Abstract: At the Kielce University of Technology a novel method for in situ cylindricity measurement has been developed. It has been called a V-block method and its fundamental is using a set of two connected V-blocks. Along the element connecting V-blocks the measuring sensor moves. The method is characterized by so-called detectability coefficient that is responsible for detection of the harmonic components in observed profile. The value of the coefficient depends on the angular method parameters, i.e. V-blocks angle and the position of the sensor. The paper presents fundamentals of the V-block method and results of the research work on influence angular method parameters on measurement results.
