Before the g-code can be written, the transition points for the machining tool path needs to be determined. In g-code, the tool path is represented by a series of linear and circular moves. Each transition point, ie where straight line meets a curve or where curves of different radius meets, needs to be specified in terms of its X-axis and Y-axis coordinate.
