Design and optimization of a cutting parameters for composite materials in drilling process

Abstract

The cutting forces generated in metal cutting have a direct contact on heat generation, surface quality of work piece and accuracy of the work piece. A milling tool dynamometer that can measure static and dynamic cutting forces has been used for optimization. The orientation of octagonal rings and strain gauge locations has been determined to maximize sensitivity and to minimize cross sensitivity. The dynamometer is connected to a data acquisition system. Cutting force signals were captured and transformed into numerical form. It is processed using a data acquisition system consisting of necessary hardware and software running on a computer. The acquired results of machining tests performed at different cutting parameters represents that the dynamometer could be used to measure cutting forces. Though the dynamometer was developed primarily for drilling operations, it can be used to measure cutting forces in all machining operations such as turning, drilling, grinding, shaping etc.
