Most of the orthopedic surgeries require bone drilling, and accurate control of optimal values of parameters influencing the process of bone drilling in robot-assisted orthopedic surgery is important. Bone drilling process including three materials and three diameters of the drill bit, and three drilling depths, four cooling modes, and ten drilling angles were simulated on the tibia and femur bones using the finite element method (FEM). After ensuring the correctness of FEM simulation results using comparison with experimental data, the impact of the above variables on the changes of three parameters of maximum temperature, thrust force and torque, and temperature durability was assessed. The increase of drill bit diameter and drilling depth, and decrease in the drilling angels led to an increase in the aforementioned parameters, and bone drilling conditions become less favorable. The drill bit with stainless steel material and with gas coolants (especially CO₂ coolant) resulted in more optimal bone drilling conditions even in higher drill bit diameter and depth of drilling. The equations between temperature, thrust force, and torque with drilling angles in various cooling modes have been calculated for the programming of drilling robots during orthopedic surgeries to obtain the optimal accurate angle during surgeries.

大多数骨科手术都需要进行骨钻孔，因此准确控制影响机器人辅助骨科手术中骨钻孔过程的参数的最佳值非常重要。使用有限元方法（FEM）在胫骨和股骨上模拟了包括三种材料和三种钻头直径，三种钻削深度，四种冷却方式以及十种钻削角度的骨钻工艺。通过与实验数据的比较确保有限元模拟结果的正确性后，评估上述变量对最大温度，推力和扭矩以及温度耐久性三个参数变化的影响。钻头直径和钻孔深度的增加以及钻进角度的减小导致上述参数的增加，并且钻骨条件变得不太有利。带有不锈钢材料和气体冷却剂（尤其是一氧化碳）的钻头_2种冷却剂）即使在更大的钻头直径和更大的钻孔深度下，也能获得更理想的骨骼钻孔条件。为了在整形外科手术期间对钻孔机器人进行编程，以计算出在各种冷却模式下的温度，推力和扭矩与钻孔角度之间的方程式，以便在手术期间获得最佳的精确角度。
