Explain staking, and explain the effect of its use with large-diameter posts in large-diameter holes
What will be an ideal response?
Staking is used to attach a post inside a hole. It is done by heating the top of the post, often using ultrasonics, and then pressing the softened end of the post so that it spreads out and overlaps the part surrounding the post. On very large parts, the end of the entire post may be difficult to soften all at the same time, thus making staking difficult.
