  • Avoiding Design Problems with Geometric Dimensioning and Tolerancing
    Geometric Dimensioning and Tolerancing (GD &T) has been around since the 1940s, yet it is unappreciated as a way of finding bad designs before parts get made. * Tolerances are a vital part of engineering a product, even one described with a solid model. * Drawings toleranced poorly or incompletely

  • Image Quality
    quality, including resolution, image contrast, depth of field, perspective errors, and geometric errors (distortion). Although the resolution and contrast of an image can be defined individually, they are also closely related. In order to determine their relationship, however, it is important

If one or more of the four strain gages sense different absolute strain values. because of asymmetry in design
  • Computer-aided inspection revs up BMW quality
    measurement machines (CMMs). CMMs collect a sample of discrete points on a part one at a time. The process is slow and does not adequately address surface-to-surface inspection required to verify the accuracy of sheet metal or freeform surfaces. Results are recorded in a 2D geometric dimensioning
  • Case Study: Quality Down to the Last Detail
    to target this position precisely. The joining robot then installs the door so that it meets the requirements for a high-quality vehicle, despite the unavoidable geometric variations due to production tolerances. A particular feature of the EDAG Best-Fit system is that it learns and thus independently

It may not be coincidence that screw threads share a structure with the DNA double helix. The helix is a geometric form at the root of ancient science dating from the time
