Modified functions 34059x-06
When editing the tool table or tool management, only the
current table line is blocked, see "Editing the tool table",
page 248
When importing tool tables, nonexistent tool types are imported
as type undefined, see "Importing tool tables", page 252
You cannot delete the tool data of tools still stored in the pocket
table, see "Editing the tool table", page 248
In all manual probing functions, quicker selection of the start
angle of holes and studs is possible with soft keys (paraxial
probing directions), see "Functions in touch probe cycles",
page 752
When probing, after acceptance of the actual value of the 1st
point for the 2nd point the soft key for the axis direction is
shown
In all manual probing functions, the direction of the reference
axis is suggested as a default
In manual probing cycles the hard keys
END
and
Adopt Actual Position
may be used
The display of the machining feed rate has been changed
in manual mode, see "Spindle speed S, feed rate F and
miscellaneous function M", page 732
In the file management, the programs or directories at the
cursor position are also displayed in a separate field beneath the
current path display
Block editing no longer causes block marking to be canceled. If
a block is edited with active block marking and another block is
then selected via the syntax search, the marking is expanded
to the newly selected block, see "Marking, copying, cutting and
inserting program sections", page 172
In the screen layout
P SECTS
it is possible to edit
the structure in the structure window, see "Definition and
applications", page 212
The functions
APPR CT
and
DEP CT
allow approach to and
departure from a helix. This movement is carried out as a helix
with an even pitch, see "Overview: Types of paths for contour
approach and departure", page 290
The functions
APPR LT
,
APPR LCT
,
DEP LT
and
DEP LCT
position all three axes at on the auxiliary point at the same time,
see "Approaching on a straight line with tangential connection:
APPR LT", page 293, see "Approaching on a circular path with
tangential connection from a straight line to the contour: APPR
LCT", page 295
The values entered for the traverse limits are checked for
validity, see "Entering traverse limits", page 850
When calculating the axis angle in the axes chosen with M138,
the control sets the value to 0, see "Selecting tilting axes:
M138", page 623
The input range in columns SPA, SPB and SPC of the preset
table was expanded to 999.9999, see "Managing presets",
page 739
Tilting is permitted in combination with mirroring, see
"The PLANE function: Tilting the working plane (option 8)",
page 587
