I assume this means that X is along the original linear X axis, Y is along the original linear Y axis and Z is perpendicular to X and Y.

One interpretation is: U is in a direction that is on the same plane as the tool axis and the original X axis and is in a direction perpendicular to the tool axis. V is in a direction that is on the same plane as the tool axis and the original Y axis in a direction perpendicular to the tool axis. The W would be parallel to the tool axis. Is that what you mean? It makes sense that it would be useful to have a "tool centric" set of axis. The difficulty is that there are an infinite number of them. What I've described, above, is one that seems to make some sort of sense. > This same treatment could be used for rotating/adjusting the > program to the part. > > Comments, Considerations, Criticism > thanks > Stuart > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move Developer's challenge > Build the coolest Linux based applications with Moblin SDK & win great prizes > Grand prize is a trip for two to an Open Source event anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > Emc-developers mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-developers Ken ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
