.... The surface finish (roughness average, or R a ) on ground surfaces is typically in the range of 0.2 to 1 μm, whereas lapped and polished surfaces can have R a values of less than 0.05 μm. The material removal rates in lapping and polishing are usually an order of magnitude less than in grinding...

... and noncontact techniques, and the focus-follow method. Examples of different types of parameters obtained and how they are applied can best be described by discussing the various types of surfaces generated by finishing methods. The surfaces include ground, turned, and milled machined surfaces; surfaces...
