Chapter One Programming Fundamental 1.6 Programming Coordinate Programming coordinate is for workpiece coordinate system. GSK928TEa programming uses absolute coordinates (X, Z) ， incremental (relative) coordinates(U, W) or compound coordinates(X/W, U/Z) . 1.6.1 Absolute Coordinate Values The absolute coordinate value is the distance to the coordinate origin, i.e. the coordinate position of the tool traversing to the end point as Fig.
