ABSTRACT
Both the production cost and time are considered as objective functions. The production cost per component for a machining operation is comprised of the sum of the costs for tooling, machining, tool change time, handling time, and quick return time, which is given below:

The total time required to machine a part is the sum of the times necessary for machining, tool changing, tool quick return, and workpiece handling.
