摘要

采用新型气溶胶评估单元测量颗粒数量和质量浓度，粒度分布从纳米级到微米级。在 CFRP/Ti6Al4V 案例研究中测试了不同的冷却/润滑和气流抽排方案，并测量了颗粒浓度，以评估在遵守当前职业接触限制的情况下，这些方案对生产率和单孔成本的影响。还考虑了刀具寿命、冷却剂和能源消耗以及安全打开机床-刀具门所需的待机时间等实现可持续加工的因素。与 MQL 相比，LCO2 可将刀具寿命提高 40%，同时无需待机时间来排出颗粒，因此在生产率和成本方面都取得了最佳效果。

The impact of airborne emissions from coolants and lubricants on machining costs

A novel aerosol evaluation cell was employed to measure particle number and mass concentration, with a size distribution from nano to micro scale. Different cooling/lubrication and airflow extraction scenarios were tested on a CFRP/Ti6Al4V case study, and the particle concentrations were measured to evaluate their effect on productivity and cost per hole, if current occupational exposure limits are respected. Aspects to achieve sustainable machining like tool life, consumption of coolant and energy, and standby time required to safely open the machine-tool doors were considered. LCO₂ delivered the best productivity and cost results as it improved the tool life by 40 % compared to MQL, while eliminating the need for standby time to evacuate particles.
