I'd also be interested in the answer, I may very well need a camshaft or two cut if it does... |

They can also cut hexagons. No idea if Andrews can but this is a machine doing it. |

Well the model certainly can do fancy things like that - there is a special firmware package called 'Traub Polyform' that can be incorporated. I don't yet know if it is in my set up. It's called up by special G & M codes. Reading about it it looks quite possible, as it is used when the main spindle has a 'C' axis - ie can be accurately rotated and stopped round the circle, and mine certainly has that feature. Time will tell . . . . . . |

Just some photos I've sent to Traub to hopefully prompt a response to the tool setting issue: #425 - The parameter page that gives the co-ordinates of the setting 'scope (#15 tlml-) #426 - View through the 'scope on tool #10 #428 - The Tool Table with automatically measured value on the bottom line, and my edited (div by 1000) value actually in the tool #10 position in the table |
