Manufacturing Process Selection

A computer-aided design system for suggesting candidate manufacturing process and material combinations for a part is described. The system uses an interactively generated twelve-digit classification code to eliminate unsuitable combinations from consideration and rank the remainder. The ranking system is still under development.

Laser additive manufacturing is an advanced manufacturing process for making prototypes as well as functional parts directly from the three dimensional (3D) Computer-Aided Design (CAD) model of the part and the parts are built up adding materials layer after layer, until the part is competed. Of all the additive manufacturing process, laser additive manufacturing is more favoured because of the advantages that laser offers. Laser is characterized by collimated linear beam that can be accurately controlled. This chapter brings to light, the various laser additive manufacturing technologies such as: - selective laser sintering and melting, stereolithography and laser metal deposition. Each of these laser additive manufacturing technologies are described with their merits and demerits as well as their areas of applications. Properties of some of the parts produced through these processes are also reviewed in this chapter.

Choosing appropriate manufacturing processes to create functional surfaces is a challenging issue for some industrials. A specific surface finish can be obtained by different manufacturing processes, each of them having a different economic impact. Currently, no tool could guarantee the surface function through the choice of a manufacturing process and its associated operating parameters. This paper aims at discussing about a framework of models for selecting conventional or innovative manufacturing processes and their associated parameters with regards to surface topographies and textures. To achieve this, a concept of decomposition of database is introduced. Manufacturing processes such as, electro discharge machining, water jet machining (used for texturing surfaces), sandblasting and laser cladding are modelled. Finally, a concept that links such a database with computer aided design (CAD) software in order to integrate surfaces functionalities and manufacturing processes directly into the design step is discussed.

Aided Design

At the end of the manufacturing process, engineers need to know if a manufactured part fits its computer-aided design (CAD) model and how is the amplitude of inherent variation of manufacturing process. Non-rigid parts, at free state condition, may have a significant different form than their CAD model due to gravity loads; residual stresses induced distortion and/or assembly load. Today, a complicated and expensive specialized fixture is needed to conform these parts. To tackle the above challenges, we present in this paper a new approach for metrology of fixtureless non-rigid parts. This approach combines the curvature properties of manufactured parts with the extreme value statistic test as identification method to distinguish profile deviation due to the manufacturing process from part’s deformation due to the flexibility of the part and to determine whether the tolerance fits the CAD model or no. This approach is tested on simulated typical industrial sheet metal giving satisfying results in terms of percentage of errors in defect area and in peak profile deviation estimated.

In this paper, we present different points of view to make the sheet metal and micro-wave product as manufacturing friendly as possible. Within DFM(A)-research (Design for Manufacturing and Assembly), engineering design and manufacturability of Micro-Wave (MW) and sheet metal products has been studied. Other aspects of DFM(A) have risen from novel material applications and the development of CAD (Computer Aided Design) environments. In this paper, practical examples are presented to show how to apply DFMA-rules to MW- and sheet metal components, in particular, and how to develop DFM(A)-rules for these purposes.

The use of robotics in the industrial environment has, in general, very similar goals. Because of productivity requirements, or due to reliability, industries have been constantly equipping their floor with robots. In that sense, the chapter observed—in a fiberglass company—the chance of using a robot to execute a boring and repetitive task. The task mentioned is, actually, the manufacturing of fiberglass reinforced plastic (FRP) molded grating. To confirm the possibility of using a robot to this job, a cost and time analysis was made about the whole molded gratings manufacturing process. Afterward, research about robotics was taken in parallel with the conception of the robot (named “roving-robot”). Calculations were made to the mechanical project of the robot. Applying computer-aided design (CAD), technical drawing and bill of materials were generated to permit the robot assembling. All of these project steps are presented in this chapter.
