Cylindricity and its measurement

Study on the Form Error Evaluation Model of a Conical-Shank Ball-End Milling Cutter

“…It is noted that the modified model equations and associated parameters of the cylindrical section and spherical head presented in Table 4 are slightly different from those values given in Table 3. That is to say, if we evaluate each section of the cutter individually by the methods presented in [13,18], the profile error and tolerance will be estimated mistakenly. In more detail, the values of the profile errors and tolerances are smaller than the actual values so that an erroneous diagnosis for profile precision will occur.…”

“…Shunmugan [12] employed the simplex method to resolve the problem of minimum average deviation, f = ͉e max ͉ + ͉e min ͉ + 1/͉e max ͉͉e min ͉, of several features. Dawson [13] analysed the limitations on the techniques used in modern instrumentation and measurement for cylindricity evaluation. Anthony et al [14] formulated the problem of Chebychev best-fit features as nonlinear optimisation problems with complex constraints.…”

Minimum zone evaluation of conicity error using minimum potential energy algorithms

“…Huang et al [9,10] also developed two techniques called CLRS and CPRS for straightness and flatness evaluation based on their work on the geometric minimum zone criteria. Dawson [11] analyzed the limitations on the techniques used in modern instrumentation and measurement for cylindricity evaluation. Shunmugan [12] employed the simplex method to resolve the problem of minimum average deviation, f = |e max | + |e min | + 1/|e max ||e min |, of several features.…”

“…minimizing normal deviation of data points from its surfaces. The aforementioned reports [1][2][3][4][5][6][7][8][9][10][11][12][13] are almost focused in the evaluation of form error of straightness, flatness, cylindricity, circularity and sphericity. The existing method for the evaluation of conicity error is actually infrequent.…”

Qualitative and quantitative evaluation of the accuracy of the V-block method of cylindricity measurements

“…The works available on this subject mainly concern the application of radial methods [1,2]. The radial methods can be divided into two main groups: ones employing a rotary sensor, and ones employing a rotary table (see Fig.…”
