The process of micro-grinding on hard brittle glass is shown in this paper, micro-grinding equipments are designed by tools of electroplated diamond, fz(feed rate), ap (grinding depth), vg(Grinding speed) in micro-grinding brittle materials and their effects to surface quality have been discussed. It has been demonstrated that low surface roughness could be achieved by high vg and low fz. The roughness of Soda-lime glass accomplished by fz:100μm/s, ap:30μm, vg:120000rpm in the experiment is about 78nm.

Soda Lime Glass

In applications of brittle materials such as soda-lime glass and ceramics, they are usually subjected to a multi-axial stress state. Brittle materials with cracks or damage caused by foreign impacts are apt to fracture abruptly from cracks because of their low fracture toughness. Depending upon the crack pattern developed, the strength using a multi-axial stress state might be different from the one using a uniaxial stress. As a result, when a small size crack was introduced by Vicker's indentation, the residual strength using a biaxial stress state obtained by the ball-on-ring test was greater than that using a uniaxial stress by the 4-point bending test. In the case of the specimens cracked by a spherical impact, there was overall decrease in the bending strength with increasing an impact velocity.

This paper presents a micro-grinding experiment on soda-lime glass to study the surface quality effective factors during micro grinding on hard brittle materials. The process of micro-grinding on soda-lime glass is showed in this paper and micro-grinding equipments are designed, fz(feed rate), ap (grinding depth), vg(Grinding speed) in micro-grinding brittle materials and their effects to surface quality have been discussed by experiments which were carried out on a desktop micro machine developed by NEU. Results proved that fz is the most important factor to the surface quality, and low surface roughness could be achieved by high vg and low fz in micro-grinding soda-lime glass.

Abstract Micro machining of conducting and non-conducting materials with high accuracy has great demand in industries especially in machining of ceramic, brittle materials. Abrasive Jet Machining (AJM) has shown tremendous application especially in machining of hard and brittle materials. In the present paper drilling of soda lime glass has been carried out to determine the machinability under different controlling parameters. A set of L9 series experiments were carried out by varying process parameters such as Stand Off Distance (SOD), Silicon carbide abrasive particles mesh sizes and jet pressure. Material Removal Rate (MRR) and Radial Over Cut (ROC), were taken as the output responses and are optimised with multi objective optimisation.

Mechanical Machining

Micro mechanical machining, which is mechanical removal of material using miniature tools, is one of the fabrication methods in the micro realm that has recently attracted a great deal of attention. Micro machining has the advantage of being able to machine complex shapes from brittle materials. The most challenging problem in the micro mechanical machining of brittle materials is the fabrication of fracture-free surfaces. To avoid brittle fractures, a thorough investigation is required to find the machining parameters in the ductile cutting regime, which is characterized by plastic deformation of material when the chip thickness is smaller than a critical value. In this study, the cutting forces and surface characteristics of soda-lime glass are examined. Conical scratch tests are performed to identify the critical chip thickness, and the cutting forces in the ductile regime are modeled. In addition, torus end milling of glass is performed to examine the effects of feed rates, and spindle speeds, and to investigate tool wear.
