摘要:
为了准确判断和预测义齿铣削加工过程中刀具的磨损状况及磨损趋势,通过对义齿用预烧结氧化锆陶瓷进行系统的高速铣削加工试验,研究了切削参数及切削时间对刀具磨损的影响。按等时间间隔采集实测的刀具磨损数据,给出不同铣削速度下的刀具磨损曲线,基于灰色理论建立了刀具铣削磨损量的灰色预报模型(GM(1,1)),并对特定工况下的刀具磨损量及其寿命进行了预报,理论计算及试验验证表明预测值与实测值吻合较好,所建模型精度较高,能很好地满足铣削预烧结氧化锆陶瓷义齿时刀具寿命的预测要求,为合理使用、更换铣刀,保证义齿工件的加工质量提供了可靠依据。
Abstract:
In order to judge and predict the wear condition and wear trend of milling tool in denture machining process,a series of cutting experiments for pre-sintered zirconia is conducted to study the effect of the cutting parameters and cutting time on the tool wear in high-speed milling.A prediction model(GM(1,1))of cutter wear is introduced based on the theory of gray system after analyzing the tool wear data collected in the same time interval.The curves of the tool wear are provided at different cutter milling speeds.The cutter wearing capacity and lifetime can be forecasted based on this model,whose precision is verified after analyzing and comparing the measured value in an experiment.The prediction model can meet the demand of cutter forecast life used in high-speed milling of pre-sintered zirconia ceramic dentures and propose a way to change tools in proper time.All of these provide reliable basis to guarantee the machining quality of denture workpieces.
