One of the challenges facing precision manufacturers and their medical device manufacturing partners is the increasing feature complexity of tight-tolerance parts. These complex geometries can result ...

Profile tolerances are defined in ISO 1101, and profile tolerancing is described in ISO 1660. With profile tolerancing a distinction must be made between tolerancing of the form of lines (symbol and ...

However, in practice the actual sizes are subject to variations, and are therefore statistically distributed (e.g. according to a normal distribution) (Figs 14.2 and 14.3). With this supposition, it ...

To say we are all used to plus/minus tolerancing is a drastic understatement, yet as demands on quality rise, and many parts shrink and become more complex, our old ± may not cut it anymore. We live ...

• Geometric concepts are now much easier to read and understand. • Revisions emphasize use of basic dimensions and geometric tolerancing as the preferred way of controlling the form, orientation, and ...

In manufacturing, the devil is in the details—and the smallest oversight can lead to big headaches. Too often, it’s 4:30 p.m. on a Friday, you find out your trusted machinist is away on a fishing trip ...

Some methods that can improve the process include examining prints and removing information that distracts from the engineers’ design intent. An innovative approach to design intent looks at geometric ...
