and manufacturing industries. 2. History The Department of National Defense in Canada contracted Dr. Sam Visaisouk to determine the feasibility of ice blasting for cleaning in confined spaces such as inside ships. The prospect of a dustless abrasive blasting process was very appealing on environmental and worker safety compliance grounds. This effort led to the first operating commercial ice blast machine in 1992. These ice blast machines had complex operating system controls and required frequent

State of the art on Bio-cutting fluids in Machining Submitted by: Abstract The increasing attention to the environmental and health impacts of industrial activities by governmental regulations and by the growing awareness level in the society is forcing industrialists to reduce the use of mineral oil-based metalworking fluids as cutting fluid. Cutting fluids have been used extensively in metal cutting operations for the last 200 years. In the beginning‚ cutting fluids consisted of simple

formula f = RPM x p / 120 where f is the frequency (Hz)‚ RPM is the rotor speed (revolutions per minute) and p is the number of poles formed by the stator windings. A synchronous generator is essentially the same machine as a synchronous motor. The magnetic field of the rotor is supplied by direct current or permanent

1. Introduction The first lathe machine that was ever developed was the two-person lathe machine which was designed by the Egyptians in about 1300 BC. Primarily‚ there are two things that are achieved in this lathe machine set-up. The first is the turning of the wood working piece manually by a rope and the second is the cutting of shapes in the wood by the use of a sharp tool. As civilizations progressed‚ there have been constant modifications and improvements over the original two-person lathe
