磨料有序化排布砂轮磨削 TC4温度实验研究

摘要

为了获得磨料有序化排布砂轮磨削 TC4的温度变化规律，使用电镀 CBN 砂轮对 TC4合金进行磨削实验。砂轮分别采用叶序、错位和无序3种不同的磨料排布方式。研究了工件表面平均温度与进给速度和磨削深度的关系，并对3种磨料排布方式的电镀 CBN 砂轮磨削工件时温度的变化形态进行对比。结果表明：在相同磨削条件下，磨料有序化排布能有效降低 TC4的磨削温度，使用叶序排布磨料砂轮能获得更低的工件表面温度。%In order to achieve the variation of grinding temperature during grinding TC4 with engineered grinding wheels . Phyllotactic , staggered and random arrangement way of electroplating CBN grinding wheels was used for grinding TC4 .Through the grinding experiment , the relationships of the feed velocity and grinding depth on the workpiece surface temperature and the comparison of grinding temperature with three kinds of engineered grinding wheels were studied . The test results revealed that the TC4 grinding temperature with engineered grinding wheels could be effectively reduced at the same grinding conditions , and lower surface temperature could be obtained with phyllotactic grinding wheel .
