1- Squaring a Block on the Mill - What Does Squaring Mean?
|In the machine shop the word "square" means the same as perpendicular. Squaring means machining two surfaces perpendicular (at 90 degrees) to each other. Once two surfaces are machined perpendicular other square surfaces can be easily derived. The graphic on the right shows the four surfaces of a block of material, each of which is square to it's two adjoining surfaces.|
