Concave vs. Convex: What's the Difference? - Writing Explained

Concave is an adjective that describes a surface that curves inward, or is thinner in the middle than on the edges. In ordinary usage, concave and convex are typically used when referring to glass surfaces, like the lenses of optical viewing equipment. The side mirror of a car has a concave surface. The inside surface of most eyeglasses is concave.

Introduction to Milling Tools and Their Application

Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the narrower the channel for chip evacuation.
