MODELLING METHOD AND SYSTEM FOR DRILLING PROCESSES

摘要

The invention relates to a method for modelling drilling processes performed by a CNC machine controlled using a control means, in which the CNC machine and the control means are connected by a connection means having a maximum delay of L max . The method comprises the following steps: in order to model a drilling process of a CNC machine, with a first drill and a first material, selection of an equation in the domain of the Laplace transform of type (I); and identification of the values of the parameters in the above equation (p 1 , p 2 , p 3 ,..., p n ), L max and K. According to the invention, in order to model a new process in the CNC machine, with a new drill and/or a new material, the values of the parameters (p 1 , p 2 , p 3 ,..., p n ) and L max are kept constant and it is only necessary to identify a new value for K'.
