SpecificationsPublicationAdvantagesPurposeExampleCostWe would prefer if all plate and sheet were flat. Unfortunately, the reality is quite different and the standard commercial specifications to which these products are produced recognize this reality. The requirements on the flatness of the plate and sheet products sold by Rolled Alloys vary considerably by the type of product, by alloy, by thickness and by the size of the piece. AMS and ASTM standards exist which cover the flatness requirements for most plate and sheet items as produced by the mill.

Slaying Stainless Steel Machining Guide - In The Loupe

Material PropertiesTool SelectionRunning Parametersin ConclusionStainless steels are high-alloy steels with superior corrosion resistance to carbon and low-alloy steels. This is largely due to their high chromium content, with most grades of stainless steel alloys containing at least 10% of the element. Stainless steel can be broken out into one of five categories Austenitic, Ferritic, Martensitic, Precipitation Hardened (PH), and Duplex. In each category, there is one basic, general purpose alloy. From there, small changes in composition are made to the base in order to create specifiSee more on harveyperformanceA Machinists Guide to Trochoidal and Peel Milling Make Flatness issues milling 304 stainless Practical MachinistPeel Milling Principles. The basic idea here is to use a small stepover, usually around 10% of the tools diameter, but max out the Z depth. Of course, when using this method in the real world, youre best off consulting the cutting tool manufacturer for recommended cutting parameters, but these numbers are usually pretty realistic.Speeds and Feeds 101 - In The LoupeOct 02, 2017Many tooling manufacturers provide useful speeds and feeds charts calculated specifically for their products.
