what is the dimension Chain? what is the closing link,increasing link and decreasing link?

Solutions

Expert Solution

The dimensional chain is close-sized group that consisting of interconnected dimensions during the machine assembling or parts machining .
Every size of dimensional chain is called link, including closing link and component link.
Closing link is the last link during machining or assembly; meanwhile, all the other links that affect closing links are named component link.
Component link includes increasing link and decreasing link. When the other condition keeps invariable, increasing link is one component link that will increase the closing link when its size increase.
Decreasing link is one component link that makes the size of closing link small when its size increases.
In the assembly relation of the machine, the assembly dimensional chain consisted of relevant parts size or mutual position relation .
The closing link of assembly dimensional chain is the requirement of assembly precision or technical; in other words, it can be depicted with size or mutual position relation of finally formed parts.
