5 Chapter 6: NC Programming Coordínate Systems Coordínate systems allow the posítions of a work-píece to be logícally transferred frem a biueprint or drawing to a location on a machine tool. The following figure describes the axis directions on a Vertical milling machine. The arrow direction specifies the actual movement direction of the work table. The small coordínate frame on the rights shows the relative cutter movement direction. Again, coordínate systems are used to describe the path and tocí position relative to the work-piece and machine. There are three levéis coordinates in the 4M CNC system: machine coordinates, work offset coordinates, and locai coordinates. Machine coordinates The machine coordínate system has a fixed position which s determined inherently by the design of the machine. Some positions such as the tool change position, limit swítch posítions etc. can not be altered. The machine coordínate system is known as the G53 coordínate system or also referred to as machine zero or home reference point. The máximum allowed movement range of the spindle and the rectangular región in X Y Z direction is, respectively, the valid travel of each axis according to the G53. 83
