In general, the specifications analyzed using this approach are form tolerances such as cylindricity, circularity or flatness and zone flatness.
[7] investigated the influence of cutting parameters (depth of cut, cutting speed, feed rate, helix angle, number of blades, margin size and rake face) on real diameter, roundness, cylindricity and surface roughness during reaming aluminium-silicon alloy.
B.M.Umeshgowda found that a drill bit of diameter which has a minimum value of 6mm is required to minimize the dimensional deviation, Feed rate has a greatest impact in the cylindricity than circularity,so from the optimized condition the minimum deviation of the circularity, cylindricity and the minimum value of surface roughness areobtained [2].
The circularity, cylindricity, surface roughness and hole oversize of the ultrasonically and conventionally drilled work pieces were measured and compared.
As they develop smaller and more complex products with tight tolerances and tough-to-machine materials, OEMs are eager to maximize productivity, reduce scrap, and maintain very tight run-out, diameter, true position and cylindricity specifications.
The cylindricity of this hole (or straightness) characterizes the straightness error of the z-axis motion.
The company's Mitutoyo RA2100 Roundness Tester makes light work of measurements including cylindricity, concentricity and perpendicularity (as well as other more specialist measurements), added to which, the flexible design of the equipment allows for set-up of an extensive range of different geometries.
presented a straightforward, easy-to-use graphical approach known as the "Catena" method for tolerance stack analysis, involving geometric characteristics in form control--flatness, straightness, circularity and cylindricity. No complicated mathematical formulae are required in deriving the solution.
As a result, rotational accuracy--the key to roundness/ cylindricity measurement--is described as "world-class" at (0.02+3.5H/10000) pm.
Mahr Federal has also introduced a new version of its MMQ 200 Formtester Cylindricity machine with an automated T7W probing system.
