For simple single value problems use derivatives and find the maxima/minima.
7.4.1 Example Problem
As with most engineering problems we want to get the highest return, with the minimum investment. In this case we want to minimize costs, while increasing cutting speeds.
EFFICIENCY will be the key term - it suggests that good quality parts are produced at reasonable cost.
Cost is a primarily affected by,
The production throughput is primarily affected by,
The factors that can be modified to optimize the process are,
We previously considered the log-log scale graph of Taylor's tool life equation, but we may also graph it normally to emphasize the effects.
There are two basic conditions to trade off,
A simplified treatment of the problem is given below for optimizing cost,
We can also look at optimizing production rates,
We can now put the two optimums in perspective,
