To determine the grinding forces, a transient kinematic approach is developed. In this method, the individual grit interaction with the workpiece is extended to the whole cutting zone in the peripheral flank grinding operation. Hence a predictive model of cutting forces and surface roughness in micro grinding of titanium grade 5 is developed.

One such example is the Marposs T25, an off-the-shelf probe but one with 0.5 µm repeatability. In a common approach, the machine would probe a ground diameter and use that information to calculate the actual diameter of the grinding wheel, adjusting the appropriate axis position (generally X) going forward.

Micro electrochemical discharge machining (ECDM) is a well-known machining process that achieves 3D micro structures in glasstype material. However, a rough surface is the main disadvantage of this process. In the present work, a hybrid process of ECDM and micro grinding using polycrystalline diamond (PCD)tools is investigated. Micro structures in glass workpieces were …

Grain micro-fracture (microcrystalline splintering) – Grinding forces are sufficient to cause small scale grain fracture, resulting in continuous generation of sharp cutting points. This is often accompanied by steady-state grinding power. Grain micro-fracture is favorable for consistent, predictable grinding.

Micro-grinding is an important processing method in micro-manufacturing field. A series of micro-grinding experiments were done with several kinds of commonly used metal materials in the paper, and the influence of different grinding factors on the surface quality of the work-piece was discussed. The surface roughness and surface microstructure of each material were analyzed in micro-grinding.

An appropriate grinding speed is also important for achieving a stable and efficient micro drill-grinding force, but the micro drill-grinding speed does not have a strict correlation with the drill-grinding force F z and A z because of the very low micro drill-grinding speed (0.471–2.355 m/s) of single grit in the model of Fig. 3(c).

It is confirmed that the micro-form and the micro-profile errors reached 8.3 μm and 16.9 μm, respectively. The micro-form and the micro-profile accuracies were controlled within 4% through micro-grinding. Therefore, the micro-grinding can realize the precise micro-fabrication of large-depth micro-structures on hard and brittle materials. (1)

The bond is the substance that causes the abrasive grains to adhere to the wheel. Bonds can consist of different materials. Common materials include shellac, resinoids, rubber and glass or glass-ceramic. At Weiler Abrasives, our portable grinding wheels contain resinoid bonds. The bond on a grinding wheel may be either hard or soft.
