Solution Improvement for Existing Concrete Formwork Equipment by Using Creative Methods and PLM Concept
The construction domain is an important part of everybody's life consisting of one of the major needs in the Maslow's pyramid: safety. The now-a-days complex, spectacular designed constructions imply new technologies with high efficiency and precise equipment.The paper analyses the optimum solution for the desired product by using the PLM (Product Lifecycle Management) approach, starting by using previous primary and secondary information and pursuing with the solution determination. The conceptual solutions are obtained through creative methods from the specifications-the functions-of the improved product.Hence, having the proper solution that responds to the client's needs we can make the…
Grinding Tungsten Carbide Used for Manufacturing Gun Drills
This paper presents a study of grinding cemented carbide DK460UF (91 % WC and 9 % Co), a material used to produce cutting tools with solid cutting edges. The aim is to establish the manufacturing conditions that lead to high surface quality. A model of the main factors that influence the grinding process is presented first. Following that, grinding wheel wear and surface roughness are analysed. Grinding wheel wear is studied in experimental conditions under which small diameter gun drills were sharpened with two diamond grinding wheels of different grain sizes. Finally, the wear curve can be made. The "G ratio" is used to characterise the performance of the grinding process. Next, the exper…
Optimum Solution for Sliding Formwork Equipment
In the present context of the construction domain where everything needs to respond to the market requirements and time efficiency is an ongoing issue, the paper analyses the optimum solution for a sliding formwork. By using all the previous data obtained through PLM (Product Lifecycle Management) approach, we determined the particular solution. For this creative methods were used.As a future step, by having such solution we can design an intelligent equipment and make a step ahead in the formwork industry.
