Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...

Micromachining is the most basic technology for the production of miniaturized parts and components. Micro turning is one type of micromachining process which uses a solid tool and its material removal process is almost similar to conventional turning operation. The objective of this paper is to provide a state of the art in the field of micro turning. In recent years, researchers have explored...

This paper presents simulation of cutting process by turning of polyamide PA 66, the simulation based on approach Arbitrary Lagrangian Eulerian, ALE. Was taken into account a tool knife CNMA from Coromant. The flow stress of the workpiece is modeled as function of strain, strain rate and temperature, so as to reflect its dynamic changes in physical properties. In this way, the influences of dep...

Product-form solutions in Markovian process algebra (MPA) are constructed using properties of reversed processes. The compositionality of MPAs is directly exploited, allowing a large class of hierarchically constructed systems to be solved for their state probabilities at equilibrium. The paper contains new results on both reversed stationary Markov processes as well as MPA itself and includes ...

Predicting the main cutting force during turning is of great importance as it helps in setting the appropriate cutting parameters before machining starts.Again, optimization of cutting parameters is one of the most important elements in any process planning of metal parts as economy of machining operation plays a key role in gaining competitive advantage. This paper presents an experimental stu...
