摘要

在航空结构件的加工中，除进给速度外，进给加速度和加加速度同样对加工效率具有重要影响。以S形试件S形缘条精加工为例，采用科德GNC61数控系统研究了进给速度、加速度及加加速度对加工时间的影响规律，分析了提高速度、加速度及加加速度对机床误差及S形试件加工误差可能产生的影响。结果表明，速度、加速度及加加速度的提高有效降低了S形缘条的加工时间，进给速度由1000mm/min提高到5000mm/min，加速度进一步由0.1m/s

提高到1.0m/s

，加速度建立时间进一步由200ms缩短到20ms，S形缘条的加工时间分别缩短24.20%、25.38%和41.84%。提高速度、加速度及加加速度造成的问题是指令频宽增宽及激励成分增多，使得机床跟随误差及联动轨迹误差的控制难度增大，并易于激起机床机械结构振动。

Abstract

In the processing of aerospace structural parts

in addition to the feed velocity

the feed acceleration and jerk also have an important inﬂuence on the processing time. Taking the fnishing process of the S–shaped fllet of the S–shaped test piece as an example

the inﬂuence of the feed velocity

acceleration and jerk on the processing time was studied using the Kede GNC61 CNC system. The possible effects of increasing velocity

acceleration and jerk on machine tool errors and S–shaped machining errors are analyzed. The results show that the increase of velocity

acceleration and jerk effectively reduces the processing time of S–shaped fllet. The feed velocity is increased from 1000mm/min to 5000mm/min

the acceleration is increased from 0.1m/s2 to 1.0m/s2

the acceleration establishment time is shortened from 200ms to 20ms

and the processing time of the S–shaped fllet is shortened by 24.20%

25.38% and 41.84%. The problems caused by increasing speed

acceleration and jerk are increased setpoints bandwidth and increased excitation components. This makes it more diffcult to control the tracking error and trajectory error of the machine tool

and it is easy to excite the vibration of the machine tool mechanical structure.
