This post is about a cute little steel part (yes, steel can be cute) that started as a quick brainstorming session in engineering and resulted in a cool finished product for a Saskachewan electronics manufacturer. Even the smallest job at Lean Machine can involve all of management, engineering, administration, and of course our machining department. There are some pretty neat circular machining marks left on the part due to a unique machining method that we will explain below.
Below is the difference between traditional machining vs high speed. The idea is to take smaller (thinner) cuts at a faster rate. We try to achieve a cut with the entire diameter and height of the cutter engaged in order to spread the chip load over the whole tool (instead of just the leading edge). High speed machining also gets super technical by trying to match your cutting frequency with the resonant frequency of the machine but we will leave the explanation of that for another post.
