  31. Cutting Speed Optimization

  32. Cost Optimization

  33. Product Design Considerations • Net-shape manufacturing, if possible • Tolerances specified for functional needs • Surface finish specified for functional needs • Sharp corners should be avoided • Avoid undercuts • Deep holes should be avoided • Use standard stock sizes as far as possible • Use standard tooling as far as possible • Use materials with good machinability • Minimum machining set-up • Parts should be able to withstand cutting force http://www.youtube.com/watch?v=QsmiIeAkE-o
