摘要
本文基于MATLAB软件对铰刀进行了数字化建模,对周刃和端刃两部分进行分析,提出了刀具数学建模的通用步骤。重点说明了确定砂轮初始磨削位姿的关键步骤,并对铰刀的螺旋槽、周刃后角、锥倒角及其两后角进行了推算,得出了三者的数学模型,利用UG软件完成铰刀的建模。通过对比UG软件所得模型和NUMROTO仿真模型,验证了铰刀建模的精确性。
In this paper,the digital modeling of reamer is carried out based on MATLAB.The modeling of reamer is divided into two parts:peripheral cutting edge and end cutting edge.The general steps of mathematical modeling of reamer are putforward.The key step to determine the initial grinding pose of the grinding wheel is emphatically explained.The spiral groove,back angle of cutting edge,taper chamfering and the two back angles of reamer are calculated,and the mathematical models are obtained,and the reamer is modeled by UG.The accuracy of reamer modeling is verified by comparing UG modeling model with NUMROTO simulation model.
