Aided Designs

CAD is the process of solving design problems with the aid of computers. This function includes the computer generation and modification of graphic images on a video display, [Pg.28]

The one-piece deck lid, and the one-piece rear end panel, with the addition of a quarter panel section, could become a fully integrated rear end assembly in a single, joint-free molded component. [Pg.29]

With CAD systems, interactive graphics allow the user to communicate easily with the computer in display-screen pictures. With the speed of modern computers, this communication is carried out in real time that is, the computer s response is practically instantaneous. Furthermore, little knowledge of computers is required to operate these user-friendly systems. [Pg.132]

Earlier CAD systems were used primarily to perform automated drafting or to facilitate the solution of simple two-dimensional problems. Interactive graphic systems now allow the user to develop three-dimensional models and to perform a wide range of geometric manipulations and sophisticated analyses. [Pg.132]

Assisting the designer in constructing a model are thousands of software aids that automate many of the tedious tasks consuming so much time in traditional manual methods. With the stroke of the pen or the push of a button, the user can move, magnify, rotate, flip, copy, or otherwise manipulate the entire design or any part of it.. . .  [Pg.132]

Industrial scale polymer forming operations are usually based on the combination of various types of individual processes. Therefore in the computer-aided design of these operations a section-by-section approach can be adopted, in which each section of a larger process is modelled separately. An important requirement in this approach is the imposition of realistic boundary conditions at the limits of the sub-sections of a complicated process. The division of a complex operation into simpler sections should therefore be based on a systematic procedure that can provide the necessary boundary conditions at the limits of its sub-processes. A rational method for the identification of the subprocesses of common types of polymer forming operations is described by Tadmor and Gogos (1979). [Pg.1]

Developments. A variety of process modifications aimed at improving surface finish or weld line integrity have been described. They include gas assisted, co-injection, fusible core, multiple Hve feed, and push—pull injection mol ding (46,47). An important development includes computer-aided design (CAD) methods, wherein a proposed mold design is simulated by a computer and the melt flow through it is analy2ed (48). [Pg.142]

Nonimpact Printing. Interest is growing ia the use of nonimpact styles because of the quickness of color changeover and the abiUty to iaterface these machines to computer-aided design systems. Two basic types exist drop on demand and constant drop techniques. [Pg.375]
