Estimation of Cutting Force of Rock Cutting with Conical Picks
A method or formula that can accurately estimate the peak cutting force of rock cutting with conical picks is quite valuable.In this paper,formulas with a simple form and wide application and low error were created by analyzing the existing formulas and experimental data,and the relationships betwee...

| description | A method or formula that can accurately estimate the peak cutting force of rock cutting with conical picks is quite valuable.In this paper,formulas with a simple form and wide application and low error were created by analyzing the existing formulas and experimental data,and the relationships between peak cutting force and rock properties and the cutting depth were clarified.The peak cutting force and cutting depth follow a power law with an exponent between 1.1and 1.5.The uniaxial compressive stress is the most important rock properties affecting the peak cutting force.The formula created in this paper was proved by experiments to be more accurate in estimating peak cutting forces compared to those existing formulas. |
