Questions design engineers ask about machined parts, sorted by part type and by topics that cut across part types, such as quality, heat treatment and surface treatment. Each topic gives the answer first, then shows the problem and a better approach in drawings.
Shafts, pins & rods
Questions design engineers ask about machined shafts, pins and rods, from fits and grooves to surface treatment, answered with drawings.
Gears, hubs & rotating parts
Questions design engineers ask about gears, hubs and other rotating parts, from concentricity to grinding and heat-treatment distortion, answered with drawings.
Housings & structural parts
Questions design engineers ask about machined housings, brackets and structural parts, from tolerance stack-up to lightweighting, answered with drawings.
Quality & measurement
Questions design engineers ask about datums, measuring conditions and tolerances that production can hold, answered with drawings.
