The new system for the control of air toxics being developed by the United States Environmental Protection Agency called the "Maximum Achievable Control Technology" requires the development of technology based standards for Hazardous Air Pollutants within a specific industrial or commercial source category. This paper attempts to provide a comprehensive understanding of the rule and its applicability to shipbuilding and ship repair industry. The reasons for selecting California regulations as the shipyard maximum available control technology, the compliance procedures, the control technologies for paints as-supplied and paints as-applied and other general requirements under the MACT rule are discussed in detail in this paper.

Theory And Experiment

The cutting vibration is one of the main factors to affect precision machining. In this paper, the influence of tool rake angle on cutting vibration is studied at different cutting speed in turning operation, and corresponding theoretical analysis is made. The experiment results show that: the amplitude of machining vibration gradually decreases with tool rake angle increasing; while rake angle o g <0°, the biggest amplitude occurs at V=50~70m/min; While o g ≥0°, it is at V=160~180m/min. Moreover, theory and experiment foundation is presented on avoiding the biggest amplitude range so as to guarantee quality of precision machining at high speed.
