【摘要】 304不锈钢在核电设施及装备建造中广泛使用，在应急救援中使用拆解机器人对其进行铣削拆解时存在刀具生热高、磨损快、表面加工硬化严重、润滑方式受限等问题，合适的铣削参数可有效避免这些问题。研究不同润滑条件下的304不锈钢铣削力与铣削参数的影响规律和量化关系，采用试验方法研究了主轴转速、进给速度、轴向深度等主要铣削参数对铣削力和铣削效率的影响，并采用微量油雾润滑(minimum quantity lubrication, MQL)的方式，在合适的参数区间内开展单因素和多因素铣削试验，对比分析得到主要铣削参数对铣削力的影响规律。试验结果表明，机器人铣削304不锈钢时轴向深度为铣削力主导因素，基于试验结果获得较优铣削参数组合，刀具磨损小、作业稳定性好，可实现核应急拆解机器人高质高效作业。更多还原

【Abstract】 304 stainless steel is widely used in the construction of nuclear power facilities and equipment. When dismantling robots perform milling dismantling for emergency rescue, problems such as high tool heat generation, rapid wear, severe surface work hardening, and limited lubrication methods are encountered. Appropriate milling parameters can effectively avoid these issues. This study investigates the influence law and quantitative relationship between milling forces and milling parameters of 304 stainless steel under different lubrication conditions. Experimental methods are adopted to explore the effects of main milling parameters including spindle speed, feed rate and axial depth on milling force and milling efficiency. Using minimum quantity lubrication(MQL), single-factor and multi-factor milling experiments are carried out within a suitable parameter range, and the influence law of main milling parameters on milling force is obtained through comparative analysis. The experimental results show that axial depth is the dominant factor affecting milling force when robots mill 304 stainless steel. Based on the experimental results, an optimal combination of milling parameters is obtained, which features low tool wear and good operation stability, enabling high-quality and high-efficiency operation of nuclear emergency dismantling robots.更多还原
