圆孔拉刀设计的CAD与计算机辅助绘图

本文着重阐述了运用计算机辅助设计(CAD)与绘图技术进行圆孔拉刀的设计,并成功地解决了齿升量排列和齿距(即容屑槽型)选择等拉刀设计的关键性问题.其中部分设计已达到了优化要求.拉刀工作图在绘图功能极强的AUTOCAD绘图软件包支撑下绘制.整个软件技巧性强,考虑问题全面,操作方便,大大提高了圆孔拉刀的设计效率与准确性.

COMPUTER-AID-DESIGN AND DRAWING IN ROUND BREACH DESIGN

With the technique of the computar aided design (CAD) and drawing applied to the design of the round breach, some key problems in breach design such as the determination of the rise per tooth and the pitch of teeth (namely the type of the chip flute) have been successfully solved.Some of the designs are optimized. The tool diagram is drawn by means of AUTOCAD drawing software package, which possesses a strong drawing function. The software is characterized by the use of many programming techniques, the comprehensive design and convenient operation. The application of this software has considerably shortened the design cycle of the round breach design and the accuracy is guaranteed as well.
