Introduction to Machining: Milling Machine
•Before doing precise work on a milling machine, one must locate the edges of a part accurately. An edgefinder is designed to help you do this. •An edgefinder is composed of two concentric cylinders, spring loaded together. To use it, offset the two halves slightly so that there is a wobble as it spins. Then, move the part into the tool slowly.

How to prepare a technical drawing for CNC machining | Hubs
Introduction. Modern CNC machining systems can interpret the geometry of a part directly from the 3D CAD file. Technical drawings are not necessary to request a quote, but they are still very important and widely used in the industry, as they improve the communication of technical requirements between the designer/engineer and the machinist.. In this article, we will examine when and why ...
