Profile analysis of complex curves, such as airfoils
CMM's had been used by a large engine component manufacturer for the profile analysis of large turbine blades. The process was both accurate and reliable. However, when the volume of blades being produced increased to a level where the cycle time of the CMM became a problem, the manufacturer turned

Texture and Microstructural Gradients in an Extruded Aluminium Profile (.pdf)
OIM measurements were used to investigate the texture and microstructural gradients observed in extruded aluminium profiles. The material used in this study was an AlMgSi-alloy containing 0.45 wt% Mg and 0.44 wt% Si extruded into a flat profile with a cross section of 207 x 3 mm2 carrying a fully

Precise moves depend on ball-screw threads
can significantly influence its precision and material properties, especially fatigue resistance. Lead deviation, bearing journal run-out (or concentricity with the ball tracks), thread roundness, lead wobble, profile tolerances, and surface roughness all are affected by the manufacturing method

Pinpointing assembly Variation
. Hence, the surface profile on the bracket contributes most to variation in the top gap. The column headings need some explanation. For instance, Tol. entries are the names assigned to tolerances in the model that contribute to a measurement. Point items are names assigned to the contributing tolerance

Avoiding Design Problems with Geometric Dimensioning and Tolerancing
and datum references settled, it’s usually a simple matter to choose a geometric characteristic symbol. The type of product feature to be controlled and the type of control (form, profile, orientation, location, or runout) will usually narrow the field to one or two symbols. The geometric feature being

Gear Tooth Form
20% less than full-depth teeth. Full-depth teeth have a larger contact ratio than stub teeth. Gears with small numbers of teeth may have an undercut so they do not interfere with one another during engagement. Undercutting reduces the active profile and weakens the tooth. Mating gears with long
