How to Use a Surface Grinder Machine

The type of grinding wheel employed for a particular operation is one of the major considerations in the proper selection of cutting speed. In general practice, the wheel will be selected for the material to be cut. The recommended cutting speed can then be determined by the wheel type, bond, and grade of hardness (Table 5-1 in Appendix A).

Difference Between Roughing and Finishing in Machining

Oct 23, 2018 Conventional machining processes are suitable for high stock removal as well as imparting reasonably good surface quality. However, achieving both in a single pass is not possible. Thus machining is usually carried out in two steps with varying process parameters (cutting velocity, feed rate and depth of cut).

CR was the first digital radiographic technique to be introduced. Systems are based on an imaging plate that is similar to the amplifier screen of a conventional radiography unit. The difference is that this storage phosphor imaging plate retains information from incident photons as a latent image.

Kohlbergs Theory of Moral Development Simply Psychology

Kohlbergs theory proposes that there are three levels of moral development, with each level split into two stages. Kohlberg suggested that people move through these stages in a fixed order, and that moral understanding is linked to cognitive development.The three levels of moral reasoning include preconventional, conventional, and postconventional.
