The Emco 120P I am using is a back tool lathe. Tool turret is above to the right of the spindle, and +X is up, -X is down towards spindle.
For my threading tool which is pointing straight down, if I enter a value into the DIAM column in the Tool Table for the radius of the tool tip, will that then be taken into account as the difference between the physical tip and control point? Or is the control point only considered when using G41/G42? G41/G42 don’t really make sense for this tool since it is pointing down, there isn’t really a left or right for compensation, correct? My threading routine sets G43 (when changing to the tool), but also turns off compensation (G40). Is that what I should be doing? Also, according to the lathe tool orientation diagram here (http://linuxcnc.org/docs/html/lathe/lathe-user.html#lathe-tool-orientation) my threading tool (T3) which is pointing down would be at Position 6 90° (because my +X is pointing up so the diagram needs to be flipped over). If that is correct, I would then enter “6” into the Tool Table Orientation and Back angle = 120 and Front Angle= 60, yes? It is my understanding that these values only affect the display in Axis, yes? -Tom ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
