INA calculation program
In order to depict the working cycle of the machine, a duty cycle must
be described. This is composed of the motion parameters of the
machine and their loading due to external loads (e.g. machining
forces).
On the basis of a speed/time diagram, the working cycle should be
subdivided logically into individual load cases, Figure 9, to .
With the aid of the basic motion formulae for uniform motion
(v = const.) or uniform acceleration (a = const.) as appropriate,
the missing values (travel, acceleration) can then be determined.
