Method for optimizing process parameters in machining for chip removal to maximize productivity with respect to the maximum permissible wear band for the tool comprising the steps of:

to. Defining the conditions for the contour of the workmanship, said conditions comprising at least the material to be machined and the type of tool used;

b. Define the process parameters to be used for tool wear estimation, said parameters comprising at least: the tool-material contact time (t), the cutting speed (v) and feed (), and define For each of these parameters, a range of variability within which to search for optimal values;

c. Define a plan of experiments in which, for certain values of said parameters, the tool wear is analyzed at discrete time intervals and perform such a plan of experiments

d. Based on the data collected in point c. Estimate a regression equation that estimates the tool wear lip dependence (VB) from said process parameters;

is. Solve an optimization problem in which the values of said process parameters are determined, which minimize production time and minimize the number of tools used

Characterized in that:

In solving this optimization problem referred to in point e. It is imposed as a constraint respect for a maximum wear value (VBLim) of the wear lip (VB)

And from the fact that

For the estimation of wear lip dependence on process parameters, the estimated relationship at point d is used.
