| 摘 要： | 采用PCD刀具对C/SiC复合材料螺旋铣削与钻削制孔的制孔效果进行了对比研究。在同等加工效率条件下测量了两种制孔方法产生的切削力及切削热,并观察制孔质量。试验结果表明:螺旋铣孔产生的轴向力小于钻孔,约为钻孔的56.9%;孔壁粗糙度及孔径差均小于钻削;钻孔产生的切削热少于螺旋铣削制孔,约占螺旋铣的58.7%,但螺旋铣产生的切削热对材料及刀具的影响小。

| Abstract: | This artical carried out a comparative study between helical milling and drilling of C/SiC composite ma- terials. The cutting force,cutting temperature and hole quality of helical milling and drilling were measured under the same working efficiency. The results indicate that the axial force of PCD helical milling is less than PCD drilling and ocuppies nearly 56.9% of PCD drilling. The hole roughness and tolerance of helical milling are less than drilling. The cutting temperature of PCD drilling is less than helical milling and ccupies 58.7% of helical milling. In addition, the cutting heat of helical milling has a small influence on C/SiC composite materials and PCD tools. |
