Week 8 - Challenge 1 - Draft Analysis on a Fan Cover
1.TOOLING AXIS :
Toling axis is required in molding to open and close the core and cavity in molding.By visualising CLASS A surface we assume tooling axis where to appear but that is assumption made one or dummy axis for reference .To get tooling axis , we use bisecting method with dummy axis, it is one of the method to create it. Correct axis direction leads product designer leads to achieve simpler manufacture process and in less cost . Other wise it may leads to requirements for high accuracy and cost for manufacturing process. Follow the below picture:
2.DRAFT ANALYSIS:
we do this process to know wheter the designed part can get eject or remove easily after completeion of molding process. In this process , we have to meet standard draft angle during design and also after manufacture of product. Standard draft angle minimal is 3 degree and 0.5 to 1 degree is also there but achieve this number need high accuracy machinery process. Draft angle importance is very much in molding process , due to sharp edges on part may leads to break at certain apllied external load and it difficult to eject and it jams in core side of mold. If it meets the standard value it shows green and it's not and less than zero than shows blue and red respectively.Follow the below pictures :
a)Draft angle met to the standard value
b)Color differ with standard draft angle values folows the below picture:
