REVIEW STUDY METAL RAPID PROTOTYPING METHODS AND MANUFACTURING TECHNOLOGY PRINCIPLE, APPLICATIONS AND TRENDS ABSRTACT: The rapid prototyping (RP) is a vital manufacturing process to create a successful product, especially in a competitive global market condition. To be competitive, products need to be cheaper, of high quality and adaptive to customer’s changing needs in short time. Rapid Prototyping (RP) layer-by-layer material deposition started during early 1980s with the enormous growth in Computer Aided Design and Manufacturing (CAD/CAM). Rapid prototyping of parts in metal is becoming a familiar step in the development of new products. The process is now starting to migrate to rapid manufacture where extremely complex shapes can be manufactured
Surface finish is one of the prime requirements of customers for machined parts. In most of machining operations the main objective is optimization of surface roughness. The higher value of surface roughness generates on the machining parts and due to rework or scrap results into increase in cost and loss productivity. Surface roughness is major factor in modern CNC milling industry. The purpose of this work is focused on the analysis of optimum cutting conditions to get lowest surface roughness in milling by regression analysis.
Metal joining is a method of joining two or more materials with the aid of some external means. Metals are used in structural applications more than most other materials, so joining of metals and their alloys is an extremely important process in production, construction, and assembly. There are vast requirements of materials joining because of limitation of manufacturing a large or complicated work piece design by conventional manufacturing processes such as casting, forging, rolling, extrusion, etc.. There are many methods to join materials as shown in figure 1 1.1.1 Welding: Welding which is the process of joining two metallic components for the desired purpose, can be defined as the process of joining two similar or dissimilar metallic components with the application of heat, with or without the application of pressure and with or without the use of filler metal. Heat may be obtained by chemical reaction, electric arc, electrical resistance, frictional heat, sound and light energy.
Essential Design Guidelines for Injection Mold Companies Injection molding is one of the most productive ways of plastic product manufacturing. Wide range of material availability and practical product designs increased the business of injection mold companies. More complex design modules became easier. While designing a mold structure, the designer should follow few guidelines. Blueprint of a Mold Manufacturer: The increasing demand for plastic parts and products is quite obvious in all industries.
Introduction The evolution of technology has seen its increasing prevalence in modern warfare, including asymmetrical warfare. Usage of technology have resolves many problems in current military. Technology clearly increases efficiency and productivity thus delivering more for less and with pinpoint accuracy. They are molding the future of war and changing the paradigm of modern warfare tactics and military engagement protocol. In modern warfare the dependence on and interaction with technology is undisputed.
Some experts assert that technological change is beneficial for all groups in our society, which the changes are more evolutionary than revolutionary in nature, and that technology ultimately creates more jobs than it eliminates. It includes innovations sophisticated communication systems, flexible manufacturing systems, computer-assisted design or industrial robots. These modern technologies incorporate powerful and low-cost microelectronic devices that have the potential to increase productivity in office and factory production tasks. From another perspective, there a recurrent fear has been that technological change will spawn mass unemployment. Some experts say that the pace of technological change is accelerating and that thousands of workers in plants and offices are affected as labor saving innovations are diffused more widely.
LHPs with flat evaporators are currently receiving a lot of attentions because they providing more space to spread heat from concentrated heat source. Although flat evaporator LHPs are already used in many electronic equipment but there are still improvements needed to increase the application range. So, LHP with a flat evaporator will be fabricated to investigate its heat transfer characteristics under different operating conditions. Purpose and Objective of the Study The primary objective of the research will be energy efficient thermal management of electronic devices using flat evaporator LHPs. Thermal management of electronic components has today become a major consideration in the design of electronic products.
Product innovation can drive profitability and growth, and help companies succeed even in difficult economic times. Many firms adapt and even transform through the creation of new products. What has become apparent in recent years is that the ability to adapt quickly is a critical factor for entry into the market (Eisenhardt and Tabrizi, 1995). This is why more and more companies view product innovation as critical to the long-term success of the business. In the electronics industry, products are updated very quickly, therefore, a company must continuously innovate and evolve with the times to remain an industry leader in electronics.
Plastic and metal fabrications are used in this manufacturing process and to get a final shape and desired design, there are some methods to follow. Fabrication processes comprise; cutting, forming, machining and welding. We can discuss the advantages and disadvantages of plastic fabrication. Advantages and Disadvantage: Though the results of this process (plastic fabrication) greatly rely on the exceptional uniqueness of the type of plastic used (nylon, acrylic, Plexiglas, etc. ), the process itself has numerous advantages and disadvantages, which are given below: Advantages Disadvantages Reduced Finishing: Unlike most metals, plastics can be colored before fabrication; Finding the need for certain post-effective processes, such as
