                                                        ABSTRACT

                              Accurate prediction of cutting forces is very essential due to their significant impacts
                          on product quality. During the past two decades, high pressure cooling (HPC) technique
                          is starting to be established as a  method for substantial increase of productivity in the
                          metal cutting industry. This technique has proven to be very effective in machining of
                          hard-to-machine  materials  such  as  the  nickel-based  alloy  Inconel  718,  which  is
                          characterized  by  low  efficiency  of  machining  process.  However,  modeling  of  cutting
                          forces under HPC conditions is very difficult task due to complex relations between large
                          numbers  of  process  parameters  such  are  pressure  of  the  jet,  diameter  of  the  nozzle,
                          cutting  speed, feed, etc. One of the  ways  to overcome such difficulty is to implement
                          models  based  on  the  artificial  intelligence  tools  like  artificial  neural  network  (ANN),
                          genetic  algorithm  (GA),  particle  swarm  optimization  (PSO),  fuzzy  logic,  etc.  as  an
                          alternative  to  conventional  approaches.  Regarding  the  feedforward  ANN  training,  the
