machining operation is one of the most applicable processes for the manufacturing of industrial parts. usually, the quality of finished part in turning operation is measured in terms of surface roughness. in turn, surface quality is determined by machining parameters and tool geometry specifications. the main objective of this study is to model and optimize machining parameters and tool geometr...

This paper reports on a design process of e-learning courses for competence development of experienced employees in the manufacturing industry. Through a crossorganizational collaborative action design research project the aim was to design e-learning courses at university level to support work-integrated learning. Two designand learning cycles were evaluated over two years. The first cycle ide...

Our life is strongly linked with the usage of natural resources. Energy is a necessity in everyday life and is often generated using non-renewable natural resources which are finite. Energy consumption in manufacturing industry is increasing and the way it is consumed is not sustainable. There is great concern about minimizing consumption of energy in manufacturing industry to sustain the natur...

During the last century the steel industry was influenced by several crises which invoked strong innovation activities in development of new classes of steels. innovation was based on the statement of representative of automotive industry bernhard rolinson who said: “Steel has a long tradition but despite of this its potential from the point of view of material properties is exploited only to 2...

ABSRACT High speed machining is a relatively new production technology that allows higher productivity, excellent surface finish and good dimensional accuracy in the manufacturing process. Therefore these technologies have considerable advantages over traditional machining technologies. Instead of conventional machining chain that consists of roughing in soft state + semi fininshing + hardening...

machines using ball end mill cutters; the determination of the optimum tool and the minimization of the machining times for each surface. In the proposed methodology, the accessibility problem is first analyzed and then the optimal tool is selected from a database of tools. Next, and depending on the machining method, we select automatically the optimum sweeping method and the associated machin...

Laser milling provides a new method of producing components for the micro tool manufacturing industry. This paper considers the technical capabilities of laser milling when applied to the machining of components for micro tooling. Characteristics important for laser milling as a micro tooling manufacturing process are reviewed. These characteristics are surface finish, aspect ratio, dimensional...

The objective of this study was to measure formaldehyde present in the atmosphere of a machine shop using a water-based emulsion metalworking fluid containing the formaldehyde-generating antimicrobial agent methylenebismorpholine. Measured formaldehyde values were compared to estimated atmospheric values calculated from vapor-liquid equilibrium (evaporative) and aerosol (mist) generation. Good ...

Cutting fluids have seen extensive use and have commonly been viewed as a required addition to high productivity and high quality machining operations. Cutting fluid related costs and health concerns associated with exposure to cutting fluid mist and a growing desire to achieve environmental sustainability in manufacturing have caused industry and academia to re-examine the role of these fluids...
