Machining Property

ABSTRACT

The consistent overall performance of the Indian economy with the growth engine being the industry rather than the service sector has resulted in Euphoria in the manufacturing fraternity. Even in the machine tool industry, the general trends are marked by increasing globalization, standardization of components and systems, and greater international collaboration. The low costs and leading world class productivity becomes mantra to face the today’s manufacturing environment. The demand for new cutting tools and economy in manufacturing all over the world will rise faster than industrial production as a whole in the near future.

Even though the tool cost share accounts for just 4% of customer’s production cost, the influence of cutting tools on the overall production performance and the quality of end product is much greater. It is estimated that in the coming years Asia is going to be the major cutting tool manufacturer with over 30% market share and India is going to become manufacturing hub for the world. In this scenario, there is no other option for the manufacturing sector other than to concentrate on optimizing machining parameters and developing new tool concepts and methods with use of new materials to cut down on costs.

The manufacturing cost can be minimized by reducing the machining cost through optimization of machining environment (by optimizing the machining conditions) and proper setting of various parameters during machining . Since machining is one of the major cost centres for manufacturing of a product, the production cost can also be reduced by reducing the lead time and speed, feed rate , depth of cut and work piece geometry. These variables govern the economics of machining operations. Therefore an attempt has been made to conduct experimental investigation to find and correlate the technological factors to the economics of the machining process.
