    grab yourself a copy of the machinery handbook. pricey but really handy for this.


    you can buy / use some really nice cutters but it all comes down to how rigid/powerful the machine you are using is.

    dont buy 60 dollar endmills for practice

    there is no standard. All material require a different feed and speed rate.
    don't get the two confused.
    Cutting speed is how fast the tool is turning in relation to the work on a mill or how fast the work is turning in relation to the tool on a lathe
    Feed rate is how far you move the tool per revolution in thousandths of an inch.
    aluminum is 200 Surface feet per minute
    Steel = 90 SFPM
    Tool Steel i.e. 4130/4140 a2, d2, stainless steel = 50 SFPM

    basically you need to remember a 1" end mill in a mill or a 1" bar in a lathe spinning at 360 rpm is equal to 90 surface feet per minute give or take a bit for rounding off the math.
    Cut the speed in half if you run 2" or double the speed if you run 1/2"

    feed rate is something all together different but basically no more then .005" per rev on a lathe and .030" depth for the inexperienced
    or 6 inches per minute feed at .030" depth on a mill.
    Find a machinist and ask questions.
    Machine tools are very dangerous and I've seen parts thrown across the shop or 2" bar bent 90 degrees in the lathe
    BE CAREFUL!!!!

    Someone mentioned the machinery handbook, It's good but also near $75 for a new copy. A better book that I had when I was in my Tech school was the Machinist's ready reference about $20 and has 90% of what a machinist needs to know one a daily basis. Feeds, speed, chip load, tap chart, trig tables, Like I said 90% of the day to day stuff is in there. But when I could finally afford a copy of the machinery hand book i got one. It's an indispensable book.
