<p>The device has a computer programmed for effecting acquisition of a geometry of a machine tool (10), and measures of forces (Fn, Ft) with respect to time. The forces are provided by a dynamometric table in a reference mark centered on the machine and their resultant is calculated. The resultant is converted into another resultant in a mark centered on the tool for calculating frictional and shearing forces endured by the tool. Fn is exerted normal to a cut plane defined by a machined surface of a part and is directed downwards. Ft is the frictional force exerted in the plane and directed along the direction of displacement of a cutting edge of the tool with respect to the part.</p> |
