摘　　要：为了在硬质合金材料上得到不同微凹槽织构尺寸的加工参数,采用Nd∶YAG激光微加工系统进行微凹槽造型。利用单因素分析法分析了泵浦电流和扫描速度对微凹槽参数的影响。通过WYKO-NT1-100三维形貌分析仪研究了试样的表面织构形貌。结果表明:泵浦电流对微凹槽织构的宽度和深度影响都很大,而扫描速度主要影响微凹槽的深度及底部质量。当扫描速度为8 mm/s时,微凹槽的深度最大,底部质量最好。To obt ain the process parameters for micro-groove texture with different sizes on the surface of cemented carbide, the micro-groove modelling was carried out by using Nd∶YAG laser micro-processing system. The effects of pumping current and scanning speed on the micro groove parameters were analyzed by single factor analytic approach. The surface texture morphology of the sample was researched by WYKO-NT1-100 3D surface profile. The results show that pumping current has a great influence on the width and depth of the micro-groove texture. But the scanning speed only affects the depth and the bottom quality of the micro-groove texture. The depth of micro-groove is the largest, and the bottom quality is the best,when the scanning speed is 8 mm/s.
