Cutting force can be measured by using force transducers, as well as tool dynameters which are mounted on the tool holder or the work holding device on the machine tool. Forces can also be calculated from the amount of power consumption during cutting, often measured by a power monitor, provided the mechanical efficiency of the machine tool can be determined.

A mechanical tool dynamometer which is shown in the figure measures deflection on the tool holder by the use of sensitive dial gauge and a lever, the end of which is connected with the tool using a roller and a screw.

The important reasons for measuring the force are:

1) To estimate the various power required in a machine tool.

2) To estimate the forces acting on the tool, that must be resisted by the machine tool components, bearings etc..

3) To survey the characteristics of new work and tool material
