    Abstract

    Depending on the maintenance strategy there can be enormous differences how much energy the machinery uses and how much waist it produces. It has become a common practise to study the efficiency of production machinery together with the quality of production and availability of this machinery i.e. the overall effectiveness is studied. In order to reach high efficiency, high availability and good quality, the production machinery has to be in the condition to fulfil these goals. In principle there are two questions that need to be answered when maintenance is planned for tackling the above described situation: 1) What do we have to do? 2) When do we need to take action? The maintenance strategy that has been developed to answer these questions in an optimal way is Condition Based Maintenance (CBM) i.e. the maintenance actions are based on the need of the machinery. Up to this level everything is very logical and clear but unfortunately the current reality in the industry is far from optimal. It is not an easy task to define the condition of production machinery and it is not easy to say what needs to be done and when. This paper is oriented to help to answer the What question i.e. diagnosis of the condition of machinery and When question i.e. prognosis of wear development is not discussed in detail. However, the What question as such is already very demanding. The reason for this is that automatic diagnosis should be based on measurements of the condition and this becomes very difficult in practise due to the differences in the production machinery and the difficulty in separating the condition information from information that is related to the production parameters.
