Statistical approach calculating ground surface .

Micro-grinding is a machining method to create submillimeter structures, and it can be applicable to various kinds of materials with a flexible forming ability. However, the micro tool may be easily bended by the grinding force, which results in relative low form accuracy and worse ground surface roughness. To solve these problems, ultrasonic assistance was applied to micro-grinding. This ...

GRINDING PARAMETERS CONVERSION .

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.

CHAPTER 4 GRINDING FORCE MEASUREMENT

grinding force from the power is found to be 20.8 N, considering the wheel velocity as 33.6 m/s. This is due to the fact that the leading edge of the wheel removes uniform portion of the material and the wheel is in full contact with the workpiece. The average of the net power consumed during the region B was used to calculate the tangential grinding force from the equation (3.1). The observed ...
