    If you're worried about the drill grabbing, brass the drill. Delrin won't care.

    I would not be adverse to drilling it half and half undersized and hitting it with a boring bar to pretty it up.

    WCS= Work Coordinate System ie the “XY” plane the tool is working on. If you want the tool to come in 90* from the front face there’s a good chance you need a plane that is in the desired orientation.

    I get the same error in gibbscam when trying to subtract bodies occasionally, you just have to work around it.

    You can get similar angle boxes from from chinese sources for $10-20. I definitely would not pay grainger's price. All of them seem to have a hold function.

    Another name for a 2 flute endmill.

    A down cut bit or a sacrificial topper to support the CF are probably the easy solutions but I've had good luck pecking 3mm holes on size with just a regular...

    It’s pretty hard to beat something like a VF/VM3SS considering your budget. Hell you can get into a UMC750 for about $145k with a 12k spindle.

    You can use ether a Tan (opposite and adjacent) trig function


    Tanθ=opposite/adjacent

    I think you’re looking at a PCD insert, on the bright side if you don’t crash it it should last you quite a while.

    Wind it up as fast as she’ll go you’ll probably break a chip too.
