一、问题的提出笔者利用PC-1500袖珍计算机和CE-150绘图打印机,以国内外广泛使用的十字形钎头几何参数设计为题目,在新型十字(Ⅱ)型钎头的基础上,根据《DZ21-82》标准所规定的产品规格范围,总结了《成探》、《金龙》牌十字(Ⅱ)型钎头生产和使用的经验,设计了这个程序,作为计算机用于钎头几何参数辅助设计的初步尝试。本程序的目的在于: 1.解决实际工作中存在的重复设计问题,对φ32～65毫米范围内的十字形钎头主要参数的确定提供依据; 2.为钎头设计人员提供一个简便、迅速 First, the problem raised I use the PC-1500 Pocket PC and CE-150 graphics printer, widely used at home and abroad cruciform bit geometry design as the topic, based on the new cross (Ⅱ) type bit, based on the “ DZ21-82 ”standard product specifications range, summed up the“ exploration ”,“ Jinlong ”brand cross (Ⅱ) type bit production and use of experience, designed this program, as a drill bit geometry parameters of the computer aided The initial attempt to design. The purpose of this program is: 1. To solve the problem of repetitive design in practical work, to provide the basis for the determination of the main parameters of the cruciform drill head in the range of φ32 ~ 65 mm; 2. To provide a simple and quick
