It doesn't sound right > does it what should I do? My take on this: Conventionally the spindle moves in the Z axis. This is the case for both lathes and mills. The normal rotary axes are A which has an axis parallel to X, B parallel to Y and C parallel to Z. Then U V and W are extra linear axes parallel to X,Y,Z. So, in your picture you have an XZCW machine (assuming that the tool spindle does not move up and down, which would be Y) and you are thinking of adding a B axis (which pivots around Y) Then I think your GEOMETRY= would be CXZBW (but I might be wrong) -- atp ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
