View Notes - Grinding and othe abrasive process-4M from INDUSTRIAL 110403426 at The Hashemite University. Chapter 9 Material-Removal Processes: Abrasive Machining and Finishing Operations GRINDING
Grinding, honing, and lapping are all common abrasive processes. These classes will explain all the abrasive processes used to shape and finish parts. The content is for individuals seeking to identify and understand all the various abrasive tools and machines used in the shop.
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.) .

The main uses of grinding and abrasive machining 1. To improve the surface finish of a part manufactured by other processes. Examples: (a)A steel injection molding die is machined by milling. The surface finish must be improved for better plastic flow, either by manual grinding using shaped grinding tools, or by electro-grinding.
Abrasive machining is a machining process where material is removed from a workpiece using a multitude of small abrasive particles. Common examples include grinding, honing, and polishing. Abrasive processes are usually expensive, but capable of tighter tolerances and better surface finish than other machining processes
Grinding, or abrasive machining, once performed on conventional milling machines, lathes and shapers, are now performed on various types of grinding machines. Grinding machines have advanced in design, construction, rigidity and application far more in the last decade than any other standard machine tool in the manufacturing industry.
Flap and Quick Change Discs for Effective Grinding, Cutting and Other Applications Metalworking abrasives from Weldcote include flap discs, quick change discs, Korner flap discs, resin fiber discs, flap wheels, cutting wheels, pipeline wheels and grinding wheels that are formulated for a wide variety of metals. Aluminum Grinding Reimagined
Most of these conventional processes can machine a large variety of materials; however, certain work materials don't provide acceptable machinability and therefore other material removal processes (such as abrasive cutting or NTM) are recommended in those cases.
Some of the operations are performed before starting the grinding process, and some are applied after the process proceeds. The operations that occur before the grinding process are called preparation and include ringing, mounting, and balancing. Other conditioning processes include cleaning-up, trueing, and dressing .
ABRASIVE GRINDING PROCESS DESCRIPTION. The machine parameters which affect the preparation of metallographic specimens include: grinding/polishing pressure, relative velocity distribution, and the direction of grinding/polishing. ... In other words, for brittle coatings the direction of the abrasive should be through the coating and into the ...
