Comparative assessment of two ceramic cutting tools on surface roughness in hard turning of AISI H11 steel: including 2D and 3D surface topography

Leakage directly affects the functional behavior of a product in engineering practice, and surface topography is one of the main factors in static seal to prevent leakage. This paper aims at monitoring the leakage in static sealing interface, using three-dimensional (3D) surface topography as an indicator. The 3D surface is measured by a high definition metrology (HDM) instrument that can generate millions of data points representing the entire surface. The monitoring approach proposes a series of novel surface leakage parameters including virtual gasket, contact area percentage (CAP), void volume (VV), and relative void volume (SWvoid) as indicators. An individual control chart is adopted to monitor the leakage surface of the successive machining process. Meantime, based on the Persson contact mechanics and percolation theory, the threshold of leakage parameter is found using finite element modeling (FEM). Experimental results indicate that the proposed monitoring method is valid to precontrol the machining process and prevent leakage occurring.

Elgiloy™ is a cobalt-based alloy with excellent physical and chemical performance, and is used widely in medical and industrial applications. The machining accuracy, surface topography, and surface damaged layer play an important role in the use of the alloy for specific applications. In this paper, an experimental study on the surface roughness of precision micromilling of Elgiloy is accomplished by using a super-fine-grained tungsten carbide milling cutter. The surface topography of the surface of the slots milled is achieved with different values of feed speed and axial depth of cut. Three-dimensional (3D) measurement results are considered to reflect the surface topography based on a comparison of the difference between two-dimensional (2D) and 3D surface roughness measurements. The arithmetic mean deviation of the slots’ 3D surface is achieved by using a white light interferometric profilometer. By using analysis of variance (ANOVA), the factors of feed speed, axial depth of cut, and their interaction are proven to be the most important factors relating to the magnitude of surface roughness.
