WORKPIECE MATERIAL CUTTING SPEED (SFM) TIALN EXAMPLES This chart provides starting parameters for calculating speeds and feeds. >> Cutting speed is mainly depending on the type of materials and cutting tools, related to their hardness. The most essential consideration in selecting feed and rate is the kind of material that is to be cut. The RPM calculated in the Turning(Lathe) Speed and Feed Calculator refers to the spindle speed in turning process, and the IPM refers to feed rate. In the case of lathe machine cutting speed is the peripheral speed of the work past the cutting … endobj CUTTING SPEEDS AND CUTTING FEEDS Cutting Speed is defined as the rate at which a point of the work circumference travels past the cutting tool. For convenience, Knurling is often performed at the same speeds used for turning operations when using high speed steel tool bits. The exact RPM is not always needed, the following calculator (formula) may be used to estimate the value closely. << Turning operations remove material from a rotating workpiece by feeding a single-point cutting tool axially, along the side of the workpiece. /CS/DeviceRGB << /Parent 50 0 R /Width 531 Counterboring Speeds and Feeds. >> /ModDate (D:201801111649Z) << Turning Problems.
