Industrial robotics represents a key technology for
flexible and reconfigurable manufacturing systems and is
widely adopt to perform several industrial tasks e.g.
material handling, welding, assembly, spray painting or
glazing, and machine tending [1].
However, just 3%÷4% of the overall number of
industrial robots is employed for mechanical machining
[2]. Such field of application is traditionally covered by
very expensive and rigid systems as machining centers.
With respect to such manufacturing technologies,
industrial robots provide superior dexterity, higher
flexibility and reconfigurability and better cost
effectiveness but still lack in absolute accuracy and
mechanical stiffness [3], [4].
