非圆曲线在数控编程系统中的处理方法

Acceleration programming for minimizing residual vibration of rotary arms

论述了任意非圆曲线的数学表示及求值技术,并给出了该种曲线的双圆弧逼近算法。

A finite fourier series expression is used to shape the desired motion of a single-de-gree-of-freedom flexible arm.The residual response spectrum in desired regions can be greatly depressed by selecting the fourier coefficients.This depression is insensitive to modeling errors.The effectiveness of the presented approach can be seen from the response spectra of the system.
