摘要: 基于Allvac 718Plus高温合金铣削刀具磨损规律,研究了刀具磨损对铣削精加工表面完整性各指标的影响规律,并结合具体的试件疲劳性能测试实验分析了刀具磨损对试件疲劳性能的影响规律和作用机理,得出Allvac 718Plus材料精铣参数下刀具后刀面磨损量的控制范围不超过0.15 mm,获得了影响试件疲劳性能的主要影响因素。相关研究成果为控制Allvac 718Plus试件精加工的表面完整性和刀具磨损量提供了参考。

Abstract: Based on the premise of Allvac 718Plus superalloy milling tool wear law, the influence rules of tool wear on the indicators of fine milled surface integrity were studied,and combined with specific fatigue performance tests of specimens, the influence rules and mechanism of tool wear on the fatigue performance of specimens were analyzed. It is obtained that the control range of flank face tool wear under the parameters of Allvac 718Plus fine milling is less than 0.15 mm, and the main influencing factors on fatigue performance of the specimens are also obtained. The relevant research results provide a reference for controlling the surface integrity and tool wear of Allvac 718Plus specimens in fine machining.

Key words: Allvac 718Plus superalloy, tool wear, surface integrity, fatigue life
