A reliable and sensitive technique to monitor the tool wear without interrupting the process became a crucial issue for realization of the modern manufacturing concepts without human resources at machining centers. A proper oniine cutting tool condition monitoring system is essential for deciding when change the tool. This paper outlines a neural network based tool condition monitoring system for cutting tool flank wear. The cutting tests were performed on mild steel using HSS tool and on-line cutting forces data was acquired with a cutting force dynamometer. Simultaneously flank wear was measured using a toolmakers microscope and the processed data were fed to a Back Propagation Neural Network (BPNN). The developed system then was tested to predict flank wear for various cutting conditions. The output of the neural network is capable of accurate tool wear prediction for the range it had been trained but the accuracy deteriorated as the cutting conditions were changed significantly.- Improvement of Dynamic Behaviour of Boring Tools Using Lead Damper and Impact Damper

In the turning operation, chatter or vibration is a frequent problem, which affects the surface finish and tool life. In all cutting operations like turning, boring and milling vibrations are induced due to the deformation of the workpiece, this implies economical disadvantage. The main objective of the proposed work is to design damped tool holder for existing machine tools with low cost fabrication techniques. In this investigation, improvement of the damping capability of boring tool and suppression of chatter vibration using lead damper and Impact damper are analyzed. The lead damper Inertia mass of the boring tool has been Increased to suppress the chatter vibration. In impact damper kinetic energy of free mass is dissipated. Finite element analysis is performed to study dynamic behavior of composite tool holder, the effects of overhang length of boring tool with lead damper, and the effects of impact damper in boring tool was investigated.- Continuous Improvement:Kaizens for Waste Minimization

Continuous Improvement (CI) has been incrementally induced in a corporate thinking; however, practical implementation o f Cl In the manufacturing process has progressed at a slower space. This research attempted to implement Cl in the foundry by using the concept of kaizen. The purpose o f this research is to expound waste minimization in a foundry and to reveal their positive influences on continuous improvement environment. A sand casting case is presented to validate and demonstrate the dynamics of Cl implementation process in the foundry and practical approaches adopted during implementation are also discussed. This case study shows that Cl process is a specific tailor made process for a selected organization and Cl is a cyclic nature of never ending gradual improvement process.- Optimization of Parallel Machine Scheduling (PMS) using Intelligent Techniques

Optimization of parallel machine scheduling in a shop floor environment is considered with the objectives of minimizing both the total earliness and the total tardiness. A hybrid optimization procedure based on genetic algorithm and fuzzy logic technique has been developed in this work in order to achieve the multi-objective functions. The proposed optimization procedure is compared with the existing heuristics and the performances are analyzed.- Technological Inputs for Improving Productivity in the Cast Iron Foundry:Finite Element Simulation Strategies
