Questions on using a moving gantry style mini-mill...

I thought you meant for the Z axis tool length probing. For that, you need to use the tool, and use an isolated plate.

Yeah I got that working perfectly, very slick ;)

It was the edge wizards I was interested in now.

[Ger21]

Then you need to use a real probe.

[Davek0974]

ok, thanks, will do some searching.

[Ger21]

If your probing to an edge, you can use an isolated plate along the edge and specify the plate thickness. Then just use a precision dowel to probe with.

Interesting idea, thanks.

Back to my OP, still working out the niggles...

Where i am roughing with the 5mm tool, i have 2.5mm rads in all the internal corners, the finish tool of 2mm will plough into these at full speed - recipe for breakage here ??

Where we sorted the three slots out on the left with the roughing passes on the small tool, would it be better to pre-finish pass the whole part with the 2mm tool to bring the corners down to 1mm rads+finish allowance and then run once round with the finish pass at full depth??

This would mean i get rid of the fiddly pre-finish op on the three slots as they will come under the new full pre-finish runs. These runs would be contouring at 0.6mm DOC per pass.

I recall JAZZ mentioning it should be ok on page 1 but having seen a 2mm tool now, it seems a heavy cut on the full height of the tool??


The green section plus the portion from the base of the 5mm circle etc. plus an extra 0.1mm finish allowance (not shown)
