TOP-PRINT: Forging/Machining Engineering Prints

Rev: 01/08/2021

Scope: This procedure covers development, approval and control of formal drawings, which affect the quality of product, such as forging, die and machine drawings. Simple concept sketches are not covered.

Procedure:

STEP	WHO	WHEN	INFO TO USE	WHAT TO DO
FOR INTERNAL PRINT CHANGES OR NEW DIE PRINTS START IN STEP 4
1	Anyone	Upon receiving Customer Print	Print received	Immediately pass print to Customer Service Representative
2	Customer Service Representative	Upon receiving Customer Print	Customer Print; Engineering file	If same revision as shown in computer, send to Engineering Assistant; if different revision than shown in M2M, place information in Print Review Spreadsheet; if an order was received with the print, see TOP-ORDER
3	Engineering Assistant	Print Review Spreadsheet is updated	Print Review Spreadsheet	Send out the Print Review Spreadsheet breakdown every Tuesday, Friday and any other day where an update is warranted.
4	Forging Engineer* or Manufacturing Engineer	Upon receiving notification of an update in Print Review Spreadsheet	Print Review Spreadsheet and any associated print; Engineering Files	Review indicated print revision to determine degree of change; if no previous Customer Print on file; describe degree of change on Print Review Spreadsheet; if change does not affect our process note in Print Review Spreadsheet; if change requires a modification to the dies or other tooling, indicate it on Print Review Spreadsheet to initiate quote process per TOP-QUOTE
5	Forging Engineer or Manufacturing Engineer	As needed to make formal or revise current drawing	Tooling Job Order; CAD File; possibly legacy hand drawing	Note: Any print update requires reviewing of all applicable prints. If existing drawing, use master CAD File from server if not an existing drawing; begin a new CAD File; make drawing per request, working out details internally and working with our customer to identify key characteristics of the forging (when not already known from history); discuss any opportunities for improvement or get any information needed from other team members; if modification to existing hand drawing, add new revision level and carefully track and initial all changes on revision block; for new drawing (or re-draw) establish and initial title block; if using CAD, plot/print drawing; submit drawing to another Forging Engineer for review .
6	Forging Engineer or Manufacturing Engineer	Within 48 hours of receipt of notification of a pending Print Review Spreadsheet entry	Print Review Spreadsheet breakdown email; Print Review Spreadsheet; storage folder for print reviews; associated print and/or Engineering Files	Review the necessary information to determine the required degree of change; if there will be no effect on our process and no changes are necessary update the Print Review Spreadsheet accordingly; if the print is better than the existing viewer print and no change is indicated per step 4, forward the print to the Engineering Assistant as a replacement print; for new prints where no previous print exist, new revisions of existing prints, or requested modifications to existing prints update the Print Review Spreadsheet; forward to the Engineering Assistant. (See Step 10) NOTE: For all prints placed in the Viewer Approved Folder; for indicated modifications to the dies/tooling or machine/forge process update the Print Review Spreadsheet to initiate the Quote process per TOP-QUOTE.
7	Forging Engineer (other than one in step 5)	As given drawing to review	Drawing provided by an Forging Engineer plus any source documents he/she can provide	Review for approval another Forging Engineer's drawing as appropriate; if disapprove, return to that Forging Engineer stating reservations either verbally or marked on drawing; if approved; electronically initial revision "Appvd" block of reviewed print; for new dies initial on "Chk'd" block of new print.
8	Forging Engineer	Upon receiving peer-approved drawing	Approved drawing	Verify that drawing is properly approved; determine whether customer or vendor print approval is required.
IF Customer Print APPROVAL NOT REQUIRED, GO TO STEP 15
9	Forging Engineer	Upon finishing new master drawing	Internally approved Forging Engineer's directions	The print gets emailed to Customer Service, to be send to the customer.
10	Customer Service	After receiving print from Forging Engineer	Updated Print Review Spreadsheet; M2M Customer Info	Send print to customer; file papers; place copy of cover letter in Print Follow-Up File.
11	Customer Service	Upon receiving customer response back	Response from customer (letter, print, etc.); Print Follow-Up File	E-mail customer's approval/ disapproval; file print or cover letter (if any).
12	Forging Engineer	Upon receiving customer response regarding print (dis)approval status	Customer response, including any print	Notify Customer Service if any customer change may have pricing implications; determine next step
13	Forging Engineer	IF PRINT IS DISAPPROVED BY CUSTOMER	Cover letter; print; Customer Print, sketch, sample or specifications	Determine degree of changes needed to print (go back to Step 4)
14	Forging Engineer	Customer approval of a drawing	Approved drawing	Prepare CAD and viewer files for production; place in the viewer approved folder and enter the information in the Print Naming Convention Spreadsheet; forward CAD files and approved drawings to Engineering Assistant.
15	Engineering Assistant	Upon receiving approved drawing and Viewer File	Approved drawing and Viewer File	Put drawing in Engineering Print Files; Viewer File and assign proper print status in viewer.
PRINT DISTRIBUTION
16	Engineering Assistant	Daily	Files in the Viewer Approved Folder	Review the Viewer Approved Folder; if new files are listed and there are corresponding prints in the Viewer Approved Folder rename the files in the Viewer Approved Folder; once the prints are renamed, follow the instructions listed for each print.
REDLINING PRINTS
17	User of controlled print copies	As need to "redline" copy	Print copies and other info	Pencil in notes or figures as needed on print, initialing and dating each such "redline" and, if redline changes any data originally on the print, include the reasoning and authority behind the change [note: redlines made prior to 4/93 did not require initialing and such]; if redline info needs to be added to print, notify Forging Engineer*.
PRINTING PRINTS
18	Anyone	As needed to print out approved prints from viewer	Print copies; stamps (located by the Engineering printer)	When a print is needed for a specific job, stamp it with the "Approved for" stamp and write in the job, date printed and printed by information; when a print is needed for any other reason, use the "Approved for 3 weeks from" stamp and write in the date printed and printed by information

* Forging Engineer is the engineer assigned to the customer

Note: "Customer" could be whoever is responsible to approve either a Forging Print or a Machining Print (i.e., customer could be our own Machining Department)
