When G00X_Y_T ; is specified in a machine having a turret axis (T–axis),
the X and Y axes move to the specified positions at rapid traverse rate and
also the T–axis moves at the predetermined rapid traverse rate in such a
way as to select a specified tool number.
In a machine provided with a die angle index (C–axis), if “G00X_Y_ ; ”
is specified, the X, Y, and C axes move simultaneously at the
predetermined rapid traverse rate.
Refer to “C axis control” for the details. Since this control system treats
the turret punch press as a controlled system, the tool moves to the
commanded position as fast as possible for punching as the basic
principle.
Accordingly, the tool is positioned at rapid traverse, punching is done
after axis movement in the G00 mode, in principle.
Refer to “Punch function” for details.
The rapid traverse rate in the G00 command is set for each axis
independently by the machine tool builder (parameter No. 1420).
Accordingly, the rapid traverse rate cannot be specified in the address F.
In the positioning mode actuated by G00, the tool is accelerated to a
predetermined speed at the start of a block and is decelerated at the end
of a block. Execution proceeds to the next block after confirming the
in–position.
“In–position” means that the feed motor is within the specified range.
(This range is determined by the machine tool builder) (Parameter No.
1827)
CAUTION
For T– or C–axis command blocks, nonlinear interpolation
positioning is performed, even if linear interpolation
positioning is specified.
And, for block including G28 or G53 command, nonlinear
interpolation positioning is performed.
