Continuous and discrete statistical distributions: Probability density/mass function, cumulative distribution function and the central limit theorem
In real world, all variables are random and the randomness is modelled by statistical distributions. In this post, various type of statistical distributions for both continuous and discrete random variables are explained.
2D tolerance stack-up analysis with examples
Every part constituting an assembled product has tolerances assigned to the part’s features. These assigned tolerances cause variations on the key characteristics (KCs) of the assembled part. How can we know how much the variations on the KCs before manufacturing the parts?
Understanding fixturing constraints: locator, clamping, support and guide
Fixturing system has a very important role in assembly processes. Despite the complexity of fixturing systems, there are four main roles that fixturing systems should have. The four roles are locating, clamping, supporting and guiding parts during assembly processes.
Understanding fundamental assembly features: Mate and contact features
Assembly is the final step to make a product in its complete form. However, no matter how complex the geometry of a part is, the part’s assembly features are boiled down to two fundamental types: mate and contact features.
