What is the cutting power required for milling tool steel at a cutting speed of 80m/min. With depth of cut 2mm, cutting width 80mm, and table feed 280mm/min by Φ250 cutter with 12 inserts. Machine coefficient 80%. （Answer） First, calculate the spindle speed in order to obtain feed per tooth. n=1000vc÷πDC=(1000×80)÷(3.14×250)=101.91min-1

Mar 21, 2011 · MRR = .200 x 1.64 x 19.5 = 6.4 in3/min. For horsepower at the motor (HPm), use formula: HPm = HPC/E. In determining horsepower consumption, “K” factors must be used. The “K” factor is a power constant that represents the number of cubic inches of metal per minute that can be removed by one horsepower

Unit power (hp/in³/min) = Spindle horsepower (hp) Spindle horsepower (hp) ÷ Machine efficiency (%) / 100 / 100 = Motor horsepower (hp) Spindle horsepower (hp) × 63,030 × 63,030 ÷ Spindle speed (RPM) = Spindle torque (in∙lb)
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

Johnson and Bahamonde (1996) also developed a formula for the calculation of peak and average power from the vertical jump test, using the countermovement jump. These equation use the additional factor of body height. Power-peak (W) = 78.6 · VJ (cm) + 60.3 · mass (kg) - 15.3 · height (cm) - 1,308
It was concluded that vertical roller mill circuit has an advantage over conventional ball milling circuit in terms of energy consumption. ... Spec. motor power ... and calculating the rates of
The formula for the electric power is P = π/2 * r² * v³ * ρ * η, one watt is calculated as 1 W = 1 kg * m² / s³. Example: an offshore wind turbine with a radius of 80 meters at a wind speed of 15 meters per second has a power of 16.3 megawatts, if air density and efficiency factor have the given values
A small, vertical-axis wind turbine has been mechanically coupled to a positive displacement pump for pumping from shallow wells or lakes. The 4-kW turbine is 5.5 m high and has an equatorial radius of 4.5 m. Power is transferred through an electric clutch, which allows the turbine to be started in a no-load condition (Fig. 8). The rotor operates between 160 and 250 rpm, with corresponding flows of 10 to 15 …
