Abstract

The purpose of this work is to investigate and develop optimization techniques
used for single pass turning operations on CNC machine lathes. The scope of this
work is limited to the Maximum Production Rate Criterion (Minimum Time
Criterion) for two machining variables, feed rate (f) and machining speed (v).
Further, a comparison of three methods of finding the optimum solution will be
made. The three methods used are:
1.A combined mathematical and graphical based optimisation technique
2. Real time simulated optimization on a CNC lathe
3. Neural networks to obtain optimum cutting conditions
The comparison of optimum time with limited constraints using mathematical
models and that of more optimised trends in CNC lathes give a better
understanding of the accuracy of modern machine tools and limitations of models
with limited constraints. Further, the neural network is also used as a decision
making tool in determining the optimum cutting conditions. It is hoped that the
neural network estimation of optimum cutting conditions are of reliable
quantitative accuracy.
