Alarm Description
Cause The figure data is incorrect in bar machining. This alarm is
raised when the relationship between start point coordinate
and figures is incorrect.
Action On the figure data window for the process corresponding to
this alarm, check the machining figure. If the figure is
incorrect, enter correct figure data.

Reference III.1 Bar Machining (Roughing), III.2 Bar Machining
(Finishing)
Cause A correct tool path cannot be calculated in bar machining.
This alarm is raised when there is an error in the result of
internal calculation (for example, when the value under a
square root sign is negative because of an error in
calculation).
Action On the figure data window for the process corresponding to
this alarm, check the machining figure. If the figure is
incorrect, enter correct figure data. If the figure is correct,
the tool or finishing amount cannot be used for this figure.
Reduce the finishing. Alternatively, use a tool with a smaller
radius at the tool tip.

Reference III.1 Bar Machining (Roughing), III.2 Bar Machining
(Finishing)
Cause The groove width is incorrect in grooving. This alarm is
raised when the width of the tool used is larger than the
groove width.
Action On the process data window for the grooving process
corresponding to this alarm, check the groove width. If the
width is incorrect, enter correct value. Otherwise, select a
tool whose cutting edge width is smaller than the groove
width.
3026
Reference III.4 Grooving (Standard)
Cause Cutting in trapezoidal grooving is impossible because of the
relationship of the groove bottom width and the tool width.
This alarm is raised when the cutting edge width of the tool
used is larger than the groove bottom width in trapezoidal
grooving.
Action Check the figure, on the figure data window for the grooving
process corresponding to this alarm. If the figure is
incorrect, enter correct data. Otherwise, select a tool whose
cutting edge width is smaller than the groove width.
3028
Reference III.5 Grooving (Trapezoidal)
Cause The start point for threading coincides with the end point.
Action On the figure data window for the threading process
corresponding to this alarm, enter correct data for the figure.
3029
Reference III.3 Threading
Cause An invalid chamfering tool is set for C-axis grooving. This
alarm is raised when the small diameter of the chamfering
tool used is larger than the groove width.
Action Use a chamfering tool whose small diameter is smaller than
the groove width.
