摘要:
针对通用CAD系统中没有轮胎文字符号专用设计工具、文字符号设计过程繁琐、设计效率低等问题,研究了文字符号程序化设计方法。分析其加工特点,提出最小工艺间距的概念,建立最小工艺间距计算公式;提出辅助测量圆的概念,以帮助设计人员直观判断刀具能否通过相邻文字符号;建立文字符号轮廓曲线特征提取算法;建立文字符号关系特征辨别算法,实现文字符号轮廓曲线程序化判定等操作。基于AutoCAD2014二次开发接口ObjectARX,开发相应的插件,实现文字符号从直线到圆弧、从圆弧到圆弧之间的程序化位置调整、间距调整和间隔调整。该方法提高了文字符号设计效率和设计质量。
Abstract:
As tire character symbol (CS) special design module in current Computer Aided System (CAD) has not been reported and a CS traditional design process is cumbersome in low design efficiency and poor design quality consistency,a programmatic design method is researched.The concept of the minimum process spacing (MPP) was proposed and a theory formula for calculating the MPP of different types of CSs was established.A concept of an auxiliary measuring circle (AMC) was proposed which can directly express whether a tool can pass through an adjacent CS or not.A contour curve feature extraction algorithm and a contour curve constitutive relationship automatic recognition algorithm were proposed to make a programmatic design possible.Based on the AutoCAD2014 API of ObjectARX,a corresponding function module was developed to make programmatic position adjustment,spacing adjustment and interval adjustment realized.It shows that the CS design efficiency and design quality can be greatly improved by employing this programmatic design method.
