The paper studies the influence of diamond grinding, lapping, and polishing on surface layer defectiveness Al2O3/TiC SiAlON ceramic samples. index ID, which is product defect density defective layer’s thickness (Rt), a method for its evaluation are proposed to quantify surfaces. Lapping reduces Rt parameter by 2.6–2.7 times when defects was decreased 2 times. After polishing, decreases 0.42 μm ...
In this study, special ceramic grinding plates impregnated with diamond grit and other abrasives, as well self-made lapping plates, were used to prepare the surface of single-crystal silicon carbide (SiC) wafers. This novel approach enhanced process reduced final chemical mechanical planarization (CMP) polishing time. Two different pads mixed abrasives prepared: one self-modified + SiC a binder...
This paper aims to improve a fine lapping process of hard disk drive (HDD) lapping machines by removing materials from each slider together with controlling the strip height (SH) variation to minimum value. The standard deviation is the key parameter to evaluate the strip height variation, hence it is minimized. In this paper, a design of experiment (DOE) with factorial analysis by twoway analy...
To date lapping as a finishing process of part surfaces lacks an underlying digital knowledge base. This is due to the complex interlinking numerous parameters that influence results machining. Starting from here paper argues improved planning and machining optimization by presenting new modelling algorithm software tool designed support for machine operators. The proposed computer programme en...
