Hard turning has been proved to be more effective and efficient than traditional grinding operations in machining hardened steels. However, rapid tool wear is still one of the major hurdles affecting its wide implementation in industry. Better modeling of the tool wear progression helps optimize cutting conditions and/or tool geometry to reduce tool wear, which can make hard turning a feasible ...

In general, in composting facilities the active, or intensive, stage of the process is done separately from the maturation stage, using a specific technology and time. The pre-composted material to be matured can contain enough biodegradable substrates to cause microbial proliferation, which in turn can cause temperatures to increase. Therefore, not controlling the maturation period during wast...

Most of the current methods of surface characterization provide only measures, parameters and patterns of the data without any prediction of useful information or recommendations for the improvement of surface quality in ultra-precision diamond turning. In this paper, a framework of a knowledge-based system (KBS) is proposed for predictive characterization of surface generation in ultra-precisi...

Quantitative understanding of cutting forces under hard turning conditions is important for thermal modeling, tool life estimation, chatter prediction, and tool condition monitoring purposes. Although significant research has been documented on the modeling of forces in the turning operation in general, turning of hardened materials involves several distinctive process conditions, including neg...

This paper presents the three dimensional (3D) finite element analysis to predict the workpiece displacement amplitude and tool wear in face turning of AISI 1040 steel under dry machining condition. 3D vibration induced turning models have been developed and validated by comparing with experimental results so as to identify the correlation. Extensive experimentation and investigators carried ou...

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 ...
