Investigations on tool life enhancement of a tungsten carbide turning insert for machining of cast iron component

Abstract

newline Global competitive markets necessitate the demand for products with improved quality, reduced cost and prompt delivery. Among the stages of manufacturing, machining of components is extensively an important stage. The issues in this stage would lead to an increase in manufacturing costs, thereby increasing the cost of the product. Certain machining processes are costly and sometimes are unavoidable in the manufacturing. Hence it is essential to identify and reduce the associated machining costs. This would ensure prompt delivery of high quality products at a competitive price. The associated machining costs can be further investigated and reduced by optimizing the machining conditions and various parameters considered with them. Production costs usually increase with the required tooling costs. Hence an increase in tool life would eventually result in reduced production cost. The selection of appropriate tools would reduce the tool cost, and subsequently the production costs. The effects of tool geometry, cutting conditions and material selection are generally considered for the correct tool selection and its long durable utilization. The accountability and consideration of all these factors and correlating them with each other is the need of the hour with respect to various technological aspects. newlineTurning is one of the significant operations considered among the many stages of manufacturing to produce quality products. The tool inserts used for the turning operation need to be investigated for carrying out effective and quality machining. The associated process parameters are to be further optimized for better machining. In the present research, the machining of automobile brake discs which have been taken for investigation. A thorough study has been conducted to obtain the optimized conditions required for the machining process. newline newline
