| Abstract | Abrasive waterjet machining (A WJ) is a nontraditional machining process where its main activity is in cutting process for a wide range of materials. A WJ delivers a good quality cut with low heat affected zone; therefore, it is suitable for applications that are sensitive to thermal deformation. However, AWJ machine, similar to other CNC machines, is not flexible and not user friendly. Many lines of G-code commands are required for generating tool path to perform any contour cut. The more complex the contour is, the longer and more complicated the tool path program will be. Consequently, working on a new contour, unavoidably, consumes time, is prone to error, and requires experience. In order to effectively utilize the capability of A WJ, this research focuses on improving man-machine interface that allows inexperience users to complete cutting any complicated contours in very short period of time without writing a single G-code. A two-axis servo table with a user-friendly LabVIEW-based program has been developed and tested. This developed system allows a user to input commands by dragging a mouse to draw a desired shape. The table, then, controls the movement of a workpiece relative to a fixed waterjet nozzle immediately after the drawing is finished. The system performance has been tested by cutting ceramic tiles. Its cut results have been evaluated and compared with similar parts cut by operating the movement of the nozzle. The cut quality is comparable, but tool path generation is effortless. This research makes it possible to achieve several quality cuts of different contours in minutes rather than in days |
