Bluefin -

I agree completely, but somehow I manage to live in safety with the cheap .125 and smaller endmills (probably because I still feed them way too slowly), but managed to chip all 8 teeth of my 1.5" cobalt shell mill (and I'm not sure exactly when, either) by feeding too deep (at least that must be what did it). It's not unusable, but annoying that it was almost new and now I have to make another pass to clean up the little ripples.

Also, I "touched off" two corners of a .375" carbide 4-flute last week using the safer (I thought) method of raising Z until a .125 drill would just roll underneath. I'm designing my electronic touch probe now.

I'd love to get a few of those super aluminum mills, but I don't think I have passed the semester exam on feeds and speeds yet in order to get any advantage from one.

I should probably just give myself a $100 a month "tuition" allowance for a few months to stay in school at Enco and MSC. I might get that one past the boss if I present it that way. As long as she doesn't "pack my lunch" for school, I'll be OK!

Just think how much the tuition would be if we didn't have the internet to share lessons with each other...

It must be that or something like it. I think I looked up G40 the other night, but haven't had the courage to try another "wizard" since then. Whatever it is, I'll post it here on the net and then make a habit of typing it any time I cancel a program, wizard-created or not.

I don't hear others complaining too much about it, so it must just be me and the way I stop and reset programs while I'm setting up for a hot pass.
