Workpiece Coordinate System Setting And Offset ; G54 To G59 (G54.1) - Mitsubishi Electric MELDAS C6 Programming Manual

14. Coordinates System Setting Functions

14.10 Workpiece coordinate system setting and offset ; G54 to G59 (G54.1)

Function and purpose
(1) The workpiece coordinate systems are for facilitating the programming of workpiece
machining in which the reference point of the workpiece to be machined is to serve as the zero
point.
(2) These commands enable the tool to move to the positions in the workpiece coordinate system.
There are 6 workpiece coordinate systems which are used by the programmer for
programming. (G54 to G59)
In addition to the six sets of workpiece coordinate systems between G54 and G59, there are
48 additional workpiece coordinate system sets. (The 48 sets are options.)
(3) Among the workpiece coordinate systems currently selected by these commands, any
workpiece coordinate system with coordinates which have been commanded by the present
position of the tool is reset. (The "present position of the tool" includes the offset amounts for
tool radius, tool length and tool position offset.)
(4) An imaginary machine coordinate system with coordinates which have been commanded by
the present position of the tool is set by this command.
(The "present position of the tool" includes the offset amounts for tool diameter, tool length and
tool position offset.) (G54, G92)
