Software for a Computer Numerical Control System Designed for Adaptive Control Research
The paper starts by briefly outlining the overall system which comprises a commercial turret lathe which has been fitted with a multi component precision force transducer and tool wear measurement facilities etc. in such a way that it could be used in a normal commercial workshop. The machine is controlled by a 16-bit word length mini computer.
The method of presenting Adaptive Control information in a Part Programme is indicated and the bulk of the paper is then devoted to explaining how the software works. The routines to provide Adaptive Control fit into the overall scheme with virtually no alteration to the routines for conventional N.C. since this was part of the original design intention. Likewise, the Adaptive Control routines themselves are largely self-contained and can be modified in the light of experience without affecting the rest of the system. Finally, programme storage requirements and measured running times are given.
