约80%用于材料切割的能量在切削区转化为热。这会影响刀具的机械性能，导致刀具加速磨损和刀具失效。由于对可持续和环保加工的日益重视，降低这些温度的努力主要集中在刀具的间接冷却上。本文给出了内冷旋转立铣刀的数学描述。该数学模型得到了计算流体动力学(CFD)模拟的支持，并表明使用内部冷却可以使刀尖温度降低高达65%。
About 80% of the energy used for material cutting transforms into heat at the cutting zone. This affects the mechanical properties of the cutting tool, resulting in accelerated tool wear and tool failure. Due to the increasing focus on sustainable and environmentally friendly machining, efforts to reduce these temperatures have focused on the indirect cooling of the tool. This paper proposes a mathematical description for a rotating end mill with internal cooling. The mathematical model is supported with Computational Fluid Dynamic (CFD) simulations and indicate that up to 65 percent temperature decrease at the tool tip can be by using internal cooling.
