Before there was CNC there was NC. An intermediate stage between hydraulic copying and CNC had machines moving to coordinates stored on paper tape or punched cards. No computers were involved, it was just raw numbers on the cards. An example might be the Hardinge HNC Lathes. Then computers were added that parsed G-code to calculate the positions, and those were a Computer version of NC. So CNC was born. See the Hardinge HCNC for an example of the distinction. Really CAM for "computer aided machining" would be a better acronym, using CAM to mean "converting a model to g-code" is something of a misnomer. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
