花岗石显微硬度与磨加工效率相关性的试验研究

Correlation of the Microhardness of Granite and the workable Efficiency of the Same

本文对10种花岗石分别进行钻进、磨削和锯切3种磨加工试验,分析了花岗石加权显微硬度和硬度的离散值与磨加工效率的相关性,提出了相应的复回归方程式,以此为基础结合实际生产,将花岗石可加工性分成三大类别。

In this paper the authors disscussed the correlation of the weighted microhard-ness of stone, the discrete value and the workable efficiency through the drilling, grinding andcutting test on 10 kinds of stone, and established the relative complex regression equation, andthen the classification of the stone machinabitity was made on the equation.
