利用变切深法提高铣刀耐用度的实验研究

摘要

采用涂层硬质合金刀具对Aer Metl00超高强度钢和TB6钛合金分别进行固定切深和变切深铣削实验,对比分析了固定切深和变切深两种铣削方式对刀具耐用度的影响.结果表明:固定切深产生边界磨损,而变切深产生均匀磨损,采用变切深方法加工Aer Met100钢和TB6钛合金,提高刀具的耐用度可提高50％以上.%Two different milling experiments (fixed cutting depth and variable cutting depth) on Aer Met 100 super high strength steel and TB6 titanium alloy are carried out by using coated cemented carbide tools. The effects on tool life by fixed depth cutting and variable depth cutting are analyzed. The results show that the boundary wear appears when the fixed cutting depth is used, while the u-niform wear appears when the variable cutting depth is used. The variable cutting depth is applied to milling Aer Met 100 steel and TB6 titanium alloy, the tool life can be improved more than 50%.
