DEVELOPMENT OF MINI CNC MILLING 4 AXIS DEVELOPMENT OF MINI CNC MILLING 4 AXIS

Abstract

          The objectives of this study were : 1) design and build  screw feeding support, 2) to study the efficiency of  screw feeding support. The scope of screw feeding support was study of screw working diameter limit 65 mm and  suitable for BRIDGEPORT GX 1600 vertical milling machine.

          The samples for evaluating and testing  screw feeding support  were chosen by 3 experts. The research tool was an evaluation form of efficiency. Data were statistically analyzed by mean

          Research findings were as follows: 1) The moving discrepancy in X Z and A axis are very good, Y axis is good. 2) The machining discrepancy in X and XY axis is good, Y axis is medium, it operation effective.
