For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower. Torque, on the other hand, is the expression of a rotational or twisting force. In vehicles, the engines rotate around an axis, thus creating torque. Torque can be viewed as the "strength" of a vehicle.

Horsepower may also be expressed as 1 hp = 33,000 foot-pounds/ minute or 1 hp = 550 foot-pounds/second. $ Refer to the example of one person exerting 40 pounds of force to pull an object 2 feet in 2 minutes. The amount of horsepower produced is: 40 pounds x 2 feet 2 minutes x 33,000 = 80 foot-pounds 66,000 = .001 horsepower.

When the required machining power value is about the same as the milling machine's rated power, milling productivity approaches its maximum. Torque (T s ) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t ) and can be calculated by the formula:

Translate that to a 20 HP milling machine and it's 20 cu in/min The tool used wether HSS or Carbide does not really mater much, Carbide just runs faster and the metal removal rate is higher. RPM depends on tool diameter and material being cut and feedrate depends on the strength of the tool. Get out your Machinerys Handbook...

Milling cutters can consume significant amounts of horsepower. Very often it is the lack of horsepower that is the limiting factor when deciding on a particular operation.On applications where large diameter cutters or heavy stock removal is necessary, it's advantageous to first calculate the necessary horsepower requirements.

The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm 'a' λ =0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure.

Cutting speed, also known as surface speed, refers to the speed at the outside edge of the tool as it is cutting. It is measured in surface feet per minute (SFM). Cutting speed is mainly depending on the type of materials and cutting tools, related to their hardness. The harder the material, the slower the cutting speed should be.
