... on a machining center. An orthogonal array and the signal-to-noise (S/N) ratio are employed to determinate the optimal polishing parameters, and analysis of variance (ANOVA) is used to identify the main parameters that affect the surface roughness of the N-BK7 optical glass. An air-driving FJP tool is newly...

... process. As evaluated from model assumption analysis, the model for the polymerized height does not have a constant error variance and is more likely to make a type I error. The remedial measure has to be performed for the departure from the ANOVA model. As the error terms are normally distributed...
