摘要

钛合金材料因其优异的机械性能和耐腐蚀性广泛应用于航空航天、医疗等领域。钛合金的高强度、低导热性及易粘刀的特性使得其在加工过程中面临较高的工具磨损。针对这一问题，本文提出了一种基于精密铣削过程的钛合金刀具磨损预测方法，并结合工艺补偿策略对铣削过程进行优化。通过对磨损的定量分析与影响因素的深入研究，提出了一种自适应的补偿方法，以提高加工精度和刀具寿命。实验验证表明，采用该预测与补偿策略能够显著提高钛合金精密加工的稳定性和效率，减少刀具更换频率，降低生产成本。

Abstract

Titanium alloy materials are widely used in aerospace, medical and other fields due to their excellent mechanical properties and corrosion resistance. However, the high strength, low thermal conductivity, and tendency to cause tool adhesion of titanium alloys lead to significant tool wear during the machining process. To address this issue, this paper proposes a method for predicting tool wear in titanium alloy precision milling and optimizes the milling process by integrating a process compensation strategy. Through quantitative analysis of wear and in-depth research on influencing factors, an adaptive compensation method is developed to improve machining accuracy and tool life. Experimental verification shows that the proposed prediction and compensation strategy can significantly enhance the stability and efficiency of titanium alloy precision machining, reduce tool replacement frequency, and lower production costs.
