Grinding forces depend on the balance of stresses, as the abrasive grains shear the workpiece material. In metal cutting, there are three main zones of plastic shearing, all within the workpiece material. The principle of minimum energy states that the stress arrangement that requires minimum total energy is …

A method of dressing a threaded grinding wheel such that twisting of workpiece tooth flanks does not occur during grinding. The grinding wheel is preferably dressed with a circular arc hollow-crowned generating front with the generating front being described by a radius, Rb, and dressed into an axial plane of the grinding wheel. The workpiece is then relatively shifted across the grinding ...

osteosynthesis principles (MIPO) should be utilized in order to maintain correct length, axial alignment, and rotation of the limb • Depending on the bone quality, both locking and non-locking plates can be used, although locking plates have the biological advantage of not compressing the periosteum . 35

The basic principle of the QUBE grinding machine series is the vertical arrangement of components. The work piece headstock is always above, and the tools below. Like the ULTRA series, the QUBE can also perform internal or external grinding with corresponding axis arrangements. This provides the greatest possible efficiency in the smallest space.

Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).

Electrical discharge machining process works on the basic principle of spark generation and metal removed by spark erosion. EDM spark erosion is same as electric spark which burn a small hole in a piece of metal through witch it contacts. The spark generated by this process produces heat, which remove metal by erosion and evaporation.

Shape Adaptive Grinding (SAG) is an innovative and low-cost machining method that we recently proposed1). Difficult ceramic materials can be machined by SAG from a very rough condition (above 1 µm Ra) down to a very fine optical surface finish (below 0.5 nm Ra). The basic principle of SAG machining is shown in Fig. 1.
