Lifter profiles play a key role in the performance of tumbling mills since they influence the motion of mill charge.Since lifters change profiles during their useful life due to wear, the performance of tumbling mills will correspondingly vary as a function of time.There is therefore a need to predict forces.

Strong milling forces come into play during roughing power milling.Depending on the tool spindle speed, the resonances in the machine tool and the chip volume cutting power during milling, the tool can sometimes begin to chatter.Because chattering places an extreme load on both the tool and the machine, it is considered.

Calculate an approximate average impact force and peak impact force from a collision of a moving body with output in Newtons N, kN, MN, GN and pound-force lbf. The impact force calculator is versatile and can also be used to calculate the mass, velocity and either collision distance or duration. Works as a car crash force calculator, falling object impact calculator, etc.

The formula for impact force expressed in terms of the bodys velocity speed on impact v, its mass m, and the collision distance d is the first formula below.

The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash. The formula can easily be extended to calculate the approximate maximum impact force a.k.a. peak impact force by multiplying the resulting average impact force by two.

Example 1 Car crash force. A car weighs 2400kg 2.4 tonnes and is moving with a constant speed of 27 kmh when it hits a light pole head on. The deformation distance is measured at 75cm. What is the impact force of the car.

Example 3 Calculating the impact force of a falling object, without taking into account air friction. Lets say there is a 250 kg piano hanging 5 stories high or about 15.5 meters and we drop it on hard concrete. What is the impact force, if we measure that the collision pulse is about 0.2 seconds.

During face milling operations, the workpiece should be fed against the milling cutter so that the pressure of the cut is downward, thereby holding the piece against the table. Whenever possible, the edge of the workpiece should be in line with the center of the cutter.

Ball-end milling is a very common machining process in modern manufacturing processes. The cutting forces play the important role for the selection of the optimal cutting parameters in ball-end milling. In many cases the cutting forces in ball-end milling are calculated by equation from the analytical cutting force.

If you have watched MythBusters, you are aware that they often crash things into each other. In the latest episode, the MythBusters dropped a piano onto the roof of a house. Before the drop, they stated that the piano weighed 700 pounds and would be dropped 50 feet above the roof. Right before impact, the piano would be traveling at 38 mph and have an impact force of 12,000 pounds.

The specific surface area of particles is increased while performing particle refinement to a defined size. This increase is normally accompanied with increasing number of surface defects, which are centers for reactivity. Thus, comminution of particles results in a chemical activation of solids which can cause reactions between solids. This is called reactive milling.
