摘要
为降低钻削过程中BTA单管钻头温升和磨损深度,建立钻头温度场导热离散化模型与Usui磨损模型,运用Deform-3D有限元软件模拟BTA单管钻温度及磨损深度变化规律,以进给量、钻头转速、环境温度为考察因素,以钻头温度和钻头磨损深度为考察指标,采用SPSS23.0软件设计三因素四水平L 16(43)正交试验法,并进行方差分析。结果表明:三种因素对加工过程中钻头温度及磨损深度的显著性次序依次为钻头转速、进给量、环境温度。
In order to reduce the temperature rise and wear depth of BTA single pipe bit during drilling,a bit temperature equivalent model and Usui wear model were established.The Deform-3D finite element software was used to simulate the temperature and wear depth variation of the BTA single-tube drill.This method takes feed rate,cutting speed,and ambient temperature as the investigation factors,and takes the bit temperature and bit wear depth as the investigation indicators.At the same time,SPSS23.0 software was used to design three-factor and four-level L 16(43)orthographic test and the analysis of variance was carried out.The result shows,the significant sequence of the three factors on the bit temperature and wear depth during the machining process is cutting speed,feed rate,and ambient temperature.
