“…From equation ( 8), searching the center o Ci of MCC, the center o Ii of MIC and the center o Zi of MZC of the ith roundness profile is actually an optimization issue. Some researchers have studied many optimization algorithms [12][13][14] for three corresponding evaluation criteria of the roundness.…”

Measurement principle of axis straightness error of cylindrical parts was introduced based on their roundness profiles. The evaluation models of the center coordinates of four kinds of the reference circles were built, and the evaluation models of the axis straightness errors were established by using the least-square and minimum zone criteria. The roundness profiles of eight simulated cylinders, eight holes, and eight shafts were extracted, and their axis straightness errors were evaluated based on the different reference circles and evaluation criteria. The “minimax” issues in the evaluation process of axis straightness errors were be solved by using Equilibrium Optimizer, and its implementation flows were given. Their evaluation results were analyzed under the used reference circles and evaluation criteria. The analysis results showed that both reference circles and evaluation criteria have much influence on the evaluation results, and that among the evaluation results based on the centers’ coordinates of four reference circles and two evaluation criteria, the axis straightness errors evaluated based on the center coordinates of least-square reference circle and the minimum zone criteria is the least one for most of cylindrical parts, the roundness profiles of which may have no singularities, and the differences among the axis straightness errors evaluated on the basis of different reference circles and different evaluation criteria are very large sometimes, which should be noted in checking whether the axis straightness errors of parts are qualified.

“…The most commonly used methods for roundness error evaluation are the least-squares method (LSM), the minimum zone circle (MZC) method, the maximum inscribed circle (MIC) method and the minimum circumscribed circle (MCC) method [34]. In this paper, LSM and MZC are used to calculate the roundness error at the same time.…”

The crankshaft is the core part of an automobile engine, and the accuracy requirements of various shape and position errors are very high. On the basis of a synchronous measurement system, the connecting rod journal is deeply studied, including data processing and roundness evaluation. Firstly, according to the measuring processes of connecting rod journals, the real sampling angle distribution function was established, and the corresponding Gaussian weight function of each sampling angle was calculated. The weight function and the collected data corresponding to the angle were subjected to discrete cyclic convolution operation in the spatial domain to obtain the filtered effective circular contour data. Secondly, the particle swarm optimization algorithm was improved, and its inertia weight was set to decrease nonlinearly to speed up the convergence. A calculation process suitable for the evaluation of journal errors was designed. Then, the improved particle swarm optimization algorithm was used to evaluate the roundness of the corrected rod journal contour data. At last, through multiple measurement experiments, the feasibility and effectiveness of the synchronous measurement scheme and data processing method proposed in this paper are verified.

“…Three global sizes above correspond to minimum circumscribed method, maximum inscribed method and minimum zone method in the evaluation of cylindricity errors, respectively. There have been many optimization algorithms used for the evaluation of cylindricity errors by many researchers, such as, genetic algorithm [6], geometry optimization searching algorithm [7], kinematic geometry optimization algorithm [8] and so on [9,10]. These optimization algorithms can also be used for the evaluation of the global sizes.…”

The measurement method of the global sizes of cylindrical parts based on Talyrond 585LT and the standard ring was proposed. The changing processes from the roundness profiles measured by Talyrond 585LT to the actual roundness profiles was studied for holes and shafts, respectively. The evaluation models of the least-squares diameter, minimum circumscribed diameter, maximum inscribed diameter and minimax diameter of cylindrical parts were given. The roundness profiles of two holes and two shafts were extracted and changed into their corresponding actual roundness profiles. Their global sizes were evaluated, and their measurement uncertainties were analyzed and estimated. The analysis and experiment results showed that the above measuring method can meet the measurement need of the global sizes of cylindrical parts for implementation of ISO 14405-1 in the manufacturing industry.
