G73U (△ J) W (△ K)R(d)P(ns)Q(nf)X (△ U)Z (△ W) place of 1-37 seeing a picture is shown, this function is when cutting workpiece, cutting tool contrail is close loop, cutting tool chases advance gradually to give, make close cutting loop is stood by to a zero final figure gradually, final cutting treatment is finished. Its motion contrail is: A1 of → of A → A1 ' A2 of → of A2 of → B1 → ' A of → of A of → of · of · of · of · of · of · of → B2 → ' A of → B → . Among them △ 1, those who be the rough machining on X axis is total the quantity that retreat a knife, its are worth △ for radius 2, those who be the rough machining on Z axis is total D of the quantity that retreat a knife, repeat a time for rough machining: The Ns, ordinal date of the first block that is finish machining course (namely A → A ' the ordinal date of block) the ordinal date of the Nf, the last block that is finish machining course (namely B → B ' the order of block; And instruction of the F that adds a statement when essence of life, S, T is invalid, ns dictates to the F in Nf block, S, T effective. %1038 (1-38 seeing a picture) N1 G92 X52 Z190 N2 G90 G00 X44 Z130N3 G73 U3 W1. 5R3 P10 Q15 X0.
