Note on markers _M2 to _M13
When the swivel data set or tool is changed, the linear axes are recovered using the last
retraction mode (modal).
If this behavior is not desired in milling/turning, the corresponding calls must be commented
out with a semicolon (;). The E_SWIV_H or F_SWIV_H cycle is called in milling/turning (see
markers _M2 to _M9) in the CUST_800.SPF manufacturer cycle.
Parameter E_SWIV_H (Par1, Par2, Par3)
● Par1: Number of swivel data set (_TC1)
● Par2: Angle of 1st rotary axis
● Par3: Angle of 2nd rotary axis
Modification examples
If the rotary axes (swivel head/table) are not to be positioned during swivel data change / tool
change, the call of the E_SWIV_H cycle can be commented out at the relevant markers. If
the rotary axes are to move to a certain position, an angle value can be transferred to
parameters Par 2, Par 3.
Note on markers _M14, _M15
Depending on the values of the retraction plane and the programmed swivel plane, it is
possible that the linear axes now also travel the swiveled retraction plane while running up
from the current position to the software limit switches after a block search. To avoid this
problem, marker _M14 in the CUST_800.SPF is called after swiveling. The E_SP_RP(30)
cycle preset there runs up to the milling retraction plane, whereby travel may be along the
software limit switches. An appropriate retraction after block search can be set at marker
_M15.
Note on the marker _M16
If for a swivel data set change or when de-selecting the swivel data set, you wish to traverse
the rotary axes to zero, the syntax of the _M16 marker can be modified accordingly, e.g.
activate block N8006 E_SWIV_H(_TC1,0,0).
Note on markers _M20 to _M31
Markers _M20 to _M31 are distinguished by machine kinematics with two rotary axes or one
rotary axis. A distinction is also made between automatic rotary axes (known to the NCU)
and manual (semi-automatic) rotary axes. There is only ever one valid marker for swiveling
with the active swivel data set.
Note on marker _M35
Run through _M35 for block search and a swivel data set with manual rotary axes.
