Jun 06, 2019OEE definition. Overall Equipment Effectiveness (OEE) is the measure of an asset's performance compared to its full potential. It quantifies the utilization of manufacturing resources – specifically physical assets, time, and materials – during production to indicate any gaps between actual and ideal performance.. The term OEE was first used by Japanese maintenance consultant and

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.

Grinding Grinding is the most common form of abrasive machining. It is a material cutting process that engages an abrasive tool whose cutting elements are grains of abrasive material known as grit. These grits are characterized by sharp cutting points, high hot hardness, chemical stability and wear resistance.
