Tool Change Position Return ; G30.1 To G30.6 - Mitsubishi Electric MELDAS C6 Programming Manual

13. Program Support Functions

13.11 Tool change position return ; G30.1 to G30.6

Function and purpose
By specifying the tool change position in a parameter "#8206 TOOL CHG. P" and also specifying a
tool change position return command in a machining program, the tool can be changed at the most
appropriate position.
The axes that are going to return to the tool change position and the order in which the axes begin
to return can be changed by commands.
Command format
(1) The format of tool change position return commands is as follows.
G30. n;
n = 1 to 6 : Specify the axes that return to the tool change position and the order in
For the commands and return order, see next table.
(Note 1) An arrow ( → ) indicates the order of axes that begin to return. An period ( • )
(2) The tool change position return on/off for the added axis can be set with parameter "#1092
Tchg_A" for the added axis.
Note, however, that the added axis always return to the tool change position only after the
standard axes complete returning (see the above table).
The added axis alone cannot return to the tool change position.
which they return.
Command
Z axis → X axis • Y axis
G30.1
Z axis → X axis → Y axis
G30.2
Z axis → Y axis → X axis
G30.3
X axis → Y axis • Z axis
G30.4
Y axis → X axis • Z axis
G30.5
X axis • Y axis • Z axis
G30.6
indicates that the axes begin to return simultaneously. (Example : "Z axis → X axis,
Y axis" indicate that the Z axis returns to the tool change position, then the X and Y
axes does.)
