    What insert to turn internal cone with radius?

    What boring bar/inset would you guys use to cut this internal profile? I ground a HSS bit to make a couple of these, but now need to make more and using HSS in 4140 prehard isn't very appealing. Dimensions in inches if it isn't obvious.

    Setting Renishaw probe diameter

    Dumb question- anyone know how to set the probe tip diameter on a Brother C-00 control? It's got to be buried in a macro variable somewhere, but not sure where exactly. I'd ask Yamazen directly, but I bought this machine used; the one bought new doesn't have a probe, and I've already bugged...

    Speedio speeds/feeds in steel and stainless

    There's a bunch of threads and info on using 30 tapers on aluminum, less so about cutting stainless and mild steel. What are your go-to tools and parameters, for starters, on 304, 17-4, 1018, and 4140?

    Changing Local Variable to shift tool setter

    I need to move the tool setter on a S500X1, pushing it about three inches in Y+ to the edge of the table. From looking through the tool setting program it appears that #25 sets the Y offset; I went through the data bank and found the local variables table, but they are all blank. Is there...

    4th axis work flow

    I'm new to 4th axis programming, and not sure about workflow. I have a two sided trunnion with Orange Delta IV vises on each side. How are you modeling fixturing, to get the offsets right? Bringing in a body of the trunnion into each part file and placing the stock in the jaws to get an accurate...
