alignment Specs (Ames Policy Directive APD 8830.1)
1.a) Alignment Tolerance for Soft Foot
1.b) Alignment Tolerance for Short Coupling: Horizontal and Angular
1.c) Alignment Tolerance for couplings with spacers

2- Common Tolerance Table with the RPM input for Angular, Parallel, and Spacer Shaft cases
User selects the RPM range, enters alignment values and sees the alignment condition and tolerance range for the machine.

3- Interactive Alignment Tolerance Chart with three regions: Excellent, Acceptable, and Unacceptable.
User enters RPM, offset and angles in both horizontal and vertical directions, and interactively sees the condition of the machine in the chart

Features:
- Shaft Alignment Specification: NASA Standard
- Interactive Shaft Alignment Tolerance Table
- Interactive Shaft Alignment Tolerance Chart in mm and inch
- Email the results
