Functions changed since the predecessor
versions 340420-xx and 340 421-xx
„ The datum shift in datum table function was changed. REF-based
datums are no longer available. Instead, the preset table was
introduced (see “DATUM SHIFT with datum tables (Cycle 7)” on
page 431)
„ The function of Cycle 247 was changed. Cycle 247 now activates a
preset from the preset table (see “DATUM SETTING (Cycle 247)”
on page 435)
„ Machine parameter 7475 is now meaningless (see “Compatibility
machine parameters for datum tables” on page 623)
„ The old fixed cycles 1, 2, 3, 4, 5, 17 and 18 were removed from he
soft-key structure and can therefore no longer be defined. Old
programs containing these cycles can still be run, however.
„ The Show blank in work space function was revised (see
“Showing the Workpiece in the Working Space” on page 596)
„ Automatic tool change after expiration of the tool life (M101) now
goes faster (see “Automatic tool change if the tool life expires:
M101” on page 166)
„ M116 now ignores swivel-head rotary axes (see “Feed rate in mm/
min on rotary axes A, B, C: M116 (software option 1)” on page 257)
„ In Cycles 251 to 254 the plunging behavior was changed. In vertical
plunging (Q366=0). the plunging angle ANGLE in the tool table must
now be set to =90°. Up to now, ANGLE had to be set to 0° for
vertical plunging. (see “Cycles for Milling Pockets, Studs and Slots”
on page 327)
„ In Cycles 251 to 254 the behavior for the finishing machining
operation (Q215=2) and oversize=0 (Q368/Q369) was changed.
(see “Cycles for Milling Pockets, Studs and Slots” on page 327)
„ The maximum number of tools in the tool table was reduced to
30 000 (see “Entering tool data in tables” on page 154)
„ The tool usage monitor was expanded by the capability of running
for a complete pallet (see “Dependent files” on page 593)
