Integral model of selection of optimal cutting conditions from different databases of tool makers

Abstract The contribution suggests some possibilities of the determination of cutting conditions for the cutting process. Flexibility and intelligence are indispensable factors in automation and manufacturing. For such demands, intelligent information systems are required, especially considering the technological date type. The process setting parameters have to be determined in the best suitable way. A central point of technological data are the cutting values feed and speed, especially because of their influence on cost, time, quality and security of the manufacturing process. The rapid development of new advanced materials, tools etc. cause the lack of qualified, actual machining values. The integral model represents integration of individual databases in the tool management system. The integral model of selection of optimal cutting conditions presented in the paper was developed from different databases taking into account the limitations of the cutting process. The optimization depends on the data on the workpiece (e.g. dimensions or the required grade of surface roughness), and also the data on the tool and the machine tool.

Organization of tool supply and determination of cutting conditions

Abstract The tool supply system is intended to feed the tools to metal-working machines taking into account the time, quantity, position and target and also the tool removal. As a matter of fact, it represents a subsystem of the superior tool system. For a trouble-free flow the following functions are needed: purchase, arrangement, readiness, pre-setting and maintenance. In this paper, a model is proposed for selection of optimal cutting conditions obtained from different data bases by taking into account the limitations of the cutting process. The developed model selects optimal cutting conditions with respect to the data on the workpiece, such as dimensions and required degree of surface roughness, the data on tool and the data on the machine tool.
