Adaptive control system is a logical extension of the CNC-mechanism. In CNC mechanism the cutting speed and feed rates are prescribed by the part programmer. The determination of these operating parameters depends on the Knowledge and experience regarding the work piece, tool materials, coolant conditions and other factors. By contrast in adaptive control machining, there is improvement in the ...

Quality and productivity are two important aspects that are inter-related in any machining operation The objective of this work is to estimate the influence of machining parameters and to determine their optimum conditions in manufacture of cast-iron disintegrated flywheel. The parameters considered are speed, feed and depth of cut where as the response are material removal rate and surface rou...

Electro Chemical Discharge Machining (ECDM) is an emerging hybrid machining process used in precision machining of hard and brittle non-conducting materials. The present paper gives a critical review on materials machined by ECDM under the prevailing machining conditions; capability indicators of the process are reported. Some results obtained while performing experiments in micro-channeling on...

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 ...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

In finish-machining, geometric accuracy and surface quality m adversely affected by the tool wear at the minor flank and nose area. This paper describes an investigation into "comprehensive" tool wear estimation, including flank-, crater-. minor flank-, and nose-wear, based on an analysis of dynamic cutting force in oblique machining. The force, measured in terms of its three orthogonal compone...

The relationship between machining speed and the process mean for a manufacturing process has received little attention. This paper presents an analytical model and its solution procedure to simultaneously determine the optimal machining speed and process mean when the objective is to minimize the total cost per part. The total cost of the model includes replacement (resetting), production and ...

Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...

In machining to improve machinability, productivity and to extend tool life coolants and lubricants where used .Increasing industry the use of cutting fluids subsequently increasing this leads in reduce of living conditions nearby future all the governments recommend the manufacturers to reduce the usage of toxicity cutting fluids. Still research for dry machining challenge is exiting for the i...
