请问下MASTERCAM五轴后处理C轴怎么控制在360度之类

应该是c超过360°行程了，所以有抬刀。下面我用debug反推的，不一定对

p_nobrk_emul    #'nobrk' emulation option
      if abs(zinc)<brk_tol | not(abs(xinc)>brk_tol | abs(yinc)>brk_tol)
        | not(mtype = zero | mtype = three),
        [
        if cuttype = zero, ppos_cax_lin #Toolplane rotary positioning
        #prapidout         ---------我是把这里注释掉了，不过下刀高度也没了
        ]
      else,
        [
        nobrk_xa = vequ(xabs)
        nobrk_xi = vequ(xinc)
        nobrk_pa = vequ(p_abs)
        nobrk_pi = vequ(p_inc)
        #Z up, move Z, XY, PRI, SEC
