WebGeneral principles of machining stainless steels Introduction. The most common and hence most frequently machined stainless steels are the austenitic types, such as grades 304 (1.4301) and 316 (1.4401). These are characterised by their high work hardening rates and poor chip breaking properties during machining. Web60. Speeds and Feeds Formulas. Speeds - Inch. SFM = surface feet per minute. RPM = SFM X 3.82 / Tool Diameter. Speeds - Metric. SMM = surface meters per minute. RPM = SMM X 318.06 / Tool Diameter. Radial Depth of Cut in Percentage of Diameter.

WebApr 15, 1998 · Generally speaking, if chip color is off, check cutting speed. Example: if your steel chips are not deep blue, but brownish, increase machine speed. If the color is silver, it means the chips may be getting too hot. Decrease speed. In stainless steel, aim for wheat-colored chips and in cast iron for grayish-red.
