In this study, using ultrafast lasers of 10 ps pulse duration as a precise and efficient method for cutting edge preparation is researched. Cutting edge preparation is an important step within cutting tool manufacturing, while unprepared sharp cutting edges show low stability, which leads to tool failure by high mechanical and thermal loads during the turning processes [C. F. Wyen, W. Knapp, and K. Wegener, Int. J. Adv. Manuf. Technol. 59, 899–914 (2012)]. The rounding of the edges requires laser manufacturing with high precision and minimal heat accumulation; thus, ultrafast lasers have been used in other investigations [M. Stolze, T. Herrmann, and J. L'huillier, Proceedings of ICALEO, Orlando, USA, ICALEO, Orlando, FL, October 23–27 (J. Laser Applications, Orlando, 2011)]. In the authors’ study, the effects of edge roundness on the cutting tool material WC-Co alloy were experimentally investigated. Samples with three different grain sizes and percentages of cobalt were used in the authors’ study. The ex...

基于皮秒激光的刀具刃口制备实验研究

在这项研究中，研究了使用 10 ps 脉冲持续时间的超快激光器作为一种精确有效的切削刃制备方法。切削刃准备是刀具制造中的一个重要步骤，而未经准备的锋利切削刃稳定性低，这会导致刀具在车削过程中因高机械和热负荷而失效 [CF Wyen, W. Knapp, and K. Wegener, Int . J. 高级 制造。技术。59, 899–914 (2012)]。边缘的倒圆需要高精度和最小热量积聚的激光制造；因此，超快激光器已用于其他研究 [M. Stolze、T. Herrmann 和 J. L'huillier，美国奥兰多 ICALEO 会议录，佛罗里达州奥兰多 ICALEO，10 月 23-27 日（J. Laser Applications，奥兰多，2011 年）]。在作者的研究中，实验研究了刃口圆度对刀具材料WC-Co合金的影响。作者的研究中使用了具有三种不同粒度和钴百分比的样品。前...
