摘要：We studied the process of cutting the worn pneumatic Bridgestone tire the size of 7.1/11.0-5 using the cutting tool made of alloys of grades R6M5 and T15K6, resulting in the obtained data array on the reduced cutting forces. Regression coefficients were calculated, which formed the basis of a mathematical model in the form of a second-order polynomial. The constructed mathematical model expresses cutting forces dependence on the totality of geometrical parameters and hardness of the cutting tool’s material and operational parameters of the cutting process. Using it can help determine the combination of optimal geometrical parameters, material of the cutting tool and operational parameters in order to ensure the minimization of cutting forces and energy consumption for the cutting process as a whole.The mathematical model was refined based on the obtained equation of cutting force dependences on tensile strength of the materials of automobile tires. The adequacy of the refined model was confirmed by estimating homogeneity of variances of the estimated and experimental values of cutting forces by using a statistical Fischer criterion. We determined effective operational parameters: spindle rotation frequency and cutting tool feed; geometrical parameters and hardness of the cutting tool’s material, which ensure minimal power consumption when cutting worn automobile tires.
