7. COORDINATE SYSTEMS
NC FUNCTION
63
A coordinate system in which the zero point is set to a fixed point on the
workpiece, to make programming simple.
A workpiece coordinate system may be set by using one of the following
methods:
(1) Using G92 (G50 for T series with G code system A)
(2) Automatic setting
(3) Using G54 to G59
When (1) is used, a workpiece coordinate system is established using the
numeric value programmed after G92.
When (2) is used, a workpiece coordinate system is automatically
established upon a manual reference position return.
When (3) is used, six workpiece coordinate systems must be set from the
MDI panel in advance. The workpiece coordinate system to be used is
selected by specifying a code selected from G54 to G59.
(G90) G92 _ ;IP
By using the above command, a workpiece coordinate system can be set
so that the current tool position is at a specified position.
