General

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
● Checking swivel data records
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.
