In the gear lifetime experiment, the rotational speed of the test gear was set between 750 min- 1 and 1250 min- 1. Table 1 : V ≈ 100 ft/min . If you enter any two of these variables as inputs, the calculator will determine the third variable. Cutting speed. However, there are some circular saws which are not direct drive and operate at different speeds. What is the cutting time required for finishing 100mm width and 300mm length surface of a cast iron (JIS FC200) block when the cutter diameter is ø200mm, the number of inserts is 16, the cutting speed is 125m/min, and feed per tooth is 0.25mm. But a peripheral speed for 1.8*rated speed could be limited to 90 m/sec [300 ft/sec] in order to limit the centrifugal yield and reduce the mechanical stress to an easier solution. Peripheral speed of 12.0 m s-1 yielded the highest threshing efficiency recorded of 97.48 % with the 400 mm diameter threshing drum. The torque M increases with the number of blades.
