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.
