摘要
进行了精密铣削钛合金粗糙度试验研究,采用正交分析方法,分析切削三要素铣削速度、进给量、铣削深度对表面粗糙度的影响规律,试验采用直径为2mm的3刃铣刀进行铣削。试验结果表明:表面粗糙度影响顺序依次是进给量、切削速度、切削深度。进给量选为0.01-0.05mm/min时,表面粗糙度随进给量的增大而增大。铣削深度在60-150μm、铣削速度在18.84-47.10m/min试验范围内,最优铣削速度为37.68m/min。而铣削深度对钛合金表面粗糙度影响不大。
The surface roughness of the precision milling titanium alloy was studied in this essay. The effect factor of the three elements of milling--the milling speed, the feed rate and the milling depth, were analyzed by the orthogonal ana- lytic method . The diameter of 2mm milling cutter with the blade of 3mm was used in the cutting experiment. Experimental results show that the most influential factor to roughness is the feed rate, the second is the milling speed, and the last one is the milling depth. When the feed rate is between O. 01 mm/min -0.05mm/min, the roughness increased with the feed rate. When the milling depth is 60 - 150μm and milling speed is between 18.84 -47.10m/rain,the optimal feed rate is 37. 68m/min. But the milling depth has little effect on the titanium surface roughness.
