? Clay modeling (or clay model making) was started by Harley earl (who was head of GM Styling studio) in 1930s. This design studio was earlier known as Art and color section, then name of this section was changed as design and styling department. Today all cars born with …
There are many di erent methods for acquiring shape data. Essentially, each method uses some mechanism or phenomenon for interacting with the surface or volume of the object of interest. There are non-contact methods, where light, sound or magnetic elds are used, while in others the surface is touched by …
Reverse engineering is a rapidly evolving discipline, which covers a multitude of activities. In this paper we will only be concerned with reverse engineering of shape, but a broader interpretation of the term to involve understanding of design intents and mechanisms is also possible. While conventional engineering transforms engineering concepts …
Zebra mapping maps black and white stripes on objects. In the case of NURBS Models and fitted NURBS Patches, this is useful in reviewing the continuity of NURBS surfaces. In the case of Polygonal Models, zebra mapping is useful when reviewing global surface continuity. The continuity between two adjacent NURBS …
The engineering concept is not new concept but this concept was started in ancient era when man invented the wheel, pulley, lever etc. every modern engineering concept is based on the all old machines like this. Today engineering definitions are also depends on these inventions which were invented in ancient …
Non-uniform rational B-spline (NURBS) is a mathematical formula to represent the curve and surfaces in to the CAD (Computer added Design) NURBS surfaces are very accurate and smooth analytical and freeform surfaces.These surfaces are developed in around 1950 by those engineers who were designing the object like car skins, aircraft …
Today in industrial environment people requires flexible accurate and user friendly measuring equipment. This can help in measure in both environments development as well as in manufacturing. Now there are so many optical measurement devices which work on white light or laser scanning technique. Engineering applications now require the fast …
There is equipment which is specially made for Gap and flush (mismatch) measurement. This equipment is developed by Third dimension software. This is laser equipment. This equipment is heavily and extensively used in automotive and aerospace industry. This equipment is not only measure Gap and flush but it also measure …
1. GD&T give clear concept of defining a part coordinate system on a part or assembly for making accurate and easy understanding through out the manufacturing process. 2. It will help you do the geometrical dimensioning, solve so many design problems 3. It will help you to reduce the drawing …
GD&T meaning is Geometric Dimensioning & Tolerancing (GD&T). This is a language to metrology to define the position of a feature with respect to other reference feature In terms of symbols. Generally in metrology we are measuring a part in following two ways 1. Dimensional checking.2. Position checking.When we are …
