SURFACE FINISH & GRINDING EFFICIENCY VARIABLES
SURFACE FINISH VARIABLES
Changes in any one of many factors can affect the surface finish generated by a product. The purpose of this
chart is to show the effect on surface finish by changes in single factors of product specifications. Arrows have
been used to signify the trend direction. The length of the arrows has no significance as the effect of each variable
factor will not be the same. The chart is meant to be general in nature and to show direction or trend.
