5.10 CYCLE996 workpiece: Measure kinematics
Basic kinematics data
The functionality of CYCLE996 requires the NCK function "Tool carrier with orientation
capability (TCARR)" (see also Programming Manual Cycles CYCLE800).
The number of tool carriers with orientation capability must be entered in machine data MD
18088: MM_NUM_TOOL_CARRIER.
If the dynamic 5-axis transformation (TRAORI) is also to be set (or is the only function to be
set), MD 24x00 $MC_TRAFO_TYPE_x = 72 (x = 1...8) should ideally be set, as should the
number of the TOOLCARR swivel data record to be used in MD 24582
TRAFO5_TCARR_NO_1.
The following basic kinematics data must be known at the start of CYCLE996:
It is entered in either the "Swivel cycle" startup menu (CYCLE800) or in the screen form for
the 1st measurement (SK swivel data record).
● Kinematics type: Swivel head ("T"), swivel table ("P") or mixed kinematics ("M")
● Name of swivel data record
● Approximate rotary axis vector V1xyz of rotary axis 1 (e.g, axis B swivels around Y V1 =
● Approximate rotary axis vector V2xyz of rotary axis 2 (if this exists) (e.g, axis C swivels
● Name of rotary axes
● Mode of rotary axes: automatic (NC rotary axes), manual or semi-automatic
● Travel range of rotary axes
