hari ni final exam first paper aku, walaupun dah hampir belasan thun ambik exam tapi tiap kali nak exam mesti jadi x tentu hala..huhu, dah la paper pukul 9 pagi, so means kena bgun awal la..
paper design for manufacturing and assembly, DFMA..quiet tough subject.xda la susah nak score tp it have tedious Assembly analysis, td memang x sempat nak hbskn..pastu soklan yg kira senang pn silap jawab.aku tawakal ja dgn apa yg aku dah usahakn td..100% my pire idea, xda nak bawa2 toyol dalam exam..haha
aku nak kongsi sikit la pasal pa yang aku faham kat subjek ni, subjek DFMA ni ada 2 bahagian DFM and DFA.
i. DFM is design for manufacturing process, it involve early selection of material and process before it subjected to production plant, we could interpret what type of possible material and process by doing observation into attribute of component to be manufactured. it is important to give the company economical process feature and favorable to environment factor..
ii. DFA us design for assembly, it involve design the product with the minimum part count and ensure the remanining part is easily being done, it aims is to reduce the assembly cost by part or component reduction. the analysis will be based on three DFA approach; Boothroyd-Dewhurst DFA method, Lucas-Hull or Hitachi AEM method..but most popular is Boothroyd-Dewhurst DFA which DFA analysis is based on manual handling and insertion of part..it give details of each part to be assembled with assumption of assembly according to handling and insertion difficluties..it will strive to enchance the design effeciency by minimise part count.
then..integration of DFMA is: DFA at early stage then proceed to DFM for selection of material and process
ok la.panjang jg aku explain kan..huhu,selagi aku masih ingat better aku kongsi sbb ntah bila lagi belajar subjek ni,tp for sure it will be important assets during work on future :)
next subjek 8 januari ni..paper Production Planning and Control, insyallah buat yang terbaik :)
