Additional settings
For the swivel function, set the following machine data as a minimum to the following - although
this deviates from the default value:
MD10602 $MN_FRAME_GEOAX_CHANGE_MODE
= 1 The actual total frame (zero offsets) is recalculated when switching over geometry axes
(selecting/deselecting TRAORI).
MD10760 $MN_G53_TOOLCORR Method of operation with G53, G153 and
SUPA
Bit 0 = 1 If the machine axis/axes are to be retracted before swiveling, see Chapter "Manufacturer
cycle CUST_800.SPF (Page 589)"
MD11450 $MN_SEARCH_RUN_MODE Settings, block search
Bit 1 = 1 Activate PROG_EVENT.SPF after block search. This means that for a block search, the
rotary axes of the active swivel data set are pre-positioned.
Declare swivel data sets
For the swivel function, swivel data sets must be created in the NCK and declared in the
following machine data.
MD18088 $MN_MM_NUM_TOOL_CARRIER Maximum number of definable tool holders
that can be oriented.
Number of swivel data sets
If several channels are declared in the NCU, the number of swivel data sets is split up, taking
MD28085 $MN_MM_LINK_TOA_UNIT into account.
Example 1:
Machine has two channels with different TO units.
Channel 1: MD28085 $MN_MM_LINK_TOA_UNIT= 1
Channel 2: MD28085 $MN_MM_LINK_TOA_UNIT= 2
Three swivel data sets (SDS) are required for each TO unit.
MD18088 = (number of TO units) x (number of SDS per TO unit) = 2 x 3 = 6
Example 2:
Machine has three channels with two different TO units.
Channel 1: MD28085 $MN_MM_LINK_TOA_UNIT= 1
Channel 2: MD28085 $MN_MM_LINK_TOA_UNIT= 2
Channel 3: MD28085 $MN_MM_LINK_TOA_UNIT= 1
One swivel data set (SDS) is required for each TO unit.
MD18088 = (number of TO units) x (number of SDS per TO unit) = 2 x 1 = 2
