Ever since the plus/minus limits on dimensions first started to appear on engineering
drawings in the early 1900s, tolerances have been one of the most important issues for …

A new mathematical model is presented for representing the tolerances of planar surfaces.
The model is compatible with the ASME Standard for geometric tolerances. Central to the …

The concept of smart manufacturing has become an important issue in the manufacturing
industry since the start of the twenty-first century in terms of time and production cost. In …

Research in feature-based design is reviewed. Feature-based design is regarded as a key
