摘要：以Inconel 718镍基高温合金为研究对象,搭建试验平台,使用测力仪采集铣削过程的铣削力。采用自主研发的微结构涂层刀具和普通铣刀分别进行加工,设计合理的试验方案,对比两铣刀在相同工况下铣削镍基高温合金的铣削力和加工表面粗糙度,并探究微结构铣刀切削过程中不同铣削参数对切削力及加工表面粗糙度的影响规律。结果表明:与普通铣刀相比,自主研发的微结构铣刀切削力降低了9.66%~19.09%,而加工表面粗糙度降低了27.4%~47.03%,微结构铣刀具有更好的切削性能;在一定的切削速度范围内,切削力随着切削速度的增加先增加后降低,随着每齿进给量、切削深度和切削宽度的增加而增加。所建立的切削力多元回归预测模型具有较好的预测效果,总体误差小于20%;表面粗糙度随着切削速度的增加而降低,随着每齿进给量和切削深度的增加而增加,而随着切削宽度的变化,加工表面的粗糙度变化不明显。
Taking Inconel 718 nickel-based high-temperature alloy as the research object,a test platform was set up,and the milling force of the milling process was measured using a dynamometer.The self-developed micro-structured coated tool and ordinary milling tool were used for processing respectively.A reasonable test scheme was designed to compare the milling force and surface roughness of the two milling tools for milling nickel-based high-temperature alloy under the same working conditions.The influence of different milling parameters on the cutting force and surface roughness during the cutting process of the micro-structured milling tool was studied.The results show that the cutting force of the self-developed micro-structured milling tool is reduced by 9.66%to 19.09%and the machining surface roughness is reduced by 27.4%to 47.03%compared with the common milling tool,and the micro-structured milling tool has better cutting performance.The cutting force increases and then decreases with the increase of cutting speed in a certain range of cutting speed;it increases with the increase of feed rate per tooth,milling depth and milling width.The established multivariate regression prediction model of cutting force has a good prediction effect,and the overall error is less than 20%.The surface roughness decreases with the increase of cutting speed and increases with the increase of feed rate per tooth and cutting depth,while the machined surface roughness does not change significantly with the change of milling width.
