金刚石圆锯片锯解花岗石切削力及参数优化的实验研究

基于金刚石圆锯片锯解花岗石的切削力正交实验研究,对切削速度、进给速度和背吃刀量三因素影响切削力的显著性进行极差分析,得出切削力Fx、Fy、Fz随切削速度的增大而减小,随进给速度和背吃刀量的增大而增大的变化趋势。通过回归分析建立切削力数学模型并进行量化分析,得出切削速度对切削力Fx的影响要比对切削力Fy和Fz大、背吃刀量对切削力Fz的影响要比对切削力Fx和Fy大的结论,并以材料去除率和切削力为评价指标对工艺参数进行优化,得到用于生产加工的最佳工艺参数组合。

Experimental Study on Cutting Force and Parameter Optimization of Sawing Granite with Diamond Circular Saw

Based on the orthogonal experiment study of sawing granite with diamond circular saw, Through the range analysis, the significance of cutting speed, feed rate and cutting depth affecting cutting force was studied. Then come to the result that cutting force decreases with the increase of cutting speed, and increases with the increase of the feed rate and depth of cut. Through the mathematical models of cutting force established by regression analysis,the quantitative relationship between cutting force and three factors were studied. Then concluded that the effect of cutting speed on cutting force Fx is larger than cutting force Fy and Fz.And the effect of cutting depth on cutting force Fz is larger than cutting force Fx and Fy. The optimum parameters that have guidance function for production have been obtained by optimized parameters taking into account the machining efficiency and cutting force.
