Micro-Computer Control of an Electrochemical Machine

Chapter

Summary

Interfaces have been built so that a 10 000 A Anocut electrochemical machine can be controlled by a Commodore PET micro-computer. The computer directly reads ram position, machining current and electrolyte flow rate. It controls feed motor on-off, rapid traverse on/off, ram direction, machining voltage and electrolyte flow.

The Computer can run a complete cycle of operations tor a particular part and will provide adaptive control if this strategy is written into the program. Some examples of experiments with different methods of adaptive control are given.
