I was wondering if anyone would be willing to share a control plan and pfmea with an added operation of assembly on it? Even just the section added to theirs to use for reference to make my own.
Hey bfire85 or even DAN_M Either one of you yahoos got a starter template for this? or davehocum <<<you're a nerd. You usually have stuff like this
giantslayer We do not do assemblies in our plant. We typically have outside operations (grinding, annealing, plating, etc). and secondary operations (bending, machining, deburring, belt sanding, etc.).
I would assume that you have routing operations, correct? Based on the print, you have the features that are affected by the assembly operation that are critical areas to check. With that operation, you have a process in which you will develop your PFMEA, which then drives your control plan. Shouldn't be too much different that a non-assembly CP & FMEA.
Would be happy to help I do our PFMEA stuff at my company
-Get a copy of AS13004 "Process Failure Mode and Effects Analysis (PFMEA) and Control Plans" and study it well
-Using 13004 as a guide, develop a Process Flow Diagram (PFD). A PFD is a breakdown of of each step of each process. You will use this document as a guide to make the PFMEA.
For example....
OP010 is INCOMING MATERIAL__you would break down on the PFD as op010 into the steps of...010_01: Measure material dimensions per PO reqs... 010_02: verify material cert... 010_03: check hardness per PO reqs...
You would then use this breakdown to form the PFMEA. When you're doing OP010 on the PFMEA, you go in those 1,2,3 steps so someone who is reading the PFD & PFMEA side by side can truly see that one document is the input for the other
-Making the PFMEA for the assembly is no different....just methodically break out each assembly op's steps on the PFD then follow it through on the PFMEA
Protip: go to Rolls Royce supplier portal...you don't need credentials...theres a place you can navigate to where they show excellent examples of PFMEAs and have stuff they encourage you to steal & use
As far as sharing the actual document(s) themselves , I am sorry i can't do that. The documents are in a locked system that are all ITAR locked down by my IT Dept..here is something nonpropriatary i am working on though (screen grabs):
