14.10 Workpiece Coordinate System Setting and Offset ; G54 to G59 (G54.1)
Function and purpose
(1) The workpiece coordinate systems facilitate the programming on the workpiece, serving the
reference position of the machining workpiece 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 or 96 additional workpiece coordinate system sets. (The 48 sets and 96 sets are optional
specifications.)
(3) By these commands, the workpiece coordinate system will be re-set so that the present
position of the tool on the current workpiece coordinate system become the commanded
coordinates. (The "present position of the tool" includes the compensation amounts for tool
radius, tool length and tool position.)
(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 compensation amounts for tool diameter, tool
length and tool position compensation.) (G54, G92)
