05704-A-0145 四通道控制卡4 - 20mA输入

传统的CNC只提供直线和圆弧插补，对于非直线和圆弧曲线则采用直线和圆弧分段拟合的方法进行插补。这种方法在处理复杂曲线时会导致数据量大、精度差、进给速度不均、编程复杂等一系列问题，05704-A-0145必然对加工质量和加工成本造成较大的影响。许多人开始寻求一种能够对复杂的自由型曲线曲面进行直接插补的方法。国内外的学者对此进行了大量的深入研究，由此也产生了很多新的插补方法。05704-A-0145如A(AKIMA)样条曲线插补、 C(CUBIC)样条曲线插补、齐尔(Bezier)曲线插补、 PH(Pythagorean-Hodograph)曲线插补、B样条曲线插补等。由于B样条类曲线的诸多优点，尤其是在表示和设计自由型曲线曲面形状时显示出的强大功能，使得人们关于自由空间曲线曲面的直接插补算法的研究多集中在它身上。

Traditional CNC only provides line and arc interpolation, while for non line and arc curves, the method of line and arc segmented fitting is used for interpolation. This method can lead to a series of problems such as large data volume, poor accuracy, uneven feed speed, and complex programming when processing complex curves. 05704-A-0145 will inevitably have a significant impact on processing quality and cost. Many people are seeking a method that can directly interpolate complex free form curves and surfaces. Scholars at home and abroad have conducted extensive in-depth research on this, resulting in many new interpolation methods. 05704-A-0145, such as A (AKIMA) spline curve interpolation, C (CUBIC) spline curve interpolation, Bezier curve interpolation, PH (Python Hodograph) curve interpolation, B-spline curve interpolation, etc. Due to the many advantages of B-spline curves, especially their powerful capabilities in representing and designing the shape of free form curves and surfaces, research on direct interpolation algorithms for free space curves and surfaces has mostly focused on them.
