you run into this on swiss type turning centers quite a bit the controll knows those two are parallel and opposed so you give a code to lock the motion together ,or it might be coordinated motion with a floating zero anyway they split the feed between them ,so they'd each move at 4 to get the 8 you wanted it gets even more confusing when you have a turning tool in the cut at the same time Z1 is feeding at the turning tools feedrate while Z2 is making up the difference ,it could even be backing up if the turning tools feed is higher ,it looks really odd to peck drill that way Brian ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
