三维复杂槽型铣刀片粘结破损实验与槽型优选的研究

针对哈尔滨理工大学开发的三维复杂槽型波形刃铣刀片和平前刀面铣刀片,通过对耐热钢的面铣加工进行刀片粘结破损实验及槽型优选研究。首先,进行铣刀片三维温度场有限元分析,预测出波形刃铣刀片的抗粘结破损性能优良;其次,通过对温度场的模糊综合评判,预测了波形刃铣刀片的优越性能;最后,通过对难加工材料3Cr-1Mo-1/4V钢的面铣加工的实验研究,揭示了刀具粘结破损的实质,建立了铣削温度与前刀面最大粘结破损深度之间的数学模型,分析了铣削温度对刀具粘结破损的影响规律,并证明了波形刃铣刀片切削性能的优越性。

Study on adhering disrepair experiments and grooves optimization of complex three-dimension groove milling inserts

Based on the experiments on milling the refractory steel with the flat rake milling insert and the waved-edge milling insert with complex 3D grooves which is developed by HarBin University of Science and Technology,we have study on adhering disrepair experiment and grooves optimization.We have finite element analysis of 3D temperature fields,and forecast that the anti-adhering disrepair capability of the waved-edge milling insert is choiceness.We have fuzzy synthetical judgement on 3D temperature fields,the...
