一、优化数学模型的建立在进行切削用量优化工作中,很重要的一环,就是建立优化数学模型——反映各主要因素之间内在联系的一种数学形态。具体来说,即把工艺指标(目标函数)与切削用量之间的关系描绘成一个数学规划问题。在满足规定的条件下(约束条件),求出切削用量,使其目标函数达到最小值(或最大值)。 1.目标函数切削用量优化的目标函数,通常是指成本(或利润),因为它是工艺能力、管理水平和市场经济信息的综合,集中反映了该工艺过程经济效益的高低。当然,在某些情况下,也不排除
First, the establishment of mathematical model optimization Cutting optimization in the amount of work, a very important part is to establish mathematical model optimization - reflects the inherent relationship between the major factors of a mathematical morphology. Specifically, the relationship between the process indicator (objective function) and the amount of cutting is delineated as a mathematical programming problem. In the conditions to meet the requirements (constraints), find the cutting amount, so that the objective function to achieve the minimum (or maximum). 1. Objective function The optimization objective function of cutting dosage usually refers to the cost (or profit) because it is a combination of process capability, management level and market economy information, and it reflects the economic benefits of the process. Of course, in some cases, it does not rule out
