XnZnCn: |
Chamfer Dimension |

XnZnRn: | Radius Dimension |

It is possible to automatically generate a chamfer or radius between two connecting linear moves.

Just program X and Z to the theoretical intersection point of the two moves, and put a C or R with the absolute amount of the radius or chamfer needed.

XnZn: | The linear move leading to the intersection point of two features |
---|---|

Rn: | The n is the absolute value of the radius used to blend the two features |

Cn: | The n is the absolute value of the chamfer used to blend the two features |

The C or R command will not work with blending arcs or arcs and lines. If you want to blend these use G02 and G03.

- The moves do not have to be at right angles.
- The chamfer created is set back equally from the intersection point of the two features.
- The radius created is made tangential to the two intersecting features. The direction (CW or CCW) of the radius is determined automatically by the OmniTurn. It looks ahead to the next move.

Here's a simple example part:

The program would be:

g90g72g94f300 | (header) |

t1 | (lh turning tool) |

x0z.1 | (starting point) |

m03s2000 | (set spindle on, 2000rpm) |

g95f.003 | (feed 0.003 ipr) |

z0 | (move to z0) |

x.375c.063 | (move toward x0.375, to chamfer) |

z-.375r.063 | (move toward z-.0375, to fillet) |

x.75 | (finish fillet, move to x0.75) |

x1z-.5r.063 | (move at 45° toward z-.5, to fillet) |

z-.75 | (move to z-.75) |

x1.01 | (clear part) |

g00z.1v | (rapid to start point) |

m30 | (end program) |
