Countersinks. • Thread Pitch is fine. 0000001591 00000 n Follow these columns down matching up with the cutter diameter in the left column. In turning and boring, the surface can be defined on either side of the depth of cut (the starting surface or end surface). NOTE: Where a large amount of stock is to be removed, the cutting edge will generally last longer if shallower cuts are taken at higher feeds - as opposed to deeper cuts at lighter feeds. Then decrease speed by 10%. The material to be machined and cutting tool materials will have a large impact on the calculation of cutting speed. Table 4. Chart 3. Therefore, parts with lots of holes requiring pierces will cut much slower than simpler shapes. NOTE: This article covers speeds and feed rates for milling tools, as opposed to turning tools.Before using a cutting tool, it is necessary to understand tool cutting speeds and feed rates, more often referred to as “speeds and feeds.” Speeds and feeds are the cutting variables used in every milling operation and vary for each tool based on cutter diameter, operation, material, etc. Feed 3.
