It depends on whether the machine moves the tool or the part, or both. Z will always be along the tool spindle, and increasing Z increases the distance between the tool and the work, regardless of which moves. You then set up a right-hand coordinate system (Thumb-X, index finger Y, middle finger Z) with the finger in question showing the direction that the tool moves relative to the work (regardless of which is actually moving) for increasing numerical value. My little knee-mill is an interesting sample case. It is a fixed-spindle machine so in vertical milling mode X+ moves the table to the left, Y+ moves the table away from the column, Z+ moves the table down the column. However, I also have a horizontal spindle, and in that config, and standing in the same place X+ now move the table to the right (which is to the left looking down the axis of the tool from the back of the machine). Y+ moves the table down the column, and Z+ moves the table away from the column. I did have the option of reversing the Y instead of the X, and that would still have worked but might have been even more confusing. It does matter, if you set the axes up wrongly then you will get mirror parts. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
