Hi people,

In the Profile Operation/Finish window of Solidcam I don't understand the function of
the Extension/Overlap field and can't seem to enter values that make it alter the path.
I thought it might do a finishing pass over the roughing wall offset which would be handy.
Any clues please.

Cheers,

Brian Harris

Lets say your are machining a closed profile. You start and end at exactly the same location. Sometimes your tool might flex at that point and it leaves what some in America call a witness mark. The extension/overlap value makes it go all the way around one time and keeps going past the starting point by that value.

Thanks for the explanation, Adam.

Brian, this is a great tool, and I find myself using it as often as possible.

On one job you could see the witness left by a chamfer tool. I adjusted the lead in and out rads until it was as good as gone, but then overlapped the tool path just 1mm and it was gone completely.

I'm loving Solidcam!

Thanks mattpatt, and yes, Solidcam's great.
