At the Kielce University of Technology, a new method of waviness measurement of cylindrical surfaces has been developed. The article deals with the research conducted to find the optimal V-block method parameters that can be used in a measuring device applied to waviness measurement of cylindrical surfaces. In order to keep high measuring accuracy of V-block method, all detectability coefficients which are function of V-block method parameters should not be negative. For this purpose computations were carried out in order to find such angular parameters that can be easily applied in measuring device and allow for obtaining positive detectability coefficients. Results of the study presented in this paper make it possible to modify the design of the measuring device. According to the authors, it will result in increasing the accuracy of V-block waviness measurement of cylindrical parts.

The paper relates to the problem of adaptation of V-block methods to waviness measurements of cylindrical surfaces. It presents the fundamentals of V-block methods and the principle of their application. The V-block methods can be successfully used to measure the roundness and waviness deviations of large cylinders used in paper industry, shipping industry, or in metallurgy. The concept of adaptation of the V-block method to waviness measurements of cylindrical surfaces was verified using computer simulations and experimental work. The computer simulation was carried out in order to check whether the proposed mathematical model and V-block method parameters are correct. Based on the simulation results, a model of measuring device ROL-2 for V-block waviness measurements was developed. Next, experimental research was carried out consisting in evaluation of waviness deviation, initially using a standard non-reference measuring device, and then using the tested device based on the V-block method. Finally, accuracy of the V-block experimental method was calculated.

In many branches of industry there are large and heavy cylindrical elements. The most popular methods applied to measure roundness and waviness of cylindrical parts are radial method. This method can be used mainly for objects with small dimension and lower weight. Radial method is useless for large-size cylinders. For this reason researchers developed V-block method knows as references method to measure roundness of large cylindrical surfaces. At the Kielce University of Technology research is carried out to extend applicability of the V-block method to waviness measurements of large cylindrical mechanical parts. The paper presents fundaments of V-block method and mathematical model. The four types of three-points references method was characterized. In order to determine the most appropriate type of three-point method to waviness measurements the computer simulation was carried out. The simulation was performed in range 16-50 UPR (undulation per revolution) which correspond to surface waviness.
