4. INTERPOLATION FUNCTIONS
Linear interpolation can be commanded by specifying axial move
following the G33 command, like G01. If an external skip 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 machining 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.
G33 _ ;
G33: One–shot G code (If is effective only in the block in
which it is specified)
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 #5061 and #5062, as follows:
#5061 X axis coordinate value
#5062 Y axis coordinate value
Disable feedrate override, dry run, and automatic
acceleration/deceleration (with parameter No. 6200 and
subsequent parameters) when the feedrate per minute is
specified, allowing for an error in the position of the tool
when a skip signal is input.
If G33 command is issued while cutter compensation C is
applied, an P/S alarm of No.035 is displayed. Cancel the
cutter compensation with the G40 command before the G33
command is specified.
