TOP-MOPPP: Performing Machine Shop Operations

REV:04/10/08

SCOPE: This procedure covers the performance of individual operations within the Machining Department as well as the associated runtime quality control. "Operations" include machining, grinding, welding, stamping, cleaning, and so forth.

STEP WHO WHEN INFO TO USE WHAT TO DO RESULTS
1

Machining Supervisor

As need to assign operator(s) to a job

Machining Schedule; Production Floor Traveler; rest of job packet; own judgment

Determine what tasks need to be accomplished and what resources are available; confirm which machines are to be used for routed tasks and which operators are to be assigned (be sure that operator expertise has been established per TOP-TRECS); notify each operator which machine(s) he/she is to operate and which operation is to be performed (typically via Daily Assignment Sheet); be sure each team member has the appropriate Production Floor Traveler, tools, fixtures and materials; answer questions and solve problems

Operations assigned

2a

 

Operator*

 

Upon receiving assignment to perform operation

Machining Supervisor's verbal instructions; Production Floor Traveler; print and rest of job packet for machining (see TOP-MORDR)

Verify that Production Floor Traveler packet is complete and matches assignment; if for any reason you do not believe you are qualified for the assignment, notify Leadman; coordinate with Material Handler  for material to be delivered to work area; if needed, coordinate with Programmer for NC program to be downloaded to machine; verify that kit is correct and complete; verify that machine is operational.

Operation initiated by Operator

2b

Production Welder

Upon receiving parts and set-up to perform welding

Production Floor Traveler; parts; print; gauges; own knowledge

Verify that print and part match; that the Production Floor Traveler is in good order and that the machining has been properly completed; Examine part against print per print. Assure air/gas mixture meets welding and customer welding specifications; Use gauges and/or measuring equipment per TOP-MSURE and TOP-CALIB) to verify parts are being assembled to print; coordinate with Machining Manager to resolve any problem, bringing Machining Supervisor or Manager in as deemed appropriate; All completed parts are recorded in the Assembly Process Log for traceability of welded components. Any nonconforming or questionable parts produced shall be turned over to The QC Inspector with Discrepancy Report at the end of each shift. 

Verifications completed; Discrepancy Report of nonconforming or questionable parts turned in; completed parts recorded in Assembly Process Log

Material Handler

As jobs require material (typically forgings)

Machining Supervisor's verbal instructions; Production Floor Traveler; work orders from Shipping; container tags

Transfer forgings or other materials from storage to  work area; verify that container tags are correct; as operation progresses, keep materials supplied

Materials in place for operation

4

Programmer

As jobs require program download

Machining Supervisor's verbal orders; schedule

Verify program matches information on schedule and is correct for the machine to receive program; download to machine

Program in place for machining

5

Operator*

Upon setting up a machining operation

 

 

Production Floor Traveler; print and rest of job packet

Read operation instructions, Production Floor Traveler; review any setup photos; verify that heat code on material tag matches heat code on Production Floor Traveler; set up the machine; if an NC program is involved, verify that the program and revision match hard copy in job packet; run test part(s), check for correctness (see TOP-MSURE and TOP-CALIB) and make any necessary adjustments; If any raw material is found to be out of specifications, notify the Manager for disposition and to assess the need for a CAR initiation (See TOP-CARRR) when first correct part is produced, document dimensions on Inspection Records; take part with Production Floor Traveler and have QC Inspector verify and document all dimensions being machined; may have to perform this step multiple times to achieve buy-off); involve Machining Supervisor as deem appropriate or as appropriate by Production Floor Traveler; turn all scrap or questionable parts over to QC Inspector with discrepancy report at the end of each shift

Job set up; first correct part produced and recorded on Inspection Records;  nonconforming parts to QC Inspector

6

Operator and QC Inspector

Upon receiving parts for inspection

Inspection Order; Inspection Records; Production Floor Traveler; part; print; work order or purchase order; rest of job packet; own knowledge

Verify that Inspection Order, print and part match; verify that Production Floor Traveler packet is in good order and that the operator has properly completed his/her section of the Inspection Records; select measuring equipment per TOP-MSURE and TOP-CALIB; examine part against print per Inspection Order; verify that part meets specification and that operator's measurements (and, for welding, gage settings) are correct; coordinate with Machine Operator to resolve any problem, bringing Machining Supervisor or Manager in as deemed appropriate; upon first-part buy-off,  record results in Inspection Records then return documents to Machine Operator; for nonconforming parts produced subsequent to first part buy-off, Scan off job in M2M.

Parts inspected and discrepancies resolved; Inspection Records maintained; Discrepancy Reports produced as necessary

7

Operator*

As run operation

Inspection Order, Production Floor Traveler; print and rest of job packet for operation

Keep equipment and work area safe and clean; immediately report any machine or welding equipment malfunctions to Machining Manager, Machining Supervisor, or Maintenance Worker; produce parts per Production Floor Traveler; ink stamping of operator ID is required; use personal "logo" stamp (per TOP-STAMP); keep all parts containers and loose parts tagged (be sure the container you are working from, and to, has a QC tag on it; if the containers do not come out even, create or destroy the extra QC tags); perform quality control as specified in Inspection Order; during the processing of any Job Order requiring assembly, exercise extreme caution to assure assemblies are free of any debris or foreign objects as they are being closed or sealed: scan all time spent and part quantity machined into M2M; present any suggestions for improvement of the operation to Machining Manager or Machining Supervisor or Programmer (also remember the TOP-IDEAS!)

Machining, welding and other operations conducted in safe, controlled manner; Inspection Records maintained; ideas for improvement brought forward; data scanned in M2M

8

Machining Supervisor or Machining  Manager

As deemed appropriate during course of job

Own judgment; any documentation deemed appropriate

Observe running of operation; verify that documents are correct and that part is being run per plan; verify that Inspection Records are being maintained; review with the Operator and possibly other team members how the operation could be improved.

Machining Supervisor or Machining Manager review of process and opportunities for improvement
