RESULTS |
| 1 |
Machining Department Supervisor
Manager or Programmer |
Upon
receiving Engineering Change Notice, drawing
revision, specification, purchase order (PO) or other
information that might affect an
MPS |
Job Order,
written spec, print or advice from machinists or
others; own observations; MPSs |
Review new
information and MPS (if any) and identify any
questions which need to be resolved; work with any
team member, customer or supplier as appropriate to
resolve questions and reach agreement on what is
needed in the MPS(s); determine how well current MPSs
meet the needs identified; if any customer or
reference specifications (other than dimensional) are
involved notify QA Manager per TOP-TPSMM; ensure that
there is an Operation
and Inspection Order set up for each
machining operation, verify that all Inspection
Orders clearly specify "who",
"what", "how", "when",
and "how many" for each operation; verify
that all operational and inspection issues related to
handling storage, packaging, preservation and
delivery are covered. NOTE REGARDING WELDING
OPERATIONS; Welding is a "special" process
whereby the results of the operation cannot be fully
determined without destructive testing. For any
welding operation the MPS must be specific concerning
all details of the process (gage settings, amperage,
wire, etc.) and of the welder's qualifications
(team position). |
Clear,
agreed-to specifications and process plan; decision
regarding how MPSs should be changed (if at all); QA
Manager notified if change may be
needed |
| 2 |
Machining Department Clerk |
Upon
receiving new information from Supervisor, or
feedback from machine shop
personnel |
Marked up
MPS with redlined changes, or new
information |
Change MPS
on computer to reflect new info; be sure MPS revision
date is updated on computer; route to a second person
approved to create MPSs (Supervisor, Manager or
Programmer) for review and approval (both new and
updated MPSs get reviewed). |
Updated MPS
in data base; MPS change routed to
reviewer |
| 3 |
Machining Department Supervisor,
Manager or Programmer |
Within 1
week of receiving MPS change for
review |
MPS; revised
drawing, customer specification or other data deemed
needed |
Review MPS
versus specs and other documentation; for welding
operations see note in step 1; if any problems found
or potential need seen notify Engineer or Programmer,
so note on MPS; if okay, approve
MPS. |
MPS routed
to Clerk, either approved or disapproved, with any
problems or possible need for further consideration
noted |

Machining Department Clerk |
Upon
receiving revised MPS |
MPS |
If problems
noted on MPS, return to step 1 (or, if minor, step
2); if approved, send MPS to Programmer if NC program
changes are potentially required. |
After MPS
update approved, MPS routed to Programmer if program
changes are possibly needed |
| 5 |
Programmer |
Upon receipt
of revised MPS |
MPS; input
from Leadman, Manager, or Engineer |
Change NC
programs as necessary per TOP-MORDR to reflect MPS
change. |
NC programs
updated to reflect relevant MPS
changes |
