摘要
针对具有平面复杂曲线的零件表面建立扫描的数学模型,保证扫描速度基本恒定,对实际生产有重要的意义。以盘形凸轮零件为例分析扫描外形轮廓时的运动关系,用折线代替曲线,将复杂的凸轮轮廓适当简化,建立运动参数间的数学关系,实现对凸轮工作表面扫描的速度基本不变。
The complex curve with a flat part of the mathematical model of the surface of the establishment of scans to ensure that the basic constant scanning speed of the actual production of important significance.To disc cam contour parts as an example of scanning when the relationship between the movement,with broken line instead of curves,to simplify the complex cam profile suitable to establish the mathematical relationship between the motion parameters to achieve the working surface of the cam speed of scanning remain basically unchanged.
