摘要:
基于高速加工和流体动压理论,提出了利用高速多轴机床和高速工具约束磨料对零件表面进行可控精密光整加工的方法.首先,利用流体动压理论建立了工具与工件构成的楔形区流体速度场与压力场的数学模型,从理论上探讨该工艺方法实现的可能性.然后,通过实验验证了该工艺方法的有效性.在此基础上,研究了工具转速、走刀速度、工具与工件间隙、磨粒型号等因素对光整加工效率与效果的影响.最后,通过正交试验法得到光整效率与效果较好的工艺:粗光整时,间隙量为0.15mm,混合液选用1份80#研磨抛光膏与10份40#润滑油配比;精光整时,间隙量为0.05mm,选混合液用1份800#研磨抛光膏与5份40#润滑油配比;镜面光整时,间隙量为0.02mm,混合液选用微粉磨料W5与煤油、石油磺酸钡配比;工具转速均采用机床最高转速,走刀速度均选择1000mm/min.研究表明,高速工具约束磨料光整加工方法可行且有效.
Abstract:
Based on high-speed machining and hydrodynamic lubrication theories, a controllable finish machining method on the surface of workpiece by using the high-speed multi-axis machine tools and high-speed tool restrained abrasives is proposed. First, the mathematical model of the fluid velocity field and pressure field on the wedge zone between the high-speed tool and the workpiece is established by hydrodynamic theory. It is proved theoretically that the process can be put into practice. Then the validity of the theoretical research is proved with experiments. Furthermore, the effects of the factors such us the tool rotational speed, feed rate, gap between tool and workpiece, abrasive specifications, etc. on the efficiency and the effectiveness of the finishing process are studied. Finally, better process data on various finishing processes are obtained with orthogonal experiments. The data of rough finishing are 0.15mm in spacing and one portion of 80# polishing paste with ten portion of 40#lubricating oil are used for mixture.The data of fine finishing are 0.05mm in spacing and one portion of 800# polishing paste with five portion of 40# lubricating oil are used for mixture. The data of glossy finishing are 0.02mm in spacing and W5 fine powder abrasive with kerosene, petroleum barium sulfonate for mixture.The maximum speed of the machine is used as tool rotational speed and the feed rate is 1000mm/min.It is shown that the finishing process with high-speed the tool constrained abrasives is effective.
