for the individual assignment i decided to do it while helping on of my student in his project.

Press-fit construction is also known as interference fit or friction fit

what is a interference fit ( press-fit ) ?

An interference fit, also known as a press fit or friction fit is a form of fastening between two tight fitting mating parts that produces a joint which is held together by friction after the parts are pushed together.

Tutorial i followed
