CUSTOMER:
Major
Automotive Computer Manufacturer
PROBLEM:
To
automatically receive prefabricated computer frames directly from the die
casting line, drill and tap ten (10) separate through and blind metric holes, in
sizes from 19mm to 39mm, in both the vertical and horizontal planes.
SOLUTION:
Design
and fabricate a special linear machining system with twelve (12) work stations
for the purpose of producing finished machined computer housings at the rate of
10 per minute.
SPECIAL
CONSIDERATIONS:
 |
Provide
inspection stations to determine the presence and position of the die cast
computer frame, then not drill if improperly positioned or missing.
|
Drill
four (4) holes simultaneously in the frame's horizontal plane, index to the
next station and tap them simultaneously.
|
Index
to the next station and drill two (2) more holes simultaneously in the same
plane, index to the next station and tap them simultaneously.
|
Index
to the next station and gage.
|
Index
to the next station and rotate the frame.
|
Index
to the next station and drill four (4) more holes simultaneously in the
frame's vertical plane, index to the next station and tap them
simultaneously.
|
Index
to the next station and gage.
|
Index
to the next station and unload. |
