Abstract

As the only cold high-energy beam machining technology, abrasive water-jet (AWJ) is one of the most rapidly developed techniques in material manufacturing industry. However, the application of AWJ is limited by the cutting accuracy it can achieve. Kerf profile generated by AWJ is different as the cutting parameters change. As a result, it has become a major factor which affects the cutting accuracy when AWJ is used as a machining tool. Researchers used taper error to characterize kerf profile error generated by AWJ in the past years. And many efforts have been put on how to eliminate taper error by using a tilting cutting head of a 5-axis AWJ machine. However, using taper error to characterize the kerf profile error generated by AWJ is not accurate since kerf profile error might appear in different styles. And using a 5-axis AWJ machine to eliminate taper error is only effective in some special cases. To effectively eliminate taper error, the first thing needs to do is to find out whether the kerf profile error can be compensated or not. Based on research, a key parameter, named kerf profile coefficient O, which can be used to characterize kerf profile error and further to guide people to use different ways to compensate kerf profile error, has been defined in this paper. To further illustrate the efficiency of this coefficient, a series of cutting experiments have been carried out and the experimental results have been discussed.
