- In
Option B the holes are produced in the tabs by using two cores to introduce rough
undersized holes in the coupler. Using the cores will eliminate the rough machining
requirement for the holes.
Since the holes have a tight dimensional
requirement, the holes will still have to be finish reamed.
A comparative cost analysis showed that, for this
component at a production rate of 250,000/year, the cost of fabricating and placing the
cores in the mold was more expensive than the rough machining step.
Option B is not the right design choice. Go back to the Options
page. |
