优选法是根据生产和科研中的不同问题利用数学原理合理安排试验点、减少试验次数,以求准确而迅速地找到最佳生产点的一种科学方法。在金属切削加工中,处处存在着优选问题。举例来说,被加工零件的材质是我们以前没有碰到过的,怎么办?首先要考虑改变刀具角度,看看前角多大,主偏角多大,刃倾角多大,……刀具才能切割顺利,这其中就有个优选问题。优选法在金属切削领域中的应用,先是从切削用量(主轴转速,走刀量,吃刀深度)
The preferred method is based on different issues in production and scientific research using mathematical principles reasonably arranged test points, reduce the number of trials, in order to accurately and quickly find the best production point of a scientific method. In metal cutting, there are always preferred problems. For example, the material being machined parts we have not encountered before, how to do? The first thing to consider changing the angle of the tool to see how much the anterior horn, the main declination angle, how much blade angle, ... ... the cutting tool to smooth, This one has a problem of preference. Optimization method in the field of metal cutting applications, first from the cutting amount (spindle speed, take the amount of knife, eating depth)
