1. G71/G72 and Cycle95 optimization on cutting productivity

  • G71/G72: Different cutting mode can be selected via parameters:
    • _ZSFI[36] = 0 : G71/G72 works with additional contour cut - compatibility
    • _ZSFI[36] = 1 (default): G71/G72 works without additional contour cut
    • _ZSFI[35]= 0 (default) : G71/G72 works as former version, that means roughing and finishing in G41/G42mode.
    • _ZSF[35]= 1 : G71/G72 works with G40 for roughing
  • Cycle95
    The tool radius compensation can be selected (G41/G42) and deselected (G40) via the following USER DATA
    • _ZSD[13]= 0 : cycle95 works as former version, that means rouging and finishing in G41/G42 mode
    • _ZSD[13]= 1 (default) : cycle95 works with G40 for roughing and G41/G42 for finishing

2. G64 can active in G92 ISO-Mod

No more G60 internal in G92. G64 can be used before G92, and can work.
