CHAPTER ELEVEN MEASURING
11.1 Skip Function
Brief Linear interpolation can be commanded by specifying axial move following the G31, like G01.
If an external signal is input during the execution of this command, execution of the command
is interrupted and the next block is executed.
The skip function is used when the end of measuring is not programmed but specified with
a signal from the machine, for example, in 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 in a custom macro
because they are stored in the custom macro system variable #5016
～
#5019, as follows:
#5016 X axis position of EOB
#5017 Y axis position of EOB
#5018 Z axis position of EOB
#5019 4
th
axis position of EOB
Signal Special signal
SKIPP <G001#1>
[Type] Signal input
[Function] This signal completes the skip cutting. Namely, the position of skip signal
turns into “1” in the block including the G31, which is stored in the user
macro variable, simultaneously, the move code of the block is ended.
[Operation] The controllable equipments are shown in the following when the skip signal
turns into “1”:
z
When the block consists of the skip machining code G31, the current position
of the code axis when the control equipment is read and stored the signal that
it is set to 1. The control equipment stops the move of the axis, and then, clear
the remaindering move distance of this block code axis.
z
The state of the skip signal is monitored instead of its rising edge. In this case,
if the skip signal is still “1”, it is regarded as the skip condition is met
immediately when next skip cutting is commanded.
