CNC machining Milling arcs I and J usage
IJK is actually used to represent XYZ, in the processing of the whole round when used,
Generally only I and J, because we often processing the circle are in the XY plane,
For example, the center coordinates are (0,0) The arc starting point is (10,0) then I equals 10J equals 0
It can also be used to subtract the coordinates of the circle from the coordinates of the arc starting point
