Abstract: Accurate estimation of cutting forces is crucial for optimizing machining parameters, improving tool life, and enhancing productivity in milling operations. In this research paper, we present the development and validation of an independent dynamometer system designed for precise measurement and estimation of cutting forces during milling. The proposed dynamometer system offers several advantages, including enhanced accuracy, independence from machine tool structure, and compatibility with various milling configurations. The paper details the design and construction of the independent dynamometer, including the selection of sensing elements, structural components, and signal conditioning circuits. Calibration procedures are outlined to ensure accurate measurement of cutting forces across a range of machining conditions. Experimental validation of the dynamometer system is conducted using a series of milling tests on different work piece materials and cutting tool geometries. The obtained force data are compared with reference values obtained from commercial dynamometers to assess the accuracy and reliability of the proposed system. The results demonstrate the effectiveness of the independent dynamometer in accurately estimating cutting forces in milling operations. The system exhibits minimal interference with the machining process, ensuring reliable measurement without compromising machining performance. Furthermore, the independent nature of the dynamometer allows for easy installation and integration into existing milling setups, offering flexibility and versatility in research and industrial applications. Overall, this research contributes to the advancement of machining technology by providing a robust and accurate solution for cutting force estimation in milling operations. The developed independent dynamometer has the potential to facilitate process optimization, tool wear monitoring, and quality control in various milling applications, thereby enhancing manufacturing efficiency and competitiveness.
