All modern manufacturing units are striving to develop a cost-effective product with optimized reduced weight by using CAE driven design process. In this scenario the product design is stimulated by structural optimization tools like geometrical (topology) optimization, shape optimization or size optimization. For conservation of natural resources and optimum energy utilization, weight reduction has been the main focus of machine tool manufacturers in the current state. Weight reduction can be achieved by the introduction of suitable material, manufacturing processes and design optimization. Geometrical optimization has developed an integral tool of product design and development. Geometry assisted design model gives optimized results which are better and innovative in terms of product design with improved structural performance and stability. Also, rapid prototyping has been used over traditional manufacturing and forming for the pattern making process which helps to reducing material wastage and time associated with tooling. The weight of guide bracket reduces from 2.7kg to 2.0kg. The maximum displacement is reducing from 0.016mm to 0.013mm.
