Compensation of tool length in the
position display The values L and DL from the tool table
and the value DL from the TOOL CALL are
taken into account in the position display The values L and DL from the tool table
are taken into account in the position
display
Traverse movement in spacial arc Error message is issued No restrictions
SLII Cycles 20 to 24:
„ Number of definable contour
elements „ Max. 16384 blocks in up to 12
subcontours „ Max. 8192 contour elements in up to
12 subcontours, no restrictions for
subcontour
„ Define the working plane „ Tool axis in TOOL CALL block defines
the working plane „ The axes of the first positioning block
in the first subcontour define the
working plane
„ Position at end of SL cycle „ End position = clearance height above
the last position that is defined before
the cycle call „ With MP7420, you can define
whether the end position is above the
last programmed position, or whether
the tool moves only to clearance
height
„ Handling of islands which are not
contained in pockets „ Cannot be defined with complex
contour formula „ Restricted definition in complex
contour formula is possible
„ Set operations for SL cycles with
complex contour formulas „ Real set operation possible „ Only restricted performance of real
set operation possible
„ Radius compensation is active during
CYCL CALL „ Error message is issued „ Radius compensation is canceled,
program is executed
„ Paraxial positioning blocks in contour
subprogram „ Error message is issued „ Program is executed
„ Miscellaneous functions M in contour
subprogram „ Error message is issued „ M functions are ignored
„ M110 (feed-rate reduction for inside
corner) „ Function does not work within SL
cycles „ Function also works within SL cycles
SLII Contour Train Cycle 25: APPR/DEP
blocks in contour definition Not allowed, machining of closed
contours is more coherent APPR /DEP blocks are allowed as contour
elements
General cylinder surface machining:
„ Contour definition „ With X/Y coordinates, independent of
machine type „ Machine-dependent, with existing
rotary axes
„ Offset definition on cylinder surface „ With datum shift in X/Y, independent
of machine type „ Machine-dependent datum shift in
rotary axes
„ Offset definition for basic rotation „ Function available „ Function not available
„ Circle programming with C/CC „ Function available „ Function not available
„ APPR /DEP blocks in contour definition „ Function not available „ Function available
Cylinder surface machining with
Cycle 28:
„ Complete roughing-out of slot „ Function available „ Function not available
„ Definable tolerance „ Function available „ Function available
Cylinder surface machining with
Cycle 29 Direct plunging to contour of ridge Circular approach to contour of ridge
