Abstract: A lubricating coating composition and a compressor including a sliding member coated with the lubricating coating composition. The lubricating coating composition includes a thermosetting or thermoplastic polyimide-based resin as a binder, a solid lubricant, various solvents, and other additives at a controlled ratio. The compressor includes a first member including a first sliding surface and a second member moving relative to the first member including a second sliding surface. The lubricating coating composition is applied to the first sliding surface or the second sliding surface.

Abstract: A method of assessing three-dimensional volumetric errors of multiaxis machine tools in three-dimensional working space is disclosed. Each three-dimensional volumetric error component can be systematically measured and analyzed on the modeling of polynominal functions in accordance with the volumetric errors and the kinematic chain in accordence with the corresponding machine tool. The method inputs the measured radial data performed on the three orthogonal planes, analyzing the parametric errors such as positional, straightness, angular, squareness, and backlash errors. The positional error components along each of three orthogonal axes are modeled as a dimensionless polynominal function with corresponding positional error coefficients. The method also can assess dynamic performance of the machine tools such errors due to the servo gain mismatch. The method employs the kinematic ball bar to assess the volumetric errors.
