摘　　要：在高速钻削猪胫骨过程中,钻削力和钻削温度对改进医疗钻头的设计是非常重要的。研究结果表明:在钻削骨头的过程中,钻削力和钻削温度受进给速度和钻削速度的影响。相比不锈钢麻花钻,带三个切削刃的新型医疗钻头能够取得更小的钻削力和低于47℃的钻削温度。Drilling force and temperature of tibia at the high speed drilling for improving the design of surgical drills are very important.The result shows that the drilling force and temperature are affected by the feed rate and drilling speed,which vary with the drilling depth into the bone.The new surgical drill with three top cutting edges can achieve lower temperature below 47℃ and lower drilling force than with the stainless steel twist drill.

关 键 词：骨头钻削 钻削力 钻削温度 医疗钻头
