The working motion of the machine tool are defined numerically by their velocity. The velocity of primary cutting motion or drive motion is known as cutting speed. Cutting speed is denoted by v and measured in units m / min. Feed motion is measured in following units: 1. Mm / rev in machine tools with rotary primary cutting motion, e.g. Lathe, boring machine etc.
Field Metallography By: Dr. E. Mogire
Principles used in standard metallographic preparation are applicable. This involves rough grinding using coarse grit papers and progressively using finer grit paper before polishing stages as shown in Table 1. Application of inter-stage etching during final polishing is critical especially for creep damage assessment of components. Etching
