摘要
氧化铝工程陶瓷因具有优越的热物理特性和机械性能,在现代制造业中得到了广泛应用。为研究脉冲激光辅助车削氧化铝陶瓷的表面质量,利用自行设计的脉冲激光加热辅助切削系统对热压96氧化铝陶瓷进行加热辅助车削试验。采用正交试验对影响加工表面质量的因素进行了研究,得出脉冲激光辅助切削的最佳参数组合以及激光功率、脉冲频率、机床转速和进给量对表面粗糙度和表面缺陷的影响规律。结果表明,进给量对表面粗糙度值的影响最大,达到41.97%,在最佳参数组合,即激光功率为50 W,机床转速为510 r/min,脉冲频率为50 kHz,进给量为0.01 mm/r条件下进行加热辅助切削试验,工件可以获得较小的表面粗糙度值和较少的表面缺陷。
Abstract
Alumina engineering ceramics have been widely used in modern industry for their superior thermal physical and mechanical properties. In order to study the surface quality of alumina ceramics during pulse-laser assisted turning, experimental investigations are conducted on pulse-laser assisted turning of hot-pressed 96 alumina ceramics. Based on the orthogonal experiment method, optimum operating conditions are achieved, and the influences on surface roughness and defects during pulse-laser assisted turning of alumina ceramics are attained under different parameters such as laser power, pulse frequency, rotational speed and feed. The results indicate that the feed makes the major contribution to overall turning performance, which reaches 41.97%. Good surface roughness and less surface defects can be achieved under the optimum operating conditions, which are laser power of 50 W , rotational speed of 510 r/min, pulse frequency of 50 kHz and feed of 0.01 mm/r.
