TOP-MOPPP: Machining Department Operations

Rev: 02/16/2024

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.

Procedure:

STEP WHO WHEN INFO TO USE WHAT TO DO

1 Machining Department Supervisor As need to assign operator(s) to a job Machining Schedule; Production Floor Traveler; rest of MPS 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-TRAIN); notify each operator which machine(s) he/she is to operate and which operation is to be performed; be sure each team member has the appropriate Production Floor Traveler, tools, fixtures and materials; answer questions and solve problems

2a Operator* Upon receiving assignment to perform operation Machining Department Supervisor's verbal instructions; Production Floor Traveler; print and rest of MPS 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 Machining Department Leadman; coordinate with Machining Department Material Handler for material to be delivered to work area; if needed, coordinate with Machining Department Programmer for CNC Program to be downloaded to machine; verify that kit is correct and complete; verify that machine is operational.

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, assure air/gas mixture meets customer's 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 Superintendent to resolve any problem, bringing Machining Department Supervisor or Machining Superintendent in as deemed appropriate; all completed parts are recorded in the Assembly Process Log for traceability of welded components; turn any nonconforming or questionable parts produced over to the QC Inspector with Discrepancy Report at the end of each shift.

3 Machining Department Material Handler As jobs require material (typically forgings) Machining Department Supervisor's verbal instructions; Production Floor Traveler; container tags Transfer forgings or other materials from storage to work area; verify that container tags are correct; as operation progresses, keep materials supplied

4 Machining Department Programmer As jobs require program download Machining Department Supervisor's verbal orders; Schedule Verify program matches information on schedule and is correct for the machine to receive program; download to machine

5 Operator* Initially when setting up a machining operation Production Floor Traveler; print and rest of MPS Job Packet Validate all gages to be used on operation are available and ready.

Make sure all gages have calibration stickers and are within the calibration date prior to use.

Validate that the measuring verification log has been filled out, if not fill out and notify QC immediately.
6 Operator* Upon setting up a machining operation Production Floor Traveler; print and rest of MPS Job Packet Read operation instructions, Production Floor Traveler; review any setup photos; verify that heat code on material tags matches heat code on Production Floor Traveler; set up the machine; if a CNC Program is involved, verify that the program and revision match hard copy in MPS 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 Machining Superintendent 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 Department 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

7 Operator* Upon receiving parts for inspection Inspection Order; Inspection Records; Production Floor Traveler; part; print and rest of MPS 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 Operator to resolve any problem, bringing Machining Department Supervisor or Machining Superintendent 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.

8 Operator* As run operation Inspection Order, Production Floor Traveler; print and rest of MPS Job Packet for operation Keep equipment and work area safe and clean; immediately report any machine or welding equipment malfunctions to Machining Superintendent, Machining Department Supervisor, or Maintenance Man; 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 Superintendent or Machining Department Supervisor or Machining Department Programmer

9 Machining Department Supervisor or Machining Superintendent 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.

10 Operator* As discovers nonconforming parts Own judgment; any documentation deemed appropriate Fill out Discrepancy Report and take parts to QC Inspector per TOP-MOPQC.

11 Machining Department Material Handler As containers of machined parts are completed Production Floor Traveler; container tags Ensure that containers are properly tagged; forward containers to QC area until final buyoff is performed; confirm signed Production Floor Traveler is attached to container; mark all boxes with a green M; move container of parts to storage area; observe TOP-MORDR for warehousing and (if complete) transfer to Shipping; for partially-machined parts, ensure tags clearly indicate the stage of the parts' progress

12 Operator* As the end of job a is reached All documents and remaining materials About 2 hours before you expect the job to finish; notify the Machining Department Supervisor and the Machining Department Material Handler; when last part is complete, clean up tools and machine; return tools to crib as appropriate; complete job per TOP-MORDR; leave work area in a clean and safe condition; alert Machining Department Supervisor you are moving to next assignment; scan off job in M2M.

13 Operator* When machine is unable to operate properly for any reason Own observation Scan downtime in M2M; notify Machining Department Supervisor or Maintenance Man.

*"Operator" may refer to Machine Operator, Welder or other team position.
