1、 打孔机生产效能的提高 打孔机生产效能 提高 的数学研究 摘 要 针对“打孔机生产效能的 提高”问题，我们将给问题划分为：单钻头作业和双钻头作业两种情况。在针对以上两种情形做出以下操作： 一、对单钻头作业中的刀具转换方式问题，将刀具的转换方式类比成数学中的符号排列 组合 问题，由 Visual Basic 软件生成所有排列的组 合形式，再找出变换次数最少的那一组；对单钻头在打孔过程中的钻头行径 问题，利用计算机 JAVA 程序 计算出 多点间距离之和，由运行计算机程序计算出每类点的最短行径数，这样结合上面的最优刀具转换方式就可以使单钻头打孔效能提高 。 二、对双钻头可利用单钻头作业的工作原理，

2、将整张电路板分成某两个区域，是两个钻头各自在这两个区域内类似上述中的单刀作业原理独立作业即可。 关 键 词 ：单刀操作 ； 双刀操作 ； 绝对路径 ； 转义字符 ； 排列与组合 打孔机生产效能的提高 PUNCHING MACHINE PRODUCTION CFFICIENCY TO IMPROVE MATH STUDY ABSTRACT Aiming at the problem of the punching machine production efficiency improvement , we will give problem is divided into: single bit

3、 assignments and double bit assignment two cases. On the above two kinds of situations to make the following operation: Tool conversion problem single bit in homework, transform tool way analogy permutation and combination of symbols into a mathematical problem, by the combined form of Visual Basic

4、software to generate all arrangement and to find the minimum transformation number of the group； Of single bit in the process of drilling bit behavior problems, using the computer JAVA programs to calculate the sum of the distance between the more points, the number of shortest ACTS in each point is

5、 calculate by running a computer program , such optimal tool transformation combined with the above way can make single bit drilling efficiency improved. For the working principle of the double drill can use a single bit assignments will be the whole circuit is divided into two regions, two drill respectively in the two areas is similar to the single pole assignment principle of independent operation. Key words: Single pole operation； Double pole operation； Absolute path； Escape character； Arrangement and Combination
