Chucking equipment in simulation G65
G65 displays the selected chucking equipment in the simulation
graphics.
Workpiece blank contour G67 (for graphics)
G67 displays an auxiliary workpiece blank in the simulation graphics.
Period of dwell G4
With G4, the control interrupts the program run for the time F before
executing the next program block. If G4 is programmed together with
a path of traverse in the same block, the dwell time only becomes
effective after the path of traverse has been executed.
Precision stop G7
G7 switches precision stop on. It is a modal function. With a precision
stop, the control does not run the following block until the last point
has been reached in the tolerance window for position. The tolerance
window is a configuration parameter ("ParameterSets PX(PZ)/
CfgControllerTol/posTolerance").
Precision stop affects single contours and cycles. The NC block
containing G7 is also executed with a precision stop.
