Measurement
General Linear interpolation can be commanded by specifying axial following the G31 instruction,
like G01. If an external skip signal is input during the execution of this instruction,
execution of the instruction is halted and the next block is executed.
The skip function is used when the end of machining is not programmed but specified with
a signal from the machine, for example, during grinding. It is used also for measuring the
dimensions of a workpiece.
The coordinate values when the skip signal is turned on can be used during a custom
macro because they are stored during the custom macro system variable #5016
～
#5019,
as follows:
#5016 X-axis block’ end point position
#5017 Y-axis block’ end point position
#5018 Z-axis block’ end point position
#5019 4TH-axis block’ end point position
Signal Skip signal
SKIP （ G001#1 ）
[Classification] Input signal
[Function] This signal terminates skip cutting. That is, the position where a skip signal
turns to “1” during a block containing G31 is stored during a custom macro
variable, and the move instruction of the block is terminated at the same
time.
[Operation] When a skip signal turns to “1”, the control unit works as described below.
z
When a block contains a skip cutting instruction G31, the control unit reads and
stores the current position of the specified axis at that time. The control unit stops
the axis, then cancels the remaining distance that the block was supposed to be
moved.
z
The skip signal is monitored not for a rising edge, but for its state. So, if a skip
signal continues to be “1”, a skip condition is assumed to be satisfied immediately
when the next skip cutting is specified.
Note: The skip signal width requires at least 10ms.
