It is not necessary to command point A by G72 in the block next to N732
nor point B by G72 in the block next to N735.
WARNING
1 Since radius, straight line length in G68 and G69 are not
modal data, they must be commanded correctly in every
block.
2 It is possible in certain machines that nibbling is not
performed by G68 or G69 command, but one-cycle
punching is executed at respective positioning points.
