correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Production and non-productive equipment and personnel delays are a critical element of any production system. The frequency and length of delays impact heavily on the production and economic efficiency of these systems. Machining processes in wood industry are particularly vulnerable to productive and non-productive delays. Whereas, traditional manufacturing industries usually operate on homoge...

Hardened steels are commonly used in wide areas of technologies and industries. In respect of poor machinability of these steels and requirement of expensive cutting tools, study of machining economy is a matter of importance. Thus the present study deals with the economic considerations of various hole making processes. For this purpose, the hard steel samples were machined by conventional dri...

the study assessed economic of maize production in ogori/magongo local government area of kogi state. to this end, effort was made to examine the socio economic characteristics of the maize farmers, determine the resource use efficiency, problems as well as profitability of maize production in the area. to achieve the objectives of this study 48 maize farmers where randomly selected from 5 ward...

In traditional Computer Numerical Control (CNC) systems, machining parameters are usually selected prior to machining according to handbooks or user’s experience. These practices tend to select conservative parameters in order to avoid machining failure and assure product quality specifications. Less conservative practices try to find optimal machining parameters off-line to increase process pr...

8 9 Abstract 10 11 To verify NC programs as well as to optimize the cutting conditions, the importance of machining process simulation system is increasing. 12 The paper discusses new approach for milling operation simulation using enhanced Z map algorithm. To extract the required geometric 13 information from NC code, suggested algorithm uses supersampling method to enhance the efficiency of a...

The tool wear of cutting tools has a very strong impact on product quality as well as on the efficiency of machining processes overall. Despite the current high automation level in the machining industry, a few key issues prevent complete automation of the entire turning process. One of these issues is tool wear, which is usually measured off the machine tool and is still done by hand under a t...

The paper describes the concepts that must be considered in order to achieve a flexible manufacturing system that allows introduction of new products and new resources without total reprogramming of the control system. The basic structure of a resource model is presented and also guidelines for achieving a generic resource model. The description of how to manufacture the products is also essent...
