Free upper-disk rotational speed under loose abrasive grinding in conventional machines

Equations representing stable upper-disk rotational speed under loose abrasive grinding processes of flat optical elements, using conventional machines, are introduced. Solution was reached via two interpolations on a wide set of experimental data. Experimental upper-disk rotational speeds were interpolated by means of a power function on six enhanced variables. Enhanced variables are combinations of physical variables that interconnect independent machine and upper-disk three-dimensional experimental spaces. The exponents found were subsequently least-squares interpolated in upper-disk and machine experimental spaces. This process was performed twice to provide two perspectives on loose abrasive wear: one where machine variables lead both interpolations and upper-disk variables to play a secondary role through enhanced variables. On the second representation, disk and machine variables interchange roles.
