Figure 6-69: Traverse File option in the Region(s) menu list.
The external traverse file acts as a transformation matrix between the three
axis logical coordinate system (as specified in the Layout View) and the
physical coordinate system (as generated by the used traversing gear), which
may comprise up to six traversing axes.
When an external traverse file is used, the advanced traverse add-on works
with two coordinate systems:
X, Y, Z logical measuring position coordinates
A, B, C, D, E, F traverse position coordinates
The mesh of logical measuring positions can be generated with the Layout
View Mesh Wizard. The logican traverse mesh may comprise one or more
regions.
The physical traverse position coordinates are located in a look-up table (the
external traverse file) in ASCII format. Each coordinate is placed in a
column each separated by Tab, Comma or Space. The reference between the
logical traverse mesh and the external traverse file is given by the traverse
position index, i.e. the traverse position index in the layout view table
corresponds to the line number in the external traverse file. As an example
the coordinates of a five axis system are given below:
A B C D E
1000 2500 0 -1000 20000
1000 3000 1000 -1100 20000
1000 3500 2000 -1200 20000
1000 4000 3000 -1300 30000
Table 6.5-4: An example for a five-axis external traverse file.
Please note that the coordinate values must be entered in micrometers (µm)
and that the external traverse file shall only contain the position coordinates,
i.e. the first line in the above example (A B C D E) shall not be in the
file.
