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 1st rotary axis
● Par3: Angle 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 labels _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, label
_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 label _M15.
Note on the label _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 label can be modified accordingly, e.g. activate
block N8006 E_SWIV_H(_TC1,0,0).
Note on labels _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 label for swiveling with the
active swivel data set.
Note on label _M35
Run through _M35 for block search and a swivel data set with manual rotary axes.
