Abstract
This study discusses the viabilities and performances of a variety of cutting tool mechanism under various conditions. It highlights the basic issues relating to tool life, tool wear and cutting forces and emphasizes the importance of proper selection of cutting tools in manufacturing of discrete component parts. Continuous search for improved methods herald the need for significant transformation through optimization in terms of improved quality products, high productivity and comparative cost advantage. Replacement and adjusting of machine tool associated with tool failure increase production cost and decrease productivity. There still lies a great significance for continuous optimization of the manufacturing process and study of tool wear mechanism for various categories of cutting tool materials, as our ability to continue the trend for improved materials will be severely tested in the coming decades. It is the failure issues associated with tool wear mechanism of selected cutting tool materials and their essential properties that this work addresses; hence it reveals salient information and this aspect will continue to receive attention in machining processes.
Keywords: Cutting tool mechanism, tool life, tool wear, cutting forces, discrete component parts, significant transformation, optimization
