CYCLE996 measure workpiece kinematics

Function
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).
