Home bore grinding cycle time calculation samac

A finish boring step is needed to meet tight tolerance requirements for roundness, straightness, position and surface finish. For example, Tegelman said fine boring is necessary whenever diameter tolerances are tighter than ±0.05 mm (±0.002"). The cutting edge of a finish bar is moved by a micrometric mechanism to adjust the bore diameter.

(ideal cycle time of 3 seconds x good count of 3,500) / planned production time of 18,000 seconds = 58.3% That's quite a difference! Although this is an acceptable calculation of OEE, it doesn't give us enough insight to know what we need to change if we want to improve it.


CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.

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.
