Abstract:

In many industries ( for example, in paper, electric or ship industry), large and heavy cylindrical elements play very important role. Such workpieces should posses very good quality of form and dimensions. Sometimes, they may be deformed under certain operating conditions, e. g. due to a high temperature or great external or internal loads. Consequently, wear and damage of the working surfaces are observed. Therefore cylindricity deviations of such workpieces should be measured during their manufacturing and exploitation. However, some of the workpieces cannot be measured accurately by existing measuring instruments because they are too large or too heavy and therefore they cannot be placed on the measuring table of the instrument. This is why the industries manufacturing or applying cylinders expect that measurements of cylindricity profiles will be made directly on the machine tool or in the work area. In the paper methods allowing such measurements are investigated. The methods are divided into two main groups: multisensor and V-block methods. Most important advantages and disadvantages of both groups of methods allowing accurate in situ cylindricity measurements are given as conclusions.
