2.2. Second stage
In the second stage if the user modify the DateIntrare.txt
file saving the
modification of the input parameters, the CATIA software detect this and
warning
by an Update message.
After this message the user have to update the assembly file and the
kinematics file in order to remake
the kinematics couples which may be
modified.
3. Method Quality Verification
It is proposed in following the verification of this method
by comparing the
numerical results obtained with graphical method
regarding the results obtained
by one of the analytical methods: Gohman method; “normals” method;
“minimum distance” method etc [3].
For the polygonal shaft is defined the analytical form of the profile to be
generated, see figure 4:

X = 0;
Σ Y = u;
