The Cost

It has conducted a study on the cost calculation of spray component mould manufacturing process. In general, it is the present state that calculating machining time and cost for a unit process in mould manufacturing process depends on past experiences. In other words, it does not go beyond the level of computing and management by estimation based on the data conducted in the past. Accordingly, in the development of mould and new products tried for the first time, the cost calculation is not reasonable and thus a lot of time is needed. That is to say, not being able to actively and reasonably respond to the needs of the market that are changing every moment, the loss of management and money due to losing opportunities is frequently taking place. In this context, It have developed and applied a system that can reasonably calculate the cost by taking account of machining time calculation theory, machine, tool, material and working environment. As a result, calculating the time needed for a unit process in mould manufacturing process is possible, and it is possible to classify major processes and suggest alternatives in management. The system developed in this study used Visual Basic Language and SQL Database under Windows environment.

Limited Role

Today’s manufacturing companies are burdened with the pressures of managing their products throughout its life cycles and ensure that their products have minimum impact in the environment through Eco-design methods. This paper looks into the different Product Eco-evaluation methods in terms of Material Recyclability, Manufacturing Process and Disassemblability used for Eco-design, especially in the automobile industry. From these methods, the authors propose an Eco-Design framework suited for Malaysian local automobile SMEs given their limited role in Automobile design.

Poor Adhesion

Pulse microelectrochemical machining (ECM) by bipolar current is a method allowing the manufacturing of microholes and micropatterns. In many cases, microholes with parallel walls and accurate micropatterns can only be manufactured with the application of an electrically isolating coating to the side surfaces of the cathode. The goal of this research was to find a durable coating for this process. Epoxy resins, Teflon, and diamond-like carbon are considered as dielectric cathode coatings. Different aspects of the working environment of these coatings in the pulse bipolar ECM process, such as electric field, chemical composition, and physical influences of the electrolyte, are analyzed. The main reasons for the low process durability of coatings are poor adhesion and harsh chemical and physical environments. The most promising coating for the process is diamond-like carbon, which shows significantly better performance than the other coatings. Improved adhesion of a coating to the cathode can dramatically improve its durability in the pulse bipolar ECM environment and therefore permits an efficient manufacturing process.

The quantitative evaluation of cluster wind power output volatility and source-load timing matching is vital to the planning and operation of the future power system dominated by new energy. However, the existing volatility evaluation methods of cluster wind power output do not fully consider timing volatility, or are not suitable for small sample data scenarios. Meanwhile, the existing source-load timing matching evaluation indicator ignores the impact of wind power permeability on the timing matching degree between wind power output and load. Therefore, the authors propose quantitative evaluation methods of cluster wind power output volatility and source-load timing matching in regional power grid. Firstly, the volatility-based smoothing coefficient is defined to quantitatively evaluate the smoothing effect of wind-farm cluster power output. Then, the source-load timing matching coefficient considering wind power permeability is proposed to quantitatively evaluate the timing matching degree of regional wind power output and load, and the corresponding function model of volatility-based smoothing coefficient and source-load timing matching coefficient is established. Finally, the validity and applicability of the proposed methods are verified by MATLAB software based on the actual power output of 10 wind farms and actual grid load in a certain grid dispatching cross-section of northeast China. The results demonstrated that the proposed volatility-based smoothing coefficient can accurately represent the smoothing effect of wind farm cluster power output while maintaining the volatility continuity of wind power output time series and without affect from the data sample size. The source-load timing matching coefficient can accurately characterize the difference in the timing matching degree between wind power output and grid load under different wind power permeability and the influence degree on grid load.
