Apr 05, 2007 · Ed has got it. 572 has a tensile strength of about 10-15% higher than a36. This will allow better cuts, nice curled chips. Run more feed and less speed in gummy materials. But this 1045 steel will probably machine the best of the three. john A572 Structural, Carbon & HSLA Steel Plate - Chapel SteelA572 is a high strength low alloy steel plate used in a variety of structural applications. The most common grade Chapel Steel stocks is Grade 50.

DRILL FEEDS and SPEEDS "Different drilling conditions make it impossible to develop any rigid rules for feeds and speeds." The following tables contain guidelines which can be utilized when drilling standard materials. Also, the following rules of thumb can be used to determine proper feeds and speeds for drilling ferrous materials. (NOTE:varying conditions can easily require adjustments ).

Therefore, it only covers 2 variables. They use multiple charts, add columns and rules of thumb to cover a few more variablesmaybe 4 to 6. Sophisticated feeds and speeds software lets you master a lot more variables than you could manage by hand.

High Efficiency Milling can be a very effective machining technique in stainless steels if the correct tools are selected. Chipbreaker roughers would make an excellent choice, in either 5 or 7 flute styles, while standard 5-7 flute, variable pitch end mills can also perform well in HEM toolpaths.. HEV-5. Helical Solutions offers the HEV-5 end mill, which is an Speeds And Feeds For Milling With End MillsMilling Speeds and Feeds Charts The most important aspect of milling with carbide end mills is to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
