4. INTERPOLATION FUNCTIONS
In the absolute command, coordinate value of the end point is
In the incremental command the distance the nozzle moves is
_: For an absolute command, the coordinates of an end
position, and for an incremental commnad, the distance
the nozzle moves.
Either of the following nozzle paths can be selected according to bit 1
(LRP) of parameter No. 1401.
D Nonlinear interpolation positioning
The nozzle is positioned with the rapid traverse rate for each axis
separately. The nozzle path is not normally straight.
D Linear interpolation positioning
The nozzle moves along a line to the specified position. The nozzle
is positioned within the shortest possible time at a speed that is not
more than the rapid traverse rate for each axis. However, the
nozzle path is not the same as in linear interpolation (G01).
Non linear interpolation positioning
Linear interpolation positioning
The rapid traverse rate in G00 command is set to the parameter No. 1420
for each axis independently by the machine tool builder. In the
posiitoning 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 ” means that the feed motor is within the specified range.
This range is determined by the machine tool builder by setting to
parameter (No. 1826).
In–position check for each block can be disabled by setting bit 5 (NCI)
of parameter No.1601 accordingly.
