Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

High-efficiency milling is based on the "radial chip thinning" theory that's been around for a long time. The basic idea is to keep the tool cutting at an ideal chip load. To increase the metal removal rate, the stepover is substantially reduced from the typical 50% of tool diameter, but the feed rate is increased in order to maintain the ...

An abrasive is a material, often a mineral that is used to shape or finish a work piece through rubbing which leads to part of the work piece being worn away by friction.While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the Ceramics which are …
