3.5.6 Inspection Mode
This function interrupts the program sequence,
checks and corrects the ”active tool,” inserts a new
cutting edge and continues the NC program from the
point of interruption.
The inspection cycle is executed as follows::
Interrupt the program sequence and retract the
tool.Check the tool, and replace the cutting edge if
necessary.n Return the tool.
■ Cutting edge OK: Continue the automatic
program run.
■ New cutting edge: Define the compensation
values by ”scratching,” and continue the automatic
program run.
When the tool is retracted, the CNC PILOT stores the
first five traverse movements. Each change in
direction corresponds to a path of traverse.
The NC program run can be continued before the
point of interruption. Specify the distance to the
interruption point. If the value is greater than the
distance between the start of the NC block and the
interruption point, program sequence begins at the
start of the interrupted NC block.
■ During the inspection process you can
turn the turret, press the spindle keys, etc.
■ If the turret was turned, the return
motion program inserts the ”correct” tool.
■ When changing the cutting edge, select
the compensation values so that the tool
stops in front of the workpiece.
■ In the cycle stop condition you can
interrupt the inspection cycle with ESC and
switch to ”Manual control.”
