钛合金 TB6属高强高韧近β型钛合金,具有良好的铸锻性和淬透性,目前应用非常广泛。通过顺逆铣、新刀或磨损刀一次铣削和二次铣削试验,研究了钛合金 TB6(Ti-10V-2Fe-3Al)加工硬化和加工硬化层深度。研究结果表明,用硬质合金刀片铣削钛合金 TB6,顺铣比逆铣加工硬化和加工硬化层深度小,新刀比磨损刀加工硬化小,新刀加工硬化层深度<25μm,刀具磨损量 VB=0.3 mm 时,磨损刀加工硬化层深度最高可达81μm,其二次铣削将导致已加工表面软化。
鈦閤金 TB6屬高彊高韌近β型鈦閤金,具有良好的鑄鍛性和淬透性,目前應用非常廣汎。通過順逆鐉、新刀或磨損刀一次鐉削和二次鐉削試驗,研究瞭鈦閤金 TB6(Ti-10V-2Fe-3Al)加工硬化和加工硬化層深度。研究結果錶明,用硬質閤金刀片鐉削鈦閤金 TB6,順鐉比逆鐉加工硬化和加工硬化層深度小,新刀比磨損刀加工硬化小,新刀加工硬化層深度<25μm,刀具磨損量 VB=0.3 mm 時,磨損刀加工硬化層深度最高可達81μm,其二次鐉削將導緻已加工錶麵軟化。

TB6 titanium alloy with high strength and toughness is like beta titanium alloy,and it has good casting,forg-ing and hardenability.The present application of it is very extensive.Experiments on titanium alloy TB6 (Ti-10V-2Fe-3Al) working hardening and working hardening layer depth are studied by down or up milling,with first milling or quadratic mill-ing in a new tool or the wear tool.The results show that titanium alloy TB6 is milled in carbide cutting tools and down mill-ing in work hardening.The work hardening layer depth is smaller than up milling,new tool in work hardening is smaller than wear tool,the work hardening layer depth is less than 25 μm in new tool;the work hardening layer depth is up to 81μm and quadratic milling causes the machined surface softening when tool flank wear VB is 0.3 mm.
