Cut monitoring
Within the framework of the ‘Cut monitoring’ project, the IMI-Arc has developed a method for defining
and controlling the parameters that influence the cut during machining by stock removal. Thanks to
the optimisation of cutting parameters, it is then possible to:
• define the optimum geometry of cutting tools and develop anti-wear coatings for these tools
• identify stable working conditions, to avoid damaging tools, i.e. breakage and chipping
• adapt tool choice to machining conditions
This study required the development of an acquisition and processing software for cutting forces when
turning, drilling and trimming. The acquisition of the data required for monitoring cutting forces is carried
out through dynamometric tables. The method developed compensates the frequencies specific
to these tables, improving measurement precision. Based on the cutting force calculations, one can
characterize the temperatures inside the extruded shape and on the surface of the cutting tool. The
various vision systems developed in this project also allow wear measurement directly on the machine
during the formation of the extruded shape.
