Development of a method to compute wear indicators of the prefabricated carbide cutters

The paper proposes a method for computing wear indicators, indicators of wear on the flank surface and the cutting period (durability) of the prefabricated carbide cutters, including replaceable multifaceted inserts with the wear-resistant coating. To approximate the coating hardness as a function of temperature, the paper uses linear, polynomial equations and splines. Calculated dependences of wear on the tool flank surface on the machining time for a workpiece made of corrosion-resistant steel were obtained. The influence of coating thickness, cutting speed and working tool feed on the cutting force and the machined surface roughness was studied. Computed dependences of the tool life on the cutting speed were used to select the machining parameters.
Keywords: method, computation, parameters, wear, durability, wear-resistant coating, polynomial equation, spline
