【摘要】：為研究單晶高溫合金的微銑削表面質(zhì)量,使用M.A.FORD雙刃端銑刀,刀刃直徑為0.8 mm,試驗材料為單晶高溫合金DD98,完成正交試驗研究.通過極差分析找出主軸轉(zhuǎn)速、進(jìn)給速度、銑削深度對微銑削表面質(zhì)量影響的主次因素,即主軸轉(zhuǎn)速的影響最大,銑削深度其次,進(jìn)給速度最小;采用統(tǒng)計學(xué)知識,獲得切削工藝參數(shù)的優(yōu)化組合,使表面粗糙度最小,即主軸轉(zhuǎn)速為n=3.6 kr/min,銑削深度為ap=5μm,進(jìn)給速度為v=100μm/s,對此優(yōu)化方案重復(fù)試驗,表面粗糙度值為951 nm.并對其切削機理和影響表面質(zhì)量及形貌的原因進(jìn)行深入的分析,對單晶高溫合金的微加工理論的機理揭示具有一定的指導(dǎo)意義.
[Abstract]:In order to study the micromilling surface quality of single crystal superalloy, M.A.FORD double-edged end milling cutter was used, the blade diameter was 0.8 mm, and the experimental material was single crystal superalloy DD98. The orthogonal experiment was carried out. Through the range analysis, we find out the main and secondary factors that affect the surface quality of micro-milling, that is, the spindle speed is the biggest, the milling depth is the second, and the feed speed is the least. The optimum combination of cutting process parameters is obtained and the surface roughness is minimized, that is, the spindle speed is 3.6 kr / min, the milling depth is ap=5 渭 m, and the feed speed is 100 渭 m / s. The surface roughness value of the optimized scheme is 951nm. The cutting mechanism and the reasons affecting the surface quality and morphology of single crystal superalloy are analyzed in depth, which is of certain guiding significance to reveal the mechanism of micromachining theory of single crystal superalloy.
