Grinding (abrasive cutting) - Wikipedia

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).

6 steps to successful brazing - The Fabricator

First, the heating process: In brazing, apply heat broadly to the base metals. If you're brazing a small assembly, you may heat the entire assembly to the flow point of the brazing filler metal. If you're brazing a large assembly, heat a broad area around the joint. A hand-held torch most commonly is used to braze a single assembly.

This is achieved with a wheel and disc that produce incredibly high speeds that grind against the material and create powerful displays of friction. This friction is what causes the particles in the material to become activated with incredible amounts …

Guide to Manufacturing Processes for Plastics

Some manufacturing processes have high front costs for tooling and setup, but produce parts that are inexpensive on a per-part basis. In contrast, low volume manufacturing processes have low startup costs, but due to slower cycle times, less automation, and manual labor, cost per part remains constant or decreases only marginally when volume ...
