摘要
介绍了美国ＰＭＣ公司制造的４７１型套管车丝机的控制系统，该系统以ＧＥＦＡＮＵＣ公司Ｏ—ＴＣ系列的ＣＮＣ为核心，通过进给伺服驱动系统和可编程机器控制器分别实现系统中的数字控制和顺序控制，通过安装的三种用户应用程序，加工程序、屏幕程序、ＰＭＣ梯形图程序，可在ＣＲＴ屏幕上观察到实时在线运行的情况，得到系统的诊断和报警信息，进而调整一系列的加工参数，从而大大加强了人机交流，更加有利于车丝机的正常运行。
The
control system of model 471 Casing Threader produced by PMC U.S.A. is introduced.
On the basis of CNC of O-TC series of GE FANUC corp., the control system realizes
the digital control and sequence control of the system separately through feeding servo
driving system and programmable controller. It can observe the real time inline
operation on the CRT screen and obtain system diagnosis and alarming information,
adjust a series of processing parameter and greatly increase man-machine conversation
as well as guarantee normal operation of the threader by installed three custom
application program , processing program, screen program, and PMC ladder diagram
program.
