6. Interpolation Functions
(Note 2) When parameter "#1086 G0Intp" is set to 1, the tool will move along the path from the
start point to the end point at the rapid traverse rate of each axis.
When, for instance, the Y-axis and Z-axis rapid traverse rates are both 9600mm/min, the
tool will follow the path in the figure below if the following is programmed:
G91 G00 X-300000 Y200000 ; (With an input setting unit of 0.001mm
(Note 3) The rapid traverse rate for each axis with the G00 command differs according to the
individual machine and so reference should be made to the machine specifications
manual.
(Note 4) Rapid traverse (G00) deceleration check
There are two methods for the deceleration check at rapid traverse; commanded
deceleration method and in-position check method. Select a method with the parameter
"#1193 inpos".
■ When "inpos" = "1"
Upon completion of the rapid traverse (G00), the next block will be executed after
confirming that the remaining distances for each axis are below the fixed amounts.
(Refer to the following drawing.)
The confirmation of the remaining distance should be done with the imposition width,
L . L
R
The purpose of checking the rapid traverse deceleration is to minimize the time it takes
for positioning. The bigger the setting value for the servo parameter "#2224 SV024",
the longer the reduced time is, but the remaining distance of the previous block at the
starting time of the next block also becomes larger, and this could become an obstacle
in the actual processing work. The check for the remaining distance is done at set
intervals. Accordingly, it may not be possible to get the actual amount of time reduction
for positioning with the setting value SV024.
