Finish on soft plastics

[A_Camera]

More parts per sheet, some small parts are made from that same sheet, less tools to stock, less tool changers.

But I could get away with a 3mm cutter on that part without an extra tool change, I've done a finish pass on some 10mm acrylic with the same 2mm cutter to give a clean cut in the past.

Yes, more parts but also greater risk for tool deflection if you are using 2mm cutters.

Only really any good doing full clean up passes on new cutters or soft material other wise you still get cut lines.

But we are discussing soft material here... aren't we?

Also, the full pass cleaning I normally make is just shaving off about 0.1mm. That gives very good results, even if the cutter is not brand new.
