METHOD AND APPARATUS FOR ASSESSING LUBRICITY OF CUTTING FLUIDS

摘要

The present subject matter relates to a method and an apparatus for assessing lubricity of a cutting fluid (2). The method includes cutting a work piece (1) immersed in the cutting fluid (2) with a cutting tool (3) to generate at least one new surface (4) on the work piece (1), and performing a friction test in-situ on the at least one new surface (4) immersed in the cutting fluid (2). The apparatus comprises a chamber (10) filled with the cutting fluid (2), a work piece (1) positioned in the chamber (10) and immersed in the cutting fluid (2), a cutting tool (3) to cut the work piece (1) and generate at least one new surface (4) on the work piece (1), and a friction measuring unit (5) to measure friction in-situ on the at least one new surface (4) immersed in the cutting fluid (2).
