Example
Given the following raw data, use Program VII to calculate 1) out-of
straightness using least-squares fit, 2) parallelism in axis 1, 3)
squareness between axis 1 and 2.
Set-up
5505A Display in X10 mode
Straightness calibration no. = 1 Prism error = 2 arcseconds
Raw Data
Axis 1
Display reading = -3 9 15 25 29 36 42 51 59 72 (pinches)
Machine travel = 0 1 2 3 4 5 6 7 8 9 (inches)
Number of points = 10
Axis 2
Display reading = 5 -12 -25 -38 -40 -48 -59 -62 -74 -88 (pinches)
Machine travel = 0 .5 1 1.5 2 2.5 3 3.5 4 4.5
Number of points = 10
Figure 7.1 shows the out-of-straightness of axis 1 and Figure 7.2
shows the out of straightness of axis 2. Parallelism between axis
1 and axis 2 is displayed between the two figures.
Squareness between axis 1 and 2 is displayed between Figure 7.3 and
7.4.
