The Effects of ZrO2 or Tic on the Performance of the Alumina-Based Ceramic Cutting Tools
Two types of alumina-based cutting tools with compositions of 90 vol.% Al2O3+10 vol.% ZrO2 and 80 vol.% A12O3+20 vol.% TiC are produced by isostatic pressing and sintering technique. The effects of these additives on the mechanical properties and cutting performance of these materials are investigated. The tool life in both materials is examined under identical conditions on cutting a grey cast...
متن کاملResearch on Cutting Performance of Ceramic Cutting Tools in Milling High Density Fiberboard
The effect of cutting parameters and tool parameters on cutting forces and tool wear were investigated in high density fiberboard (HDF) peripheral up-milling using toughened ceramic cutting tools. The results showed that whether at low speed cutting or high speed cutting, the tangential forces Ft and normal forces Fr increased slowly with the increase of cutting length. The tangential forces Ft...
متن کاملSurface Characteristics and Biofilm Development on Selected Dental Ceramic Materials
BACKGROUND Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth. This study correlated surface roughness to biofilm development with four commercially available ceramic materials. METHODS Four ceramic materials (Vita Enamic®, Lava™ Ultimate, Vitablocs Mark II, and Wieland Reflex®) were pre...
متن کاملParametric influence on cutting parameters characteristics in precision machining of ceramic coating materials
PROF. MOHAMMED YUNUS, DR.J. FAZLUR RAHMAN Abstract— Ceramic coated components have the advantage features of both metal and ceramics, i.e. good toughness, high hardness and wear resistance. Despite their outstanding characteristics, ceramic materials are not used in many cases due to high cost of machining. A major draw back to engineering applications of ceramic is due to their brittleness and...
متن کاملA Comparative Study of Tool Life Between Ceramic and CBN Cutting Tools when Machining 52100 Steel and Optimization of Cutting Parameters
This paper describes a comparison of tool life between ceramics and cubic boron nitride (CBN) cutting tools when machining hardened steels using the Taguchi method. An orthogonal design, signal-to-noise ratio (S/N) and analysis of variance (ANOVA) were employed to determine the effective cutting parameters on the tool life. The results indicated that the V was found to be a dominant factor on t...
