Function
Note
The "Measure kinematics" function is an option and is available from measuring cycles
SW 7.5 onwards!
With the "Measure kinematics" function, it is possible to calculate the geometric vectors used
to define the 5-axis transformation (TRAORI and TCARR) by measuring the position of the
ball in space.
The measurement is essentially carried out by means of workpiece probes, which scan three
positions of a measuring ball on each rotary axis. The ball positions can be defined in
accordance with user specifications so that they correspond to the geometric ratios on the
machine. The only way of setting the ball positions is to reposition the rotary axis that is to be
measured in each case.
Aside from the basic mechanics of the machine, no specific knowledge is required to use
CYCLE996. No dimension drawings or machine location diagrams are necessary to carry
out measuring.

Application range
The "Measure kinematics" function (CYCLE996) can be used to determine the data that is
relevant to transformations in the case of kinematic transformations that involve rotary axes
(TRAORI, TCARR).
Options:
● Redetermination of swivel data records
– Machine startup
– Use of swivel-mounted workholders as TCARR
● Checking swivel data records
– Service following collisions
– Checking the kinematics during the machining process
Kinematics with manual axes (manually adjustable rotary tables, swivel-mounted
workholders) can be measured in the same way as kinematics with NC-controlled rotary
axes.
When CYCLE996 is started, a swivel data record with basic data (for kinematics type, see
Programming Manual Cycles CYCLE800) must be parameterized.The measurement itself must be carried out without an active kinematic transformation.

Requirements
The following requirements must be met in order to use CYCLE996 (Measure kinematics):
● SIEMENS measuring cycles package is installed
● Workpiece probe is calibrated
● Calibration ball is mounted
● Oriented tool carrier is initialized (MD 18088: MM_NUM_TOOL_CARRIER > 0)
● The basic geometry of the machine (X, Y, Z) is rectangular and referenced
The right angle refers to the workpiece spindle and should be preferably checked using a
test mandrel.
● Defined position of the rotary axes involved in the transformation
● Defined traverse directions in compliance with the standard of all axes involved in the
transformation according to ISO 841-2001 and/or DIN 66217 (righthand rule)
