【摘要】 本文提出了数控加工技术中双圆弧插补的一种新方法：公切点选取不是从几何出发而是从最省材料的物理角度来考虑，并直接首次给出了满足工程设计要求的计算公式而无需迭代，还首次给出了工程设计点的概念。更多还原

【Abstract】 This paper presents the concept of engineering design point in computer numerical control (CNC) technique. Then, in this paper, we give a new fixed method of common tangent point of biarc curve, i. e., the common tangent point is the engineering design point. Finally, we present the formulae that satlsfy the requirements in engineering design.更多还原
