METHODS OF PREPARATION OF SURFACES AND APPLICATIONS THEREFOR

摘要

A method of machining a workpiece (14) using an active fluid and a tool (12) positioned substantially out of contact with a surface of said workpiece (14) which is to be machined utilises the combination of the shape of said tool (12) and its position relative to said surface cooperate to cause local enhancement of the activity of said active fluid, thereby locally enhancing the rate of removal of material from said surface.
