HEIDENHAIN TNC 640 509
Cycles 25x for pockets, studs and
slots:
„ Plunging movements
In limit ranges (geometrical conditions of
tool/contour) error messages are
triggered if plunging movements lead to
unreasonable/critical behavior In limit ranges (geometrical conditions of
tool/contour), vertical plunging is used if
required
„ Rough out strategy Cycle 251
The lateral infeed with rough out
movements is calculated according to
the ratio of “longer side/shorter side”.
With longer pockets this means a longer
run-time. The lateral proportioning of cuts is
calculated with the maximum
overlapping factor.
PLANE function:
„ TABLE ROT /COORD ROT not defined „ Configured setting is used „ COORD ROT is used
„ Machine is configured for axis angle „ All PLANE functions can be used „ Only PLANE AXIAL is executed
„ Programming an incremental spatial
angle according to PLANE AXIAL „ Error message is issued „ Incremental spatial angle is
interpreted as an absolute value
„ Programming an incremental axis
angle according to PLANE SPATIAL if
the machine is configured for spatial
angle „ Error message is issued „ Incremental axis angle is interpreted
as an absolute value

Compensation of tool length in the
position display The DL value from the TOOL CALL and the
tool length entries L and DL from the tool
table are taken into account in the
position display The tool length entries L and DL from the
tool table are taken into account in the
position display
