Last month’s newsletter discussed some of the issues specifying floor and wall radii. This month we are going to leave the topic of geometry and instead talk about material specs, sizes, and other material cost drivers. The ideal scenario for selecting a material for your parts – is to choose one that is the cheapest…
Last month's newsletter discussed the length to diameter ratio of inside corner radii. We are going to explore this general topic a little further in depth this month. It isn’t uncommon for engineers to put a radius both on the floor and wall intersection as well as the vertical walls (see fig A). With the…
One of the single biggest cost drivers for machined parts is the length of time it takes to machine it. The rigidity and strength of the actual cutting tools often determines how much time it takes. Very simply, the shorter a tool is, the faster it can feed, and the less the part will cost…
