“…It is a special type of brittle solid material, which combines the polycrystalline properties of ceramics with the amorphous qualities of glass [6,7]. Glass-ceramics has excellent insulation, corrosion resistance, low high frequency dielectric loss, low expansion coefficient and easy peeling, which makes it widely used in the fields of biomedical, optoelectronic communications and aerospace [8]. However, due to the incomplete understanding of the processing mechanism, the improper selection of process parameters and processing tools will inevitably lead to poor surface quality and low processing efficiency.…”

Cutting force is one of the most important physical quantities in the cutting process. Cutting force directly determines the generation of cutting heat and affects tool wear and machined surface quality. In this work, based on the geometric analysis of the turning tool, the cutting edge was discretized, and the local parameters of each cutting edge were calculated.According to the formation and assumption of brittle material chips, considering the energy dissipation in the process of chip formation, the cutting force of each cutting edge element was calculated. Then, the theoretical model of three-dimensional turning force of glass-ceramics was established by adding the forces contributed by all cutting edge elements. The change of tool geometry angle can lead to the change of local cutting parameters at each point on the cutting edge, thereby affecting the variation of cutting force. In order to evaluate the cutting force model, the turning experiment of fluormica glass-ceramics was carried out, and the influence of tool geometry angles (normal rake angle γn, tool nose radius rε and tool cutting edge angle κr ) on the cutting force were discussed. The predicted results are in good agreement with the measured results. This model can provide theoretical guidance for the efficient turning strategy of glass-ceramics.

“…glass-ceramic can have higher hardness and mechanical strength by controlling the crystallization process [1,2]. Glassceramic is gradually replacing some traditional materials and widely used in chemical, aerospace, construction and other fields with good mechanical properties and mechanical properties [3,4]. Optical free-form surface is an optical surface with arbitrary complex surface shape, and its important feature is nonrotational symmetry [5].…”

Glass-ceramic is a typical hard and brittle material that is difficult to machine. In order to improve the surface quality of laser-assisted fast tool servo machining optical free-form surface of glass-ceramic, the effects of spindle speed, feed speed, piezoelectric frequency and laser power on the surface roughness were investigated. Firstly, the Taguchi method (TM) was used to establish the orthogonal experiment, and the contribution rate of each machining parameter to the surface roughness was obtained through variance and signal-to-noise ratio (S/N) analysis. The order of the influence degree of each parameter on the surface roughness is as follows: laser power> spindle speed> feed speed> piezoelectric frequency. The optimal machining parameter combinations obtained for the TM experiment are as follows: spindle speed 50rpm, feed speed 0.01mm/rev, piezoelectric frequency 8Hz, laser power 75W. The range of surface roughness reduction obtained by comparing laser-assisted machining (LAM) with pure fast tool servo (FTS) machining is 38.75%~58.77%. The Box-Behnken Design (BBD) in response surface methodology (RSM) was used to design experiments and a regression model for surface roughness was established through RSM. The deviation between the surface roughness predicted by the regression equation and the experimental value is less than ± 6%. The influence law of various machining parameters on surface roughness was studied through three-dimensional response surface. RSM optimized the minimum surface roughness with a desirability of 99.43%. The optimal combination of machining parameters optimized through RSM is as follows: spindle speed 53.71rpm, feed speed 0.02mm/rev, piezoelectric frequency 6.73Hz, laser power 72W. This paper is the first to combine LAM with FTS for machining optical free-form surface of glass-ceramic. This study provides a reference for laser-assisted fast tool servo machining and the research methods of surface quality.
