PLASMA ARC MACHINING.
Abstract
The concept of metal removal by Plasma-Arc machining utilizing DC transferred and non-transferred arc techniques was explored. Tests on various metal alloys at a power level of 50KW show that optimum torch-to-work geometry, feed and surface speed provide high removal rates. Surface finishes of 30 microinch (RMS) were obtained and metallurgical changes were generally of a surface nature. A variety of workpieces including low and medium carbon, low alloy and high nickel steels and titanium were used in the tests. (Author)
