本文报道了在研究高铝/刚玉颗粒复合材料可加工性的研究中获得的一些结果。刚玉分散体含量在0%到7%之间。通过在常规车床上车削试样进行标准加工试验。输入参数为切削速度、进给速度和切削深度。通过安装高速钢刀具的测功机测量三个垂直方向（即切向力、轴向力和径向力）的切削力。

THIS PAPER REPORTS SOME RESULTS OBTAINED IN AN INVESTIGATION TO STUDY THE MACHINABILITY OF HIDUMINIUM/CORUNDUM PARTICULATE COMPOSITES. THE CORUNDUM DISPERSOID CONTENT RANGED FROM 0% TO 7%. STANDARD MACHINING TESTS WERE CARRIED OUT BY TURNING THE SPECIMENS ON A CONVENTIONAL LATHE. THE INPUT PARAMETERS WERE CUTTING SPEED, FEEDRATE, AND DEPTH OF CUT. THE CUTTING FORCES IN THREE PERPENDICULAR DIRECTIONS (NAMELY, TANGENTIAL, AXIAL AND RADIAL FORCES) WERE MEASURED BY MEANS OF A DYNAMOMETER ON WHICH THE HIGH-SPEED-STEEL CUTTING TOOL WAS MOUNTED.
