CNC engraving machine CNC system graphics trajectory tracking module, knives, road

CNC engraving machine CNC system of graphic display, knife road using a wrapper class CCutsimulator trajectory tracking module, and real-time display in 0 pengl ways people read buffer of NC program planning by the knife track road. Which has two kinds of 2 d and 3 d graphics display mode, 3 d display is actually machining cutter path information, just using 0 pengl, and define some shortcuts to control the rotation of the view of the different azimuth, which can see dao way of space information. Cutter path trajectory tracking application GE motion controller library function instruction: CT— Get a swollen nt to read all the control shaft in the continuous trajectory planning location value; G1LGetA Ⅱ P0s read the actual location of the specified control shaft. Program to compare the two function value, and real time compensation, achieve the CNC engraving machine tool movement at predetermined planning path.
