中心線平均粗さの多変量解析

There are a lot of theories of ground surface roughness which have been considered by theoretical analysis. However, with so many variables influencing surface finish there is very little published information to contribute simplicity for users in the quantitative selection of grinding parameters. This paper deals with a statistical model for the center-line-average roughness of the ground surface of the steel (S 45 C). A 3^5-1 fractional factorial design is used to study the influence of the five independent parameters that is, the grain size, the feed velocity of the table, spark-out, dressing sparkout and dressing speed on the surface roughness. Response surface contours are constructed and it is shown these may enable the user to choose the grinding conditions for a given surface roughness.
