众所周知,影响金属切削的因素很多,如切削用量、切削热、切削力和刀具的几何角度等。这一系列的参数在参加切削过程中是相互联系,相互制约的一个整体。所以,如果采用以往方法,先固定一个参数,优选另一个参数,反过来再固定另一个参数,优选其他参数,就把有机的整体分解成了个体,与实际可能存在一定的距离,为此,必须探讨一个多因素的试验方法。正交试验是一种科学地安排多因素试验方案和有效地分析试验结果的好方法。它能在多因素的条件下,以较少的试验次数,找到最佳配方或最佳操作条件,达到优选的目的。可以在不添设备,不增加投资
As we all know, there are many factors affecting the metal cutting, such as cutting the amount of cutting heat, cutting force and tool geometry and so on. This series of parameters to participate in the cutting process is interconnected, mutual restraint as a whole. Therefore, if the conventional method is used, firstly fixing one parameter, preferably another parameter, and then fixing another parameter, preferably other parameters, decomposes the organic whole into individuals and may have a certain distance from the actual. For this reason, A multi-factorial test must be explored. Orthogonal experiments are a good way to scientifically arrange multivariate test protocols and analyze test results effectively. It can under the conditions of many factors, with fewer trials to find the best formula or the best operating conditions, to achieve the preferred purpose. Can not add equipment, do not increase investment
