Calculator Description
Friction Coefficient Calculator v1
The friction coefficient calculator can be used to determine the sliding resistance between any two material surfaces under load and includes a calculation facility to dimension equivalent Morse Tapers for any material combination

Friction Coefficient
incl. Morse tapers

Subject

Friction is the resistance between two bodies to move relative to each other due to surface roughness. Resistance due to chemical and magnetic attraction is not friction. Any different combination of materials and surface conditions will result in a different friction coefficient; i.e. the proportion of the contacting force required to move one surface relative to the other.

Whilst this phenomenon generates heat and causes wear in machines, it can also be a benefit e.g. in friction clutches and self-holding tapers.

Calculator

Friction includes two calculation options; Frictional Slide and Morse Taper.

Frictional Slide; is used to determine the friction and stiction coefficients for any two surfaces under load and calculates the speed and acceleration of a block sliding down a slope at an angle greater than its angle of repose

Morse Taper; allows you to calculate the dimensions of an equivalent Morse Taper (0 to 7) for any material combination (i.e. any friction coefficient). That is, you can design self-holding tapers made from wood or plastic or a combination of the two with the same capacity of a given Morse number.

First you determine the friction coefficient of your two chosen materials (and surface conditions) using the Frictional Slide calculation option and then design your self-holding taper using that friction coefficient.

The friction calculator technical help menu provides a list of generally accepted friction coefficients for numerous material combinations.

For help using this calculator see Technical Help
