The Ni-base single crystal superalloy DD5 is commonly employed in critical parts of turbine blades and disks aeronautical engines. To improve the surface machining quality, single-factor experiments were carried out to investigate changes grinding force, morphology, chip morphology under different conditions (dry, conventional flood, minimum quantity lubrication). showed that flood lubrication ...

Tool wear and surface roughness prediction plays a significant role in machining industry for proper planning and control of machining parameters and optimization of cutting conditions. This paper deals with developing an artificial neural network (ANN) model as a function of cutting parameters in turning steel under minimum quantity lubrication (MQL). A feed-forward backpropagation network wit...

The application of emulsion for combined heat extraction and lubrication requires continuous monitoring of the quality of emulsion to sustain a desired grinding environment; this is applicable to other grinding fluids as well. Thus to sustain a controlled grinding environment, it is necessary to adopt an effectively lubricated wheel-work interface. The current study was undertaken to assess exp...

Minimum Quantity Lubrication (MQL) is a cooling and lubrication variant applied, for instance, in drilling processes. In the present approach, new vibration-assisted process analyzed, which has considerable potential manufacturing of extremely hard materials. Within this process, MQL gas/liquid transport presence vibrating rotating twist drill bit borehole to be studied. Multiphase computationa...

This paper aims to find the key process parameters for machining different parts of an automobile gearbox, commissioned by a company that needs to replace with the MQL lubrication system their current machining process based on cutting fluids. It particularly focuses on the definition of appropriate cutting parameters for machining under the MQL condition through a statistical method of Design ...

Minimum quantity lubrication (MQL) based machining methods are widely used in industry now-a days as they environment friendly and save cutting fluid costs. In the present work to augment the advantages of MQL in turning, a bi-objective optimization of process parameters in MQL turning is presented. The optimum selection of process parameters in turning has a significant role to ensure quality ...

Metalworking fluids (MWFs) are harmful to the environment and to the health of workers, resulting in pressures to re-design them in accordance with sustainable manufacturing principles. In this paper, we review research being performed at the University of Michigan to minimize the life cycle environmental and health impacts of metalworking fluids while simultaneously improving manufacturing per...

Tribotechnical diagnostics as an integrated conception deals with the assessment of lubricants properties, monitoring of behaviour and consequences of the lubricant degradation process during its work in the machine lubrication system. For tribodiagnostic of friction pairs of aircraft engine are used three basic methods dealing with the qualitative and quantitative determination of wear particl...
