Proposed in this paper an approach that the hidden curve removal algorithm is used to determine the 5 axis millable areas of interference free, which reduces the accessibility problem of 5 axis milling using a flat end tool to a 3 axis accessibility problem based on the Gaussian mapping. That is , using the M S mapping of a point q above surface S(u,v) and of constraining surfaces K(s,t), the surface S(u,v) regions that are hidden by constraining surfaces K(s,t) can be computed in the orthogonal space...

Proposed in this paper an approach that the hidden curve removal algorithm is used to determine the 5 axis millable areas of interference free, which reduces the accessibility problem of 5 axis milling using a flat end tool to a 3 axis accessibility problem based on the Gaussian mapping. That is , using the M S mapping of a point q above surface S(u,v) and of constraining surfaces K(s,t), the surface S(u,v) regions that are hidden by constraining surfaces K(s,t) can be computed in the orthogonal space D, then the domain of the surfaces S(u,v) that can be milled using 5 axis flat end tool without interference to constraining surface K(s,t) can be calculated by trimming away the hidden regions

提出了一种用隐藏曲线消除算法来确定5轴NC加工无干涉可加工性区域的方法.该方法基于高斯映射理论,将5轴铣削的可加工性区域变换成3轴铣削的可加工性区域,也就是,首先应用MS映射对加工曲面S(u,v)和约束表面K(s,t)进行数值计算,然后在正交子空间中采用隐藏曲线消除算法,将加工曲面的隐藏区域裁剪掉,则剩余部分能用平底刀在没有被约束表面干涉的情况下进行5轴NC加工.

Based on the idea of quantitative invisibility and the use of critical points, this paper propose a new hidden curve removal algorithm, which is used to decide what (accessible) portion of the model using 3-axis NC milling and a given tool directional orientation, and to avoid correspondent cutter interference in NC milling. This will offer a new way for the detection of cutter interference in NC machining of sculptured surfaces.

基于非可见性数和关键点的概念,提出了一种新的隐藏曲线的消除算法,并应用该算法来确定三轴数控铣削的可加工性区域,从而可避免相应的刀具干涉,为数控加工中的干涉检查及消除提供一种新的途径。
