硬质合金刀具材料主要物理力学性能对钛合金铣削加工的影响
|
摘要
本文主要研究了硬质合金刀具材料的物理力学性能对其铣削钛合金表现的影响。两种含钴量(分别为13%和12%)和晶粒度(分别为0.5μm和0.4μm)相近的超细硬质合金材料具有不同的韧性、强度和硬度,并被同时用于铣削Ti-6%Al-4%V钛合金。结果表明使用强度和韧性较好的合金制成的刀具耐用度更高,更合适用作钛合金铣刀的基材。这主要由于与普通钢材(如45#钢)相比,钛合金铣削加工时的切削阻力更大,需要刀具材料足够强韧来支持切削过程中刀具刃口的完整性。
This work investigates how the physical properties of cemented carbides affect their performance on titanium milling. Two grades of WC-12%Co fine-grain cemented carbide with different hardness and toughness were used to mill Ti-6%Al-4%V titanium alloy. The result shows the cemented carbide with higher toughness has a longer tool lifespan, and could be a better candidate as cutting tool materials for titanium milling. This mainly attributes to higher cutting force during titanium milling compared with general steel.
